sailboat power consumption calculator

The relationship between power and current is expressed as: Power (W) = Current (A) x System Voltage (V) To derive amps from watts, simply transpose this equation and divide the wattage by the system voltage. For example, a 6 watt navigation light bulb in a 12 volt system will draw 0.5 amps - which, if it's switched for ten hour each day when ...

calculate your power consumption. download now. Step 2 - Energy supply on a sailboat. A big battery bank has no use if you can not charge them. The second step in designing the electrical set-up on a boat is to define your electrical generators. The electrical needs we calculated above are all maximum usage scenarios.

Marine Power Usage. The chart below shows examples of energy consumption of various equipment. The current (amps) is multiplied times the amount of hours per day is used to determine the Amp Hours per day of energy that is consumed. These values are based on a 12 V DC nominal system. If selected items in the above charts do not match to your ...

Here's our at anchor list as a starting point, note that you need to know amps per hour AND an estimate of how many hours you use the item to calculate daily amp usage. LED Anchor Light .25/hour X 10 hours = 2.5 amps/night. Adler Barber Cold Plate - Refrigerator & Freezer 6 amps/hour X 24 hours = 144 amps/day (theoretically it cycles on ...

Instructions For Using The Vessel Energy Usage Estimator Worksheet. . Open worksheet on your PC or tablet. You can use the default amperage rating for the equipment listed or if you have amperage ratings of the specific equipment on board your vessel, change the amperage listed in the worksheet. Fill in the hours used for each item over a 24 ...

Energy Calculator. Think of your system as the combination of three different calculations: Energy generation from solar, wind turbine, generator, and/or alternator. Energy storage to/from the battery bank. Energy draw to the system demands. Each system needs to be sized appropriately for your application, which starts with the demand you ...

The Daily Current Draw Calculator Calculation Sheet has intentionally been left unlocked in order that you may enter the current draw of each of the appliances on your boat, together with the daily periods that you have them turned on.. Current draw: The appliance amps currently entered on the sheet are notional. The most accurate way of establishing actual current draw on your boat is to turn ...

My power consumption is the tiller pilot (I calculate between use and standby it will consume about 27 amps per day), the Garmin 441s (I calculate 5.76 amps per day), and the stereo (about 20 amps per day). This is running them for 8 hours. Total power consumption for these devices would be around 52.64 amps per day, according to my calculations.

This makes the calculation of amount of available energy easy for the mariner. ... on average, the boat will use about 5000 watt.hrs of energy per day - this is excluding air conditioning. This makes the math really easy - the 3,500 watt.hr Lithium-Ion battery above fully charged would provide 3500/5000 = 70% of the daily requirement ...

Note - enter power at 12V or 120V but not both (one column is zero) Total amp-hrs used per 24 hr Sailboat power management calculator wh Note 1. Battery voltage is assumed to be 12.3 volts Note 2. If watts are entered at 120VAC, it is assumed

Take the daily corrected total loads in watt-hours from your load calculation. 1000: 1000: 3: Divide line 2 by line 1. This is the number of watts we need to generate per hour of full sun. 400: 200: 4: Find actual power produced by your selected module and enter here.

It is necessary to realise an inventory of electrical material, to check the operating power (Watt) for each device and to estimate the utilisation time for each equipment during 24 hours. ... (10W x 3 hours). Electricity consumption and navigation mode. The sailboat equipments and the necessary electricity vary according to the navigation mode.

Although smaller units have a fairly low draw of perhaps 200 milliamps, some larger models can pull up to 1.5 amps, even in standby mode. On a passage your VHF is on twice as long as normal—24 hours instead of 12—so you have to keep that in mind. That said, there's not much you can do about consumption, except getting the most energy ...

The boat cost of ownership calculator includes a boat loan calculator, estimates boat financing, boat insurance average cost, boat maintenance and docking costs. ... rate is calculated based on the data provided that depends on boat size, type (sail/power), days of use, average hours spent cruising per day. Gas and diesel prices are updated in ...

The boat is a Lagoon 420, ... Raymarine pilot power consumption has two elements - continuous (milliamps) ... is easier to figure an average power consumption equal to half the peak power rating of the drive motor for the 24 hour calculation for a "bad case" of power consumption. You will then be well under 360 Amp-hours for 24 hours. 26-04 ...

Part 1, Select A Boat From The Database: When you select a boat, its parameters appear below in Part 2. Choose a type of boat: Select one boat in each column above, and press to compare. Part 1B, Enter Measurements For Your Boat: Note that length overall, length of waterline, and beam are in feet, displacement in pounds, and sail area in square ...

This could look like this: when the yacht is disconnected from shore power, after about ten to 15 minutes the voltage/volt of the consumer battery should be read and noted. Depending on the battery type, this voltage/volt may be between 12.2 to 14.4 volts - value of the "full charge" of the batteries.

And a meter alerts you to potential problems. "If the average draw on your boat's electrical panel is 15 amps while under way, and all of a sudden the meter is reading 25 amps, you know something is up," Laska says. "A bilge pump might be stuck on, or a freshwater pump's diaphragm might have popped.". Sherman recommends the VSM 42 ...

ABYC Standard E11 proposes a way to do DC load calculations for boats. The results of the basic load calculation can be used to determine the amp rating for switch panels. The data collected can then be used to calculate daily power consumption and ultimately the results can be used as a way of calculating battery size. The first part of the ...

It takes into consideration "reported" sail area, displacement and length at waterline. The higher the number the faster speed prediction for the boat. A cat with a number 0.6 is likely to sail 6kts in 10kts wind, a cat with a number of 0.7 is likely to sail at 7kts in 10kts wind. KSP = (Lwl*SA÷D)^0.5*.05.

To navigate through this maze, use this formula to estimate your boat or engine's fuel consumption: GPH = (specific fuel consumption x HP) / Fuel Specific Weight. Weight: Gas = 6.1 lb. per gal. Diesel = 7.2 lb. per gal. The key to unlocking maximum horsepower lies in these formulas, optimized for the engine's peak performance at wide-open ...
