How Big Is a 100 Ton Boat?

Boating licenses have weight limits, yet boat sellers don't list the weight of their vessels. Knowing the relationship between weight and size is essential.

There is no room to "learn from your mistakes" when you're buying a boat, but there doesn't seem to be enough information to learn from others' mistakes either. If you look up the size of a 100-ton boat, every resource seems to say that "it depends." And you cannot afford to buy a boat that is outside the license restrictions.

A 100-ton boat is 65 feet long and features an average of 2 stories. It weighs around 55 spans and has a total length of 165.6 feet. This is more than the length of a football field and weighs as much as 4 Boeing 747 planes!

In this article, you will discover everything you need to know about buying a 100-ton boat, including what factors affect the size and what is the size where the returns start diminishing while liabilities increase. But first, we must address the height and length debate.

The height of the boat is not included in the general 'size' declaration. Your boat's size will almost always describe the length only. The height measurement is usually available as well but is not positioned as the size. This might make you wonder if the vertical size matters less than the length.

Table of contents

‍ is boat length more important than height.

The boat length is more important than height if you would like to arrange large gatherings, while the height matters more if you want to spend more time on the boat with fewer people. Multi-story boats offer enough variety on board to offset the monotony of long-haul cruising.

You should decide between a higher clearance boat and a bigger size (longer) boat early on because a 100-ton boat is going to distribute the weight vertically or horizontally. If you want a boat that is longer than 65 feet, you might have to sacrifice the third level on your boat. If you want it to be double the length, you might barely fit a single cabin on deck. Knowing what you want to use the boat for is going to inform what you get out of the boat.

If you want to hold parties where groups of four or five break off and hang out, then a multi-story boat is much better. But if you want to host large gatherings that stick together, then you need a long enough size to fit everyone in the same space.

According to the Fox Island Bridge Marine Survey, a 35-feet clearance is preferred by most participating boat owners, based on the maximum aircraft of their tallest boats. If the maximum height of a boat is under 35-feet, you might be able to halve the length of a 100-ton boat by simply increasing its vertical length. Whether that is prudent or not is up to the buyer to decide.

Buying a 100-Ton Boat: How to Judge by Size?

Very often, the weight isn't even listed by sellers, and it can be a waste of time to call for price and then inquire about the weight when you're not even allowed to captain a vessel over 100 tons. It is best to stay within 65 feet to 79 feet range when looking for boats just to make sure you're getting the right-sized boat.

1982 Alalunga 72 is a classic yacht with a 76ft length. It is very likely to weigh 100 tons, even though its weight is not expressly mentioned in its specs. The weight of this vessel is estimated from the loss of vertical height (it doesn't have two covered levels/floors), which is in proportion to the gain in length. An 11-foot increase in horizontal size requires around the same materials as a 15-foot increase in vertical height. This brings us to the following size probabilities for a 100-ton boat.

• Triple story – 54 feet
• Double story – 65 feet
• Single story – 76 feet

A margin of error of around 2 feet is still required to get a good estimate. Remember, the final weight specification should be declared by the seller, but if a boat's size is not mentioned, you can go by the measurements listed above when creating your shortlist. And if you're looking for a boat for social use with your family and friends, then the 1982 Alalunga 72 might be one option to consider.

This vessel has a history as it was built in 1982 and has survived decades without getting refurbished. In 2016, the boat was structurally and visually improved, refitted with the latest amenities, and essentially built anew. The teak and mahogany aspects remain consistent, though.

It can be used for casual events like small cocktail parties and small-scale gatherings. The balance it strikes between value-for-money and luxury allows it to be used for casual gatherings with middle-class friends and as a background for a networking event with corporate peers. Since the boat is refurbished for comfort, it is best used as a personal abode.

Because a bulk of the boat’s value lies in its history, your acquisition won’t adversely affect its value by a lot. Still, the drawbacks of owning a second-hand vessel apply, and you might not get an immediate buyer willing to purchase the boat at the price you want to sell. Due to the nature of boat sales, there are no public reviews of this or any other boat. So, whenever you purchase a boat, you have to judge it personally.

Best Practices for Buying a 100-Ton Boat

• Confirm the weight – It is crucial that you don’t take the size to weight conversion as universally true and confirm the gross weight of the vessel.
• Get the material specs – Understanding the material used in building a boat will help you understand the value-for-money of the boat and its size economy. A 100-ton boat made from heavy materials has less space.
• Seek warranty if applicable – Finally, get any and every assurance you can get on paper. There has to be a money-back guarantee on the weight claim because you cannot personally weigh a boat, and if the licensing authorities find it otherwise, you don’t want to be stuck with a vessel you cannot captain.

Final Thoughts

Since the captain's license does not cover boats that weigh more than 100 gross tonnes, you should get a 65-feet-long boat after confirming its weight with the seller. On average, you should shortlist boats that are 54 to 76 feet long, then get their weight confirmation.

100 Ton Captain's Licensing

Take the exams with us! These are in-lieu-of-exam courses, which means you take the USCG exams at our school. This provides you the opportunity to relax and test in a familiar environment where you’ve been practicing. Successful completion of our course earns you a certificate that you take to the USCG.

Our Master License courses offer two weeks of classroom instruction by professional, licensed captains. We don’t simply “teach to the test”; our instructors provide the highest quality classroom instruction to give you the skills and knowledge needed to operate a vessel with confidence. Our staff will help guide you through the whole process, including documenting your sea time and assisting you in the application process.

100 Ton Master Inland/Near Coastal: This is the course for you if you're working as a deckhand, looking to make your way into the wheelhouse, or you own your own vessel and are interested in operating private charters. Our 100 Ton License course is 80 hours, runs two weeks (Monday-Friday 8 a.m. to 5 p.m.), and covers:

• Rules of the road
• Navigation and Chart Plotting
• Deck General
• Deck Safety & Environmental Protection
• Navigation General

Operator Uninspected Passenger Vessels (OUPV) Our 100 Ton Captain's course is also approved to meet the requirements for Operator Uninspected Passenger Vessels (OUPV), commonly known as a Six Pack License.

What does this mean to you? A Near Coastal License may be closer than you think. With only 90 days of Near Coastal sea service and at least 360 days total sea service, you should be eligible for an OUPV Near Coastal License. This license allows you to work as an operator of a small charter vessel off the coast. (The vessel must, however, not be inspected, be less than 100 GRT carrying a maximum of 6 passengers, and remain within 100NM of the U.S.)

Special Note: If you have been approved by the USCG for a 100 Ton Master/150 Ton Mate License, you will need to take the 200 Ton Master course to fulfill the exam requirements of the 150 Ton Mate rating.

Why Should I Go Straight for My 25/50/100-Ton Masters?

 Tags: 25/50/100 Ton Master License

If you are on the fence between going for the  OUPV/Six-pack  or the  25/50/100-Ton Master captain's license and you have qualifying boating experience, then we recommend going straight for your Master’s license! The US Coast Guard does  not  require that you get the  OUPV/Six-Pack  before you get your  25/50/100-Ton Master c aptain’s license . This license can allow for more professional opportunities and the ability to make some extra cash.  

First, let's start with what the Master's license is. The USCG Master's license is the highest-level captain’s license. With this license, you can operate INSPECTED vessels (7 passengers or more – like a water taxi or dive boat), as well as uninspected vessels with 6 or less paying passengers, up to 100 GRT. If you qualify for the Near Coastal endorsement, you can go up to 200 miles offshore!  

Inspected vessels will have a COI on board. COI stands for  Certificate of Inspection . Boats with COI's are built for specific purposes, like water taxis and duck boats. Most houseboats are recreational boats and are  not  manufactured with COI's.   

The COI indicates:  

• How many paying passengers aboard  
• Level of  Masters  license that is required  

Now, you may be asking yourself, what does 25/50/100 Ton really mean? Regardless of what Masters you are issued, you will be able to operate uninspected vessels up to 100 GRT. The 25/50/100 Ton indicates the largest inspected vessel you would be able to operate professionally. Based on your boating experience, the Coast Guard will award you the appropriate 25,50, or 100-Ton tonnage endorsement. 

• 25 Ton: up to 50 feet
• 50 Ton: 50-70 feet
• 100 Ton: 65 feet or more (depending)  

Now that we covered what the Master's license is, time to go over its benefits. The Masters is the highest-level license and because of this:  

• Our students report savings of 10-30% on their insurance premium  
• Opens more opportunities since you can operate inspected and uninspected vessels 
• You can take on more paying passengers on inspected vessels to make more money  

The Master's license is internationally recognized, which means  you can use this license when sailing in international waters. However, you must start  AND  end your trip within United States waters with the same paying passengers. This is an extremely important note to remember. You will need to reach out to the other countries you plan to operate in, see if they have additional licenses and/or paperwork that you must have onboard. 

These are a few of the opportunities someone may come across as a licensed captain:   

• Yacht Deliveries  
• Sea Trials  
• Fishing Boat Charter Captain  
• Water Taxi Captain  
• Whale Watch Guide
• Instructor  

Learn more about the opportunities by reading over our  blog .  

There really are no reasons why someone shouldn’t go right for the Master's license. The opportunities are endless, the limitations are minimal, and you get to feel the pride of having the highest-level captain’s license. If you are at least 19 years old and a US citizen, achieve your Masters today. 

Wouldn’t you want the best of the best? So, when you’re ready to get started check out  our courses  here or give us a call at 609-303-0664!

Captain's License USCG - Master or Mate 100 ton Course 101

Course Description

Captains licenses - uscg .

• Course #101 is the Master or Mate of Vessels of up to 100 gross tons.
• Course # 104 is the Operator of Uninspected Passenger Vessel (OUPV – 6 pack) Level.
• MPT’s Captains License classes are USCG Approved, NO TEST AT THE USCG.

This course is available for both levels. The first level is USCG Approved for candidates applying for their Six-Pack - Operator of Uninspected Passenger Vessel (OUPV) License. Also known as the Charterboat Captains License and is 8 days in length for daytime students. This license is for operation of uninspected vessels only.

Any applicant who has successfully completed Master 100 Tons (MARTPT-281) course and who presents Certificate of Training within one year of the completion of training, will satisfy the examination requirements of 46 CFR 11.201(j)(l) for original issuance, 46 CPR 10. 227(e){l)(iii) for renewal, and 46 CFR 10.227(i) for reissuance for any one the following endorsements and may not be used for any application transactions thereafter:

• Master of less than 100 GRT, Near Coastal, or Great Lakes & Inland, or Inland Waters; OR,
• Master of less than 100 GRT, Near Coastal, Raise in Grade from OUPV Near Coastal; OR,
• Operator of Uninspected Passenger Vessels (OUPV) or Mate of less than 100 GRT Upon Near Coastal, or Great Lakes & Inland, or Inland Waters.

U.S. law may allow uninspected charterboats operating in the USVI as defined by the law to carry a safe number of passengers for the vessel up to 12 without requiring inspection provided the vessel meets either the yellow or blue codes for small passenger vessels issued by the UK MCA. This promotes fair competition between the USVI and the BVI for charterboat operators. This allows a Six Pack License to operate these vessels in those specific waters only with up to twelve passengers on uninspected vessels, however a Masters License is still required for any inspected vessels regardless of the number of passengers or area of operation.

The second level affords the student three additional days of classes and is USCG Approved for Master and Mate Licenses or the 3-in-1 for students applying for Master / Mate and Operator. The USCG does not require you to get a Six-Pack License before you get your Masters, so if you qualify, you can take the full 11 days and get your Master or Mates license! Most students do qualify for a Master or Mate license. The Masters level earns you the respect you have earned with years of boating experience as well as giving you the ability to serve on either inspected (like water taxi's or dinner boats, fishing boats with more than 7 passengers, etc) or uninspected vessels as you choose. Another benefit is that with the Master you can go twice as far offshore, with the near coastal route, with 6 pack you can go up to 100 miles offshore and with the Master you can go up to 200 miles offshore!

Gross Tonnage:

The OUPV Six Pack License is valid for uninspected motor and sail vessels up to 100 gross tons and is a national license. There is not an STCW equivalency for this license. The Master and Mate Licenses are valid for inspected motor vessels (aux sail may be added through endorsement, see below) of 25, 50 or 100 tons based on your experience and for uninspected vessels of up to 100 tons automatically. If you are unsure of your vessels gross tonnage our captains license flyer includes a formula or if your vessel is documented this information will be included on the certificate of documentation. Master and Mate licenses can be issued as national credentials or may be issued with an STCW (international) compliant designation when applicable. Additional training and service is required to obtain the STCW designation.

Subjects Include:

Both levels of Captains License classes include training on navigation, tidal calculations, international and inland rules of the road, coastal pilotage, meteorology, anchoring and mooring, marlinespike, docking and undocking, buoyage systems, safety, voyage and passage planning, general ship knowledge regulations, stability and vessel construction, and seamanship.

Written Exams:

This course is USCG Approved. No Tests at the Coast Guard. You will take written final exams administered at MPT at the end of the second week of the course, generally the second Friday for Master/Mate or OUPV. If you are coming in from out of town, we recommend making your travel plans for the following day when possible so you are not rushed during the exam.

The exams include a selection of the topics covered in the course. We work with everyone until they pass! Do not worry. Class participation and study will typically get you through the exams. All exams are administered in accordance with USCG guidelines and students are permitted to retake the exam modules when needed to up to three times and are allowed up to 90 days to study and finish all exams after the course if desired.   Because both the OUPV and Master/Mate students take the exam on the same day, if you qualify for the higher level, you should definitely get it.  Also worth noting, the exams are nearly identical. The only difference is on the deck general portion, the Master has 10 additional questions relating to inspected vessels, etc.

AUXILIARY SAILING ENDORSEMENT: Course #103 Students taking the Master or Mate level and who have obtained sufficient sailing sea time can also take their Auxiliary Sail Endorsement one evening during the course (for an additional fee) and add this endorsement to their license. This is not required for the six pack as the uninspected license does not require an additional endorsement to operate a sailing vessel and therefore the endorsement is applicable only to inspected license candidates.

SEA TIME & APPLICATION PREREQUISITES:

Please see our Captains License brochure and information page on the MPT home page or contact a career counselor for more information. Note that the course certificate must be submitted to the USCG within one year of completion to receive examination credit. 

The application requirements apply only to those individuals wishing to pursue a USCG Merchant Mariners Credential (commonly referred to as a Captains License) after the completion of the course. If you are taking the course for educational purposes only, the application requirements may not apply to you. We recommend that you speak to an MPT career counselor for more information before undertaking the course to be sure it is the right choice for your career and educational goals. Application for USCG MMC/License requirements include (subject to change without notice): • Application for license (with Oath)• Documentation of sea time experience - letters or sea service forms signed by the vessel's owner or captain or sea service forms signed by you for your own boat(s) or DD2-14 and Transcript of Service for your military sea service (if applicable). • Proof of vessel ownership - if you are submitting forms for your own boat(s) • Physical Exam (within 1 year, on USCG Forms) There are certain medical conditions and/or prescription drugs that may disqualify you for a license or require a waiver. Ask for info if applicable. • Drug Screen (within 6 months, on USCG Forms or proof of random program)•Proof of U.S. Citizenship for Master/Mate or Proof of Permanent Residency for six-pack OUPV • T.W.I.C. Card Application; The USCG Conducts a criminal background check and National Driver's Registry Report on all applicants. Certain offenses within recent years can disqualify you for a license. Please ask if you need more information or go to www.TSA.gov • Course Certificate from MPT's or other USCG Approved Course within the last year • First Aid & CPR Certificate from MPT or other USCG Approved course within the last year • MMC/License Processing Fees (evaluation/ issuance paid to USCG through www.pay.gov)

 When you register for a Captain’s License Course we recommend that you also register for the USCG First Aid Course #143 or143S which is required to be taken within 1 year of this course and the FCC Marine Radio Operators (MROP) Permit #130. The First Aid Course can be taken either before or after the Captain's License Course (100Ton); Saturday classes are available (see course #143S) for your convenience. The MROP course #130 is usually offered the second Monday of the 100 Ton course. A program package discount is available for students taking all of the courses together.

This New Superyacht Will Be One of the World’s Fastest

By Katherine McLaughlin

Depending on who you ask, bigger may not always mean better, but in the world of superyacht designs , it does usually mean slower. However, this may soon change with Vanquish’s VQ115 Veloce , which the company has promised will be one of the fastest superyachts in the world more than 30 meters (about 98.5 feet) long.  

The VQ115 is designed for entertaining. 

Commissioned from the Dutch luxury yacht company by a repeat client, the VQ115 reaches an impressive 51 knots, which is a little under 59 miles per hour, and spans 35 meters or 114.8 feet. The 32-seat, three-deck powerboat is set to be delivered to its owner in North America later this year. 

To power the nearly 100-ton boat, Vanquish plans to install three MTU Rolls-Royce 2600s engines that surface drives will back up. When running on the two engines, the vessel will have upwards of a 500-nautical-mile range in addition to an extra fuel tank, which can be used for cruising at 15 knots. 

The yacht has a spacious saloon that leads to an outdoor deck.

A jacuzzi makes it easy to enjoy the water without getting into the ocean. 

The Vanquish team tapped the expertise of Studio Delta, a naval architecture firm, to design the yacht’s hull to minimize drag and increase efficiency when pacing at top speeds. The rest of the exterior, designed by Guido de Groot, is similarly sleek and modern and made from aluminum. 

On board, there will be no shortage of entertainment options. Two smaller Vanquish watercrafts, the VQ16 and VQ11, will respectively be housed on a tender bay and second starboard garage. A live bait tank, bar, saltwater jacuzzi, office space, cinema room, and multiple outdoor lounging and dining area are also part of the design. 

Cabin space was less of a priority as the client wanted more room for socialization. 

Despite its monstrous size, the VQ115 notably lacks cabin space—there are only three sleeping rooms. However, this isn’t an oversight, rather the client’s specific desire for a vessel designed for entertaining and interaction. At its size, the superyacht is sure to deliver on that front in a large way.

Which USCG Captain's License Should You Choose?

OUPV or Master License? Your choice depends on vessel size and passenger count. Learn the requirements and how to upgrade later.

The first step you need to take to get your captain’s license is to decide which type of license you’re going to pursue.

There are two main types of Coast Guard licenses:

License Type #1 - 25 ton, 50 ton, or 100 ton Master License

License Type #2 - Operator of Uninspected Passenger Vessels (OUPV or Six Pack)

The type of license you choose depends on the size and type of vessel and the number of passengers aboard. You can always upgrade your captain’s license and add endorsements along the way.

OUPV/Six-Pack

The OUPV/Six-Pack license is the USCG license that many recreational boaters choose. It’s called the six-pack license because it allows you to take up to six paying passengers and crew members. This allows you to do small fishing trips, sightseeing tours, dive boats, or sail boats.

The OUPV license is also limited to vessels that are 100 gross tons (about 80 feet long).

Many boaters will get their OUPV license even if they have no intention of doing commercial boating. You don’t need to be licensed by the Coast Guard to use your personal boat, unless you’re taking paying customers out on the water.

Getting your license is still valuable because you’ll brush up on your navigation and safety skills. Plus, having your license gives you the option to captain in a commercial setting.

The OUPV qualifies you to captain uninspected vessels. USCG uninspected vessels can carry up to six passengers and aren’t required to be inspected by the Coast Guard. The uninspected vessel must comply with minimal federal standards for safety, navigation, and pollution prevention .

Inland, Great Lakes, and Near Coastal OUPV

There are three types of OUPV licenses that dictate the bodies of water you can operate on commercially.

The Inland OUPV license allows you to captain on U.S. Inland waters . This includes bays, rivers, and lakes (excluding the Great Lakes).

The Near Coastal license allows you to operate on Inland waters and Near Coastal, which is typically up to 100 miles offshore.

The third license type is Near Coastal with Great Lakes. This license allows you to operate on Inland, Near Coastal, and the Great Lakes .

OUPV license requirements

To qualify for your OUPV license, you’ll need to have 360 days of documented sea days. At least 90 of those days must be within the past 3 years. To attain the Great Lakes or Near Coastal license, you’ll need 90+ sea days on the respective waters.

The Small Vessel Sea Service Form CG-719S is used to record your sea days—the number of days that you were on the water (for 4+ hours in a day) in any given month and year.

Once you have the required sea time, you’ll need to:

• Be at least 18 years old
• Get your TWIC card
• Be a U.S. citizen (or show permanent residency)
• Have a valid First Aid/CPR Card
• Pass a basic physical exam
• Pass a drug test
• Complete a USCG-approved course

Read more about How to Get Your OUPV License

25/50/100 Master

The Master Captain’s License is required to captain any USCG inspected vessel, or vessels carrying 7 or more paying passengers. Larger tour boats, finishing boats, sailboats, and water taxis with more than 6 paying passengers on board require a Master License.

This license also allows you to captain uninspected vessels with fewer passengers. You don’t need to get a lower level license prior to this, or start at the lowest level. Your first license can be a 100 GT Master.

Similarly to the six-pack license, there are different Master licenses based on the size of the vessel, and the water you’re on.

To start, there are 25, 50, and 100-ton licenses. The 25-ton Master license qualifies you to captain vessels up to 25 tons. The 50-ton lets you captain 50-ton vessels. And the 100-ton lets you captain 100-ton vessels.

The license you qualify for depends on your documented sea days and the tonnage of the vessels you were serving on.

25 Ton Master = You have a minimum of 360 days on vessels less than 17 gross tons (GRT).

50 Ton Master = You have 180 days on vessels 26 GRT or larger, or 360 days on vessels 17 GRT or larger.

100 Ton Master = You have 180 days on vessels 51 GRT or larger, or 360 days on vessels 34 GRT or larger.

The Coast Guard will decide which license you’re qualified for based on your documented sea days on your license application. And if you get more sea time on larger vessels, you can always apply for an upgrade, so it’s best to focus on getting the license for the work you’re currently doing.

It only takes 90 days of additional sea service to remove tonnage limitations. For example, after 90 days of sea service, you can apply to upgrade from 50 Ton Master to 100-Ton Master. Note: The Coast Guard won’t automatically update this for you—you’ll need to apply for it.

Just like the OUPV, there are Great Lakes, Inland, and Near Coastal Master Licenses, and your qualification depends on the location of your sea days.

How big is a 25/50/100 Ton vessel?

A 25 GRT vessel doesn’t mean the vessel weighs 25 tons. There are specific formulas to measure GRT outlined in the Coast Guard’s Tonnage Guide .

To give you a general idea of the different vessel sizes:

• A 25-ton vessel can be 40-60 feet depending on how it's built.
• A 50-ton vessel can be 60-70 feet depending on the type of vessel and material
• A 100-ton vessel can be upwards of 200 feet, depending on its construction and uses

25/50/100 Master general requirements

In addition to the required sea days, there are general requirements for your Master License that are similar to the OUPV requirements. These include age, experience, character, physical health, citizenship, approved training, professional competence, a drug test, and more, including:

• Obtaining your TWIC card
• You must demonstrate an ability to speak and understand English.
• You must have at least 90 days of required service on vessels of appropriate tonnage or horsepower within the past 3 years of your application date.
• You must be at least 19 years old (21+ for ocean-going vessels).
• You must have had a physical done within the past 12 months.
• You must get a background check done.
• You must have a valid CPR and First Aid certificate .
• You must complete the appropriate USCG-approved course.

Master license endorsements

In addition to the USCG Master License, there are additional endorsements that qualify you for activities. These include the Assistance Towing Endorsement and Auxiliary Sailing Endorsement.

To operate an inspected (more than six paying passengers) sailing vessel, you need a U.S. Coast Guard auxiliary sail license endorsement attached to your Master License.

You’ll need at least 180 sea days on a sail or auxiliary sail vessel for a Sailing Endorsement onto a Master Inland/Great Lakes Captain’s License, and 360 sea days on a sail or auxiliary sail vessel to add the endorsement onto a Master Near Coastal License. You also need to pass a USCG-approved auxiliary sail course.

Both the OUPV and Master License can be endorsed for commercial assistance towing of disabled vessels—within the scope of the license.

No documented experience is required for the towing endorsement. You must pass a written examination or complete a Coast Guard-approved course demonstrating your knowledge of towing safety, equipment, and procedures.

The validity of the endorsements are the same as your license or MMC on which they’re included, and will be renewed with your MMC.

Captain’s Licenses Deciding Which License is Best for Me

What are the types of captain’s licenses?  

The two main captain’s licenses issued by the Coast Guard are the Operator of Uninspected Passenger Vessels, also known as the Six-Pack or charter boat captain’s license, and the 25, 50, or 100-Ton Master License. 

The  Six-Pack Captain’s License  allows the holder to carry up to six paying passengers plus crew on uninspected vessels up to 100 gross tons, hence the term six-pack. These are usually recreational vessels that are normally engaged in charter fishing, scuba diving, or tour cruises. 

The 25/50 or 100 Ton Master Captain’s License  allows the holder to operate inspected vessels as well as uninspected vessels. Any vessel that is authorized to carry more than six paying passengers must have on board a captain who holds a Master license. Ferry boats, harbor tour boats, whale watching, and water taxis are examples of inspected vessels. 

What endorsements can I add to my captain’s license?  

Two additional endorsements can be added to your license. The  Towing Endorsement  may be issued to those who hold a Six-Pack or Master license and would like to engage in assisting vessels for a fee. To commercially assist other vessels that may be aground, disabled, out of fuel, or experiencing some other malfunction requires an endorsement for commercial assistance towing. 

Licensed Masters or mates may also be  endorsed for sail or auxiliary sail  as appropriate. This endorsement authorizes the holder to operate inspected sale or auxiliary sailing vessels within the scope and limitations of their license. 

Whether you’re a sailor chasing the wind, a power boater in search of the next big fish, or a cruiser looking for the perfect sunset, earning your captain’s license will open the door to new opportunities. 

Which captain’s license should I get?  

The staff at Mariners Learning System recommends that you seek the highest-level license that you can qualify for. There are a couple of options, depending on your citizenship status and boating experience.

Watch our video to help decide which license to go for. 

Should I get an OUPV/Six-Pack or Masters license?  

If you are just looking to become a safer boater by gaining additional knowledge, then the  OUPV/Six-Pack  is the license that we recommend. 

If you are looking to use your license professionally, then we recommend that you consider skipping the OUPV/Six-Pack and go directly to the  Masters  level license. 

Which captain’s license should I obtain if I want to do ___?  

OUPV/Six-Pack  

• Fishing charter  
• Sailing charter  
• Scuba diving boats  
• Tour cruises   
• Lower insurance rate   
• Take 6 or less paying passengers out on an uninspected vessel   
• Operate uninspected vessels up to 100 gross tons   
• Education and safety alone, do not plan on using it professionally   

25/50/100 Ton Masters  

• Ferry boats  
• Harbor tour boats   
• Sailing schooners   
• Dive boat  
• Whale watching boat  
• Water taxis    
• Take 7 or more paying passengers out on an inspected vessel  
• Operate uninspected and inspected vessels 

To learn more, see our one-minute guide to finding out  which license is best for you . 

Which captain’s license should I get as a recreational boater?  

Most recreational boaters choose to get the  OUPV captain’s license , also known as the Six-Pack. This license is not required for recreational boaters, but many boaters with no intention of operating a commercial vessel go for their OUPV captain’s license because they want to brush up on safety and navigational skills. Plus, people like the pride of knowing they’ve achieved the designation.  

You can also go for your  Master captain’s license  as a recreational boater, and you can achieve this license without first holding an OUPV/Six-Pack license. 

Do I need a captain’s license to be a fishing guide?  

If you want to be the captain of a fishing boat with paying passengers, you need a USCG captain’s license. To be a fishing guide for up to six passengers, you can obtain an  OUPV/Six-Pack  captain’s license. To be the captain of a ship with more than six paying passengers, a  Masters  license is necessary. 

What are the license requirements to become a Sea Tow captain?  

The minimum licensing requirement for Sea Tow is you must have an  OUPV/Six-Pack  license with a  Towing Endorsement . However, many of the Sea Tow franchises require a  Master  level license with a Towing Endorsement.  

If the Sea Tow franchise is using a vessel of 26 feet or more, they will require you to get a Master level license with a Towing Endorsement.  

We recommend going for the Masters + Towing Endorsement, if you qualify, to open up more job opportunities for you. 

Which captain’s license is need to drive a tugboat?  

Mariners Learning System only offers courses that will help you get a captain’s license to have paying passengers aboard. The  Towing Endorsement  is added onto the captain’s license to assist disabled passenger vessels; example- malfunctioning equipment or ran out of fuel.  

We recommend calling the National Maritime Center at (888) 427-5662. They may be able to give you more information on what you will need and where to go for a tugboat license.   

How do I become a tour boat captain?  

You can work as the captain of a commercial tour boat if you acquire a USCG-approved captain’s license. For small tours with up to six paying passengers, the  OUPV/Six-Pack  license is enough. For tours with more than seven or more passengers, you will need a  Master  captain’s license. 

Networking and word of mouth are usually the best methods for landing a job as a tour boat captain. To get your foot in the door, you can start your career in the marine industry by working as a mate. This will give you invaluable local knowledge and help you get familiar with the ports and marinas in your area. 

What kind of license do I need for a sailboat?  

The  OUPV/Six-Pack license  is good for both power and sail. For those who want to run sailboats with seven or more paying passengers, a  Master level captain’s license  with a  Sailing Endorsement  is required. 

What is the difference between a sailboat captain’s license vs. ASA and US sailing courses?   

The American Sailing Association (ASA) and US Sailing Association both provide sailing certification programs. These programs are different from taking a course for the USCG sailing endorsement that can be added to your captain’s license. The Mariners Learning System  auxiliary sailing endorsement online course  will prepare you for this certification whereas ASA and US Sailing courses will not. 

How can I tell how many paying passengers I can have aboard, and which license I’ll need?    

If it is an inspected vessel with a Certificate of Inspection (COI) for more than 6 paying passengers, you will need a  Masters  license. If you do not have these, then you will not be able to take out more than 6 paying passengers. 

Generally, boats with COI's are built for specific purposes, like water taxis and duck boats. The COI indicates how many paying passengers and the level of Masters license that is required.  

Most recreational boats, like house boats, are uninspected without a COI, and the  OUPV/Six-Pack  is needed to operate commercially.

How Big is a 100 Ton Boat? – Size, Capacity & Features

Written by J. Harvey / Fact checked by S. Numbers

There are a load of reasons why folks ask, “How big is a 100-ton boat?” Since it’s about size, I will answer this question based on tonnage, which measures a boat’s overall size based on volume.

The size of a 100-ton vessel varies a lot, but it’s generally accepted that 65 feet is the minimum. Such vessels also typically have two stories or more. Remember that internal volume isn’t the sole indicator of size. The length overall (LOA), beam, and draft are needed to get the full picture.

Table of Contents

1. Size in terms of length, width, and height

2. capacity and features, 3. factors that influence the size of a boat, 4. comparison to other boat sizes, types of boats that can be classified as 100-ton boats, dimensions of a 100-ton boat.

One thing is clear when pinpointing the dimensions of a 100-ton ship: it’s fairly large.

But ultimately, every ship has a different LOA, beam, draft, etc., which is why we often have to manually measure each vessel to truly know its exact dimensions and, in turn, size.

Either that or you need to consult the actual boat designers and manufacturers about the exact dimensions of the boat. We can’t use gross tonnage solely to get the boat’s perfect measurements, as it only refers to the ship’s overall internal volume.

To further prove that gross tonnage isn’t directly proportional to vessel size, just observe the world’s biggest watercraft by gross tonnage:

• As you can see, smaller vessels also have high gross tonnage values. That may mean they’re designed to maximize their cargo-carrying capacity.
• On the other hand, there are also larger ships with relatively lower gross tonnage. That could indicate its designers put more emphasis on internal volume rather than carrying capacity.

The USCG Master Licence does provide us with clues, though. Once you complete the 100-ton Master requirements, they explicitly state that you can now handle vessels of 65 feet and larger.

That is clearly the sole set parameter we can ever have in terms of tonnage with regard to size. It’s infinitely easier to calculate the gross tonnage using the boat’s dimensions which you have manually measured yourself or as indicated in the boat’s design plans.

After all, we can calculate gross tonnage by using the formula:

Gross Tonnage = L × W × H × Block Coefficient

Another formula we can follow is the more standard Gross Tonnage (GT) = K1V (with V being the volume of enclosed space on the ship and K being 0.2+0.02log10(V)), but it only applies to larger ships like cargo and passenger vessels.

And, even after we’ve calculated the exact gross tonnage, we can only ever estimate the size, which can still be larger or smaller, as proven by the link to the table shared above. 

So, we’ll ultimately have to rely solely on the indicated length for a 100-ton vessel to get an idea of its size, especially if we don’t have a vessel to measure or the exact dimensions aren’t readily accessible. Moreover, length is arguably the most important parameter when classifying boats in the first place.

That said, if you insist on getting a rough estimate as to width and height, then know that a 100-ton boat can have beams 16 to 25 feet wide, whereas its height is at least 2 stories.

To get the capacity of a 100-ton boat, we need to consider the fact that 1 net ton is equal to 100 cubic feet. Assuming a 100 gross ton boat also has a net ton of 100, its cargo volume would therefore be 10,000 cubic feet. Its average displacement should be around 224,000 pounds.

Its features will inevitably vary as it can be any kind of large boat.

A yacht of this capacity may have more amenities, a more sizable dining or lounging area, and more rooms.

A typical tugboat will have rotating azimuth units, and they generally have powerful engines, too.

On the one hand, yachts will have wider viewing decks, more seats, restrooms, and other possible amenities.

• Intended purpose

A kayak may be designed to be shorter to make it more maneuverable and portable, while a passenger ship will inevitably be larger to safely accommodate as many people, crew, and amenities as possible. You typically require a bigger boat when doing offshore fishing than inshore, too.

On the topic of shipping, containerships often optimize their carrying capacity. Usually, their size, capacity, and categorization are determined by their TEU (Twenty-foot Equivalent Unit) capacity. It’s termed as such because 1 TEU is equivalent to one 20-foot container.

Ultra-large container vessels have more than 14,500 TEU, which means, yes, they can fit 14,500 boxes of that specific size.

• Estimated length of the trip

Lengthy journeys tend to require more amenities and sturdier construction to withstand unexpected rough conditions. This results in a larger boat size than vessels intended for short trips.

• Engine power

Vessels designed to reach a higher speed typically require bulkier engines, which in turn will call for a larger boat to accommodate them.

• Other considerations

Manufacturers take note of boaters’ different storage options, budgets, dock spaces, and trailering options when deciding the sizes of boats they create.

100-ton vessels are larger than most recreational boats, but may be smaller than your average commercial fishing vessel or cruise ship. The closest size would likely be that of a standard tugboat.

That already means a 100-ton boat is bigger than most dinghies, PWCs, kayaks, motorboats, and even sailboats.

Interestingly, it’s entirely possible to build a whopping 230-foot passenger vessel and keep it at or even below 100 gross tons with the right strategy (by, for example, knowing where to place fuel cells and utilizing tonnage openings).

So, yes, we shouldn’t fully consider it impossible for a 100-ton boat to rival even the world’s largest cruise ships and container ships in size. That should hammer the point that tonnage can only be connected to size up to a certain point.

When pinpointing the types of boats that you can classify as 100-ton vessels, you need to be able to distinguish the ones that relate to weight more from those that connote capacity.

For example, the 100 Yacht by Sunseeker has been referred to as a 100-ton yacht because it displaces that much water, and not necessarily because it has 100 gross tons. Again, “tonnage” is different from displacement tons! We need to be looking at gross tonnage (GT) if size is the main concern.

If we’re going by size estimations and typical applications and purposes alone, below are the types of boats that can be classified as 100-ton vessels. Again, note that the length, width, and depth are rough estimates and not definitive figures.

The answer to “How big is a 100-ton boat?” will always be that it starts at 65 feet. From there, your design decisions will greatly affect the final shape and size of the vessel while still maintaining a gross tonnage of 100.

There’s a lot of confusion when it comes to this topic, I admit. This only underscores the importance of widening your maritime knowledge further while honing your seamanship at the same time.

25-100 Ton Boat Hoists Features

• Remote Diagnostics

Our remote diagnostics allow free support around the globe. Experienced factory technicians are able to perform the diagnosis, identify a faulty part and/or modify program parameters without having to make a trip to your site.

• Sling Adjust

The BFMII models feature standard powered sling adjust to maximize capacity and optimize the diversity of vessels you can lift. The operator has full control of this function and can adjust each sling's position to improve load balance or to avoid stabilizers and other sensitive elements on the hull.

• Formed Steel Structure

Reduces fatigue and extends the life of your machine with a beam-formed structure. Rounded edges don't allow stress to concentrate in the corners providing a more durable structure for more heavy-duty work.

• PPG Siloxane Paint

Increase life and reduce corrosion with this 2-step PPG Paint process. A zinc-enriched epoxy primer and polysiloxane topcoat provide superior performance proven in the most difficult marine environments.

• Intelligent Readout System

The intelligent readout provides multiple outputs including general engine performance, real-time measurements of machine operations, oil level/temperature and pump pressures. It also allows for performance troubleshooting and complete systematic control.

• Industrial Tires

Our industrial tires provide the highest level of durability with an abrasion-resistant additive to withstand different style terrain.

• Greaseless Pivot Trunnion

The pivot trunnion allows the machine to articulate over uneven ground without adding stress to the structure. The use of a greaseless, wear-resistant bushing means less maintenance and eliminates the chance of grease falling on a boat.

• Operator Cab

Operator cabs are standard on all Marine Travel BFMII boat hoists. The controls are direct to valve and hydraulically control all functions as well as act as a backup to the radio remote option.

• Chine & Keel Pads

Built to protect, sustain and withstand various temperatures and climates, further extending the life of your slings. Made with thick reinforced rubber or vinyl to protect the sling from sharp edges and the additional weight helps to sink the slings and keep them from rolling when a boat floats in.

• Hydraulic Fluid Leak Protection

Stainless steel tubing, O-Ring face seal hydraulic fittings, and cordura hose covers are all used for added protection against hydraulic leaks to keep fluid off boats and out of the water. Our 2205 stainless tubing resists corrosion in the harshest marine environments and cordura hose coverings prevent the elements from prematurely deteriorating the hoses.
