sailboatdata laser

The Laser is the world’s most popular adult racing class boat. True to box one design standards, each Laser in the world is identical ensuring the best sailor on the water wins the race, not the boat. The Laser is a challenging boat that rewards athleticism, subtle steering and trimming techniques, as well as the tactical excellence of the sailor. The Laser has been raced by young and old alike from the Club level all the way to the Olympics. It comes in 2 different hardware versions XD, for racers and the ones looking for a more thrilling sailing experience and the Race, more suitable for the leisure sailors and club racing. Each hardware version has 3 rig possibilities, the Standard , the Radial and the 4.7  for the heaviest/more athletic to the lighter and younger sailors.

The world’s premier racing dinghy. The Weekender (name of the first prototype), with “TGIF” (Thank God It’s Friday) on the sail was designed in 1969 and quickly revolutionized the racing world with its speed and simplicity. It was called Laser in November 1970 and the production started the same year. It was launched at the New York Boat Show, its uniform design and affordable price attracted sailors and 144 Lasers were sold. Laser sails were identical due to modern laser cutting thus setting a standard for future racing classes. Today this timeless design is by far the most popular adult and youth racing boat worldwide. It is raced by many of the world’s top sailors and has been an Olympic class since 1996. The Laser’s full size rig rewards athleticism and is best for heavier, more experienced sailors, but it can easily be converted to a Radial or 4.7 by changing just the sail and bottom spar. When you race a Laser, one hull goes a long way. Just changing the lower mast and sail, you can convert any boat from Laser to Radial to 4.7. The advantage of this interchangeable formula is that you can easily switch boats as you become older, heavier or more experienced. Each rig helps you prepare for the next, so you get a step-by-step progression that can take you all the way from a beginning racer to World Champion!

The Laser has 2 hardware versions and 3 different rigs. Each uses exactly the same hull and foils, by lower mast and sail will make it suitable for a wide variety of sailors. This offers a unique step-by-step progression that makes it easy to switch models as a sailor change in age, ability or weight.

Two hardware versions to fulfill every sailor needs

• XD – For the ones looking for more performance – Carbon Fibre Upper Mast – Carbon Fibre Tiller and Extension – LaserPerformance Vang
• Race – For Recreational Sailing or Club Racing – Aluminium Upper Mast – Aluminium Tiller and Extension – Holt Vang

Three rig versions to suit every sailor

• Standard – 7.1sqm sail for heavier and more athletic sailors
• Radial – 5.1sqm sail for women, and lighter sailors
• 4.7 – 4.7sqm for youth and lighter females

The Laser is a true sailing phenomenon

With nearly 200,000 boats in 140 countries, it is clearly the world’s most popular adult and youth racing sailboat. Each year the Laser Class runs more races worldwide than any other class. And it’s still going strong! For almost four decades, the Laser has been a sailing success story. One reason is the boat’s sheer simplicity. From its very beginning, the Laser has offered an uncomplicated way for sailors to experience the joy of sailing and the thrill of competition. Many other qualities combine to make the Laser a legendary performer.

Effortless design

The Laser was created to get sailors on the water with minimal fuss. It has a lightweight hull that’s easy to carry and cartop. The two-part free-standing mast and sleeved sail make the boat easy to rig. And the simple layout means sailing is a breeze.

Strict One Design

The Laser is one design boat like no other. The class association is very strong and has strict class rules, so every Laser around the world is identical. This means races are won by sailing ability, not by equipment advantages.

Interchangeable formula

The Laser comes in three distinct models – the full-rig Laser, Laser Radial and Laser 4.7. Each uses exactly the same hull and equipment, except the sails and bottom spar can be changed to fit a wide variety of sailors. This offers a unique step-by-step progression that makes it easy to switch models as a sailor change in age, ability or weight.

Racing pedigree

Because Lasers are simple and identical, they provide exciting competition and a great chance to develop racing skills. Many of the world’s top sailors come through the Laser ranks, and both the Laser and Radial are current Olympic classes. No sailor is too inexperienced or too advanced to race a Laser. That’s why Lasers last a lifetime.

Superb value

The Laser’s simplicity, popularity and one design nature make it very economical. The Laser Class limits and controls go-fast extras, thus the boat will never be outdated, which explains why Lasers have such a high resale value. Whether it’s a local club race or the World Championships, every Laser has exactly the same chance of winning. And a young sailor can go all the way to the top of the sport in the same hull. That is Laser’s simple formula for success.

Privacy Overview

It should be borne in mind that some of the low numbers are a result of a single boat being sailed by an exceptional sailor and it is highly unlikely that an average club sailor could sail to these numbers. A case in point is the 117 that our Rep. O.J.Young in Houston has been given. O.J. is not your average sailor having won SORC, the J24 Mid Winters, and a host of other championships too numerous to mention. In his first outings in the Laser 28 he won the Clear Lake R.A. December Series and tied for first in the Houston Y.C. Turkey Day. I am confident however, that over a season the Laser 28 cannot sail to this number. An educated guess after sailing the prototypes and the production boat for four years is that the boat will eventually settle down with a 1 26. (Note: Just before printing, the Galveston Bay Cruising Association raised the Laser 28 to 120.) News Snippets from Around the Country

Robert Dunkley of Nassau, Bahamas, took delivery of his boat on Saturday morning in Ft. Lauderdale, put the sail up and sailed straight to Nassau with two friends. (That’s putting a lot of pressure on your builder, Robert!) They sailed through 30 knot north winds in the Gulf Stream with 10-15 foot waves. When asked if there were any problems, two surfaced: the Compass gimbal had been broken in transit from Montreal and when they arrived in Nassau “the rigging was slack”! (This would be normal after the first few times of even normal sailing as all toggles, shroud attachment recess, etc., bed in.) Please, don’t anyone else do that!

Judy and Frank Button from Vancouver sailed their Laser 28 to a fourth straight win in the IYC winter series. Judy, the skipper, has only been racing two years having raced their Tanzer 7.5 for the first two years. Boats in the fleet include: Dash 34, C & C 33, C & C 34, Mirage 33, Reliant 37. Frank and Judy are moving back east to Grimsby, Ontario and plan on attending the Quebec Open in June.

Paul Kaplan, well known sailor on San Francisco Bay and our Rep for that area, singlehanding his Laser 28 on only its fourth outing sailed to a first in class and first overall in a 38 boat fleet in San Francisco’s Singlehanded Sailing Society’s “Three Bridge Fiasco Race”. Paul’s only comment "The boat is outstanding!" His wife, Chris, meanwhile, sailed the Laser 28 with an all girl crew to third overall in their Women’s Racing Association winter series.

Nearly 50 percent of the boats sold so far have been sold with trailers. At $2,450 US or $3,000 Can. the trailer pays for itself quickly, especially if the owner picks up his own boat. Add to this the saving of a yard cradle and the ability to store the boat on one’s own property or in some other non-revenue location and it pays for itself in a couple of years.

The Laser 28 is the only true one-design racer/cruiser on the water today. It is the only racing/cruising class with one design sails where the test is not going to be who has the latest cut, but rather who is the best sailor. The sails were developed over five years by Hans Fogh of North Sails, Olympic Medalist and World Champion, working hand in hand with Bruce Farr and myself as we slowly perfected the rig. Not only are they perfectly cut for the Laser 28’s simple, lightly tensioned rig, they use cloth materials selected to last for the longest possible time (one of the final prototype mains is going into its fourth season). Thirty, identical Laser 28’s at CORK with identical sails will be a first in yachting. (The IOD is the only other keel boat to our knowledge that has one-design sails but it does not qualify as a cruising boat.) Good sailing! Ian Bruce

The Laser 28 is a 28.41ft fractional sloop designed by Bruce Farr and built in fiberglass by Performance Sailcraft between 1983 and 1990.

The Laser 28 is a light sailboat which is a very high performer. It is stable / stiff and has a low righting capability if capsized. It is best suited as a racing boat.

Moscow concert attack: More than 60 reported dead; ISIS claims responsibility

This live blog has ended. For the most recent updates, please click here .

What we know about the Moscow concert attack

• Men in camouflage broke into a Moscow concert hall and opened fire, shooting an unknown number of people, Russia’s prosecutor general said.
• The terror group ISIS has claimed responsibility but did not provide proof of the claim, which was made on ISIS-affiliated news agency Amaq on Telegram.
• Russia's Investigative Committee said that more than 60 people are dead after the attack at Crocus City Hall. Officials have said more than 100 others were injured.
• A fire also started inside Crocus City Hall, a large concert venue northwest of central Moscow. Firefighters have evacuated about 100 people from the basement of the building and efforts are underway to rescue people from the roof, Russian emergency officials said.
• Russia officials said they were investigating the attack as a terrorist act.
• A popular rock band was scheduled to play what appeared to be a sold-out show at the venue, which has a maximum capacity of more than 9,000 people.

Three children among those killed, state media reports

Chantal Da Silva

Three children were among the more than 60 people killed in yesterday's attack at Crocus City Hall, Russian news agency RIA Novosti reported, citing the Russian Ministry of Health.

Officials have warned that the death toll connected to the deadly incident may increase as the investigation continues.

Xi sends condolences to Putin

Chinese President Xi Jinping sent condolences to Russian President Vladimir Putin on Saturday after a deadly shooting at a concert hall near Moscow, saying China opposes all forms of terrorism and strongly condemns terrorist attacks.

China firmly supports the Russian government’s efforts to maintain national security and stability, Xi said, according to CCTV state television. 

Moscow bloodshed comes two decades after some of worst attacks in Russia

Phil Helsel

The shooting attacks in Moscow are the latest in a series of deadly terror attacks in the country since the 2000s.

In 2004, militants from Chechnya and elsewhere took hostages at a school in Beslan in southern Russia.

The militants demanded a withdrawal from Chechnya. Hostages were kept in a gymnasium, and 334 died — half of them children — when gunfire and explosions erupted when it was stormed. Hostages’ families were critical of the rescue operation. Russian prosecutors later cleared authorities .

Two years prior, in 2002, Chechen separatists attacked the Dubrovka Theater in Moscow and took more than 700 people hostage. Russian forces used gas, and 129 hostages died. The attackers were killed.

More recently, in 2017 a suicide bomber from Kyrgyzstan killed 15 people as well as himself in an attack on a St. Petersburg subway. In 2013, two bombers killed a combined 34 people in attacks on a railway station and a trolleybus in Volgograd.

The group Islamic State, also known as ISIS, claimed responsibility for the attacks Friday at the Crocus City Hall venue.

Putin wishes victims well, deputy prime minister says

President Vladimir Putin is thinking of those injured in today’s attack and thanked doctors, a Russian government official said according to state media.

State media TASS reported that “Putin wished all those injured in the emergency at Crocus City Hall to recover and conveyed his gratitude to the doctors, Golikova said,” referring to Tatiana Golikova deputy prime minister for social policy, labor, health and pension provision.

More than 60 dead, and death toll could grow, Russian agency says

Russia’s Investigative Committee said Saturday that more than 60 people have died in the attack, and warned the number may increase.

“The bodies of the dead are being examined. It has been previously established that more than 60 people died as a result of the terrorist attack. Unfortunately, the number of victims may increase,” according to the Investigative Committee, which is a federal state agency.

Russia's Ministry of Internal Affairs and the security agency FSB are continuing to investigate, the committee said in a statement, and weapons and ammunition have been found.

U.S. warned Russia about planned terrorist attack in Moscow, NSC says

Monica Alba

The United States shared information about a potential terrorist attack in Moscow with Russia’s government earlier this month, a spokesperson for the National Security Council said.

The U.S. Embassy in Russia on March 7 warned U.S. citizens to avoid crowds and said it was monitoring reports that extremists might attack large gatherings in Moscow.

“Earlier this month, the U.S. Government had information about a planned terrorist attack in Moscow — potentially targeting large gatherings, to include concerts — which prompted the State Department to issue a public advisory to Americans in Russia,” NSC spokesperson Adrienne Watson said.

“The U.S. Government also shared this information with Russian authorities in accordance with its longstanding ‘duty to warn’ policy,” Watson said.

Putin recently dismissed ‘provocative’ warning about potential attacks

In remarks that aired three days ago, Russian President Vladimir Putin accused the West of “provocative statements” about potential terror attacks in Russia, and dismissed them.

“I’ll remind you of recent, let’s say directly, provocative statements of certain official Western structures about potential terror attacks in Russia,” Putin said.

“All of this looks like obvious blackmail and an attempt to intimidate, destabilize our country,” he said before the state security agency FSB.

Putin in those remarks did not specify a country or warning. The U.S. embassy in Russia on March 7 warned U.S. citizens to avoid crowds .

“The Embassy is monitoring reports that extremists have imminent plans to target large gatherings in Moscow, to include concerts, and U.S. citizens should be advised to avoid large gatherings over the next 48 hours,” the U.S. embassy warned.

Guards at concert hall didn't have guns, state news says

The Associated Press

Guards at the concert hall didn’t have guns, and some could have been killed at the start of the attack, Russian media reported.

Some Russian news outlets suggested the assailants fled before special forces and riot police arrived.

Reports said police patrols were looking for several vehicles the attackers could have used to escape.

U.S. had been gathering intelligence that ISIS could attack Russia

Ken Dilanian

The U.S. had been gathering intelligence for months that ISIS could mount a mass casualty attack in Russia, two U.S. officials confirmed to NBC News.

That information led to a March 7 warning issued by the U.S. embassy in Russia about possible extremist attacks, including at concerts, urging people to stay away from large gatherings, one of the officials said.

That official said the claim of responsibility today by ISIS appears to be genuine, though no final assessment had been made about who was responsible.

Some Moscow concertgoers filmed events as they unfolded Friday night, when gunmen opened fire inside a theater and people ran to take cover in fear for their lives.

Witness says gunfire was first thought to be construction noise

A witness to today’s armed attack on Moscow’s Crocus City Hall told a state news agency that they first mistook the gunfire for sounds of an installation being dismantled.

“First, we started hearing typical loud pops, but it was impossible to understand that they were gunshots. We thought that something was falling, as exhibitions were being dismantled at that moment, and someone seemed to be dropping something large,” Mikhail Semyonov told TASS .

“Then, the bangs were getting more and more frequent. Suddenly, there was a scream, and the bangs started to be heard as bursts. Then it became clear that it was shooting,” he said.

ISIS claims responsibility for attack but does not provide proof

The terror group Islamic State has claimed responsibility for the attack in Moscow.

The group, also known as ISIS, did not provide any proof of its claim, which came from ISIS-affiliated news agency Amaq on Telegram.

The group’s members have carried out a number of terror attacks, including the 2015 attacks in Paris that killed 130 people.

Children among the victims, Russia's children commissioner says

Yuliya Talmazan

Russia’s commissioner for children’s rights, Maria Lvova-Belova, said children were among the victims of tonight's attack.

"Information about their condition is regularly updated," Lvova-Belova said on Telegram. "Any additional assistance will be provided immediately."

She later told Russia 24 TV channel that at least two children had been injured, including one boy with a gunshot wound.

Earlier, Russian officials released a preliminary casualty toll of at least 40 people dead and more than 100 injured.

France, U.K., Germany condemn attack

Officials from France, the U.K. and Germany were among those who expressed their condolences to the victims of the attack at the Crocus concert hall.

"The images of the terrible attack on innocent people in Crocus City Hall near #Moscow are horrific," Germany's Foreign Office said on X . "The background must be investigated quickly. Our deepest condolences with the families of the victims."

"We condemn the terrorist attack in the Crocus City Hall near Moscow," the U.K.'s embassy in Russia said . "This is a terrible tragedy."

Meanwhile, France's foreign ministry called for "full light" to be shed on "these heinous acts."

Public events across Russia called off after attack

Several regional leaders across Russia, including in the annexed Kherson region of Ukraine, have canceled public events this weekend over security considerations after the deadly concert attack in Moscow.

Shortly after the attack, Moscow Mayor Sergey Sobyanin canceled all sports, cultural and other public events in Moscow this weekend. State news agency TASS also quoted Russia's cultural ministry as saying that mass and entertainment events in federal cultural institutions have been canceled in the coming days.

Zelenskyy adviser speaks out about attack

President Volodymyr Zelenskyy’s adviser denied that Ukraine was involved in the deadly Crocus concert hall attack.

“Ukraine certainly has nothing to do with the shooting/explosions in the Crocus City Hall (Moscow Region, Russia),” Mykhailo Podolyak wrote on X. “It makes no sense whatsoever.”

No evidence has emerged to suggest Ukraine may have been involved, but Ukrainian officials may be trying to pre-empt accusations, as some Kremlin hawks have already started pointing at Kyiv. 

Asked whether the shooting was at all tied to the war in Ukraine, U.S. National Security Council spokesperson John Kirby said: “There is no indication at this time that Ukraine, or Ukrainians, were involved in the shooting, but again, this just broke. We’re taking a look at it, but I would disabuse you at this early hour have any connection to Ukraine.”

Videos posted to social media appear to show chaos inside Moscow's Crocus City Hall during and after a terrorist attack.

Some videos include what sound like gunshots and show men with rifles, as concertgoers frantically try to exit the venue.

State Department issues warning to Americans in Moscow

Jason Abbruzzese

The State Department said that the U.S. Embassy in Moscow is aware of the terrorist attack on Crocus City Hall and that U.S. citizens should avoid the area and follow the instructions of local authorities.

"The U.S. government’s ability to provide routine or emergency services to U.S. citizens in Russia is severely limited, particularly in areas far from the U.S. embassy in Moscow, due to Russian government limitations on travel for U.S. embassy personnel and staffing, and the ongoing suspension of operations, including consular services, at U.S. consulates in Russia," the State Department said in a message posted to its website .

'What a nightmare in Crocus,' Widow of opposition leader Alexei Navalny condolences about concert attack

Yulia Navalnaya, the widow of Russian opposition leader Alexei Navalny who died in prison last month, expressed her condolences about the attack Friday.

"What a nightmare in Crocus," Navalnaya wrote on X. "Condolences to the families of the victims and quick recovery to the injured. Everyone involved in this crime must be found and held accountable."

U.S. warned of imminent Moscow attack by ‘extremists,’ urges citizens to avoid crowds

Patrick Smith

U.S. citizens in  Moscow  had been warned to avoid large gatherings earlier this month because of heightened fears of a terrorist attack.

The U.S. Embassy in the Russian capital said it was “monitoring reports that extremists have imminent plans to target large gatherings in Moscow, to include concerts, and U.S. citizens should be advised to avoid large gatherings over the next 48 hours.”

U.S. citizens should avoid crowds, monitor local media for updates and “be aware of your surroundings,” it said in a brief  online update .

Sunfish is a 13 ′ 10 ″ / 4.2 m monohull sailboat designed by Alexander Bryan/Cortland Heyniger/Carl Meinart and built by Pearson Yachts, Alcort, AMF Corp., and LaserPerformance starting in 1952.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Although the earliest models were built of wood and offered as kits, the fiberglass version, first introduced in 1960, became the most popular recreational sailboat in history. As a result, there were many imitators.

Sunfish Builder Chronology 1952 - 1969 Alcort, Inc. (founded 1945) 1969 - 1986 AMF 1986 - 1988 Loveless & DeGarmo, dba, Alcort Sailboats Inc. 1988 - 1991 Pearson Yacht Co. 1991 - 1997 Sunfish/Laser, Inc. 1997 - 2007 Vanguard 2007 - Laser Performance Change in class rules permitted a new, slightly deeper daggerboard in the mid-1990’s.
