You then calculate the predicted speed by using the formula.

Boat power usage calculator. You can also calculate the minimum circuit breaker size for the given load. 22 rows Use this Boat Horsepower Calculator to estimate the power required to efficiently move. MerCruiser - Cummins - Volvo Penta Diesel Crusader - Mercury - Evinrude - Honda Marine - Yamaha Marine - Suzuki Marine - Tohatsu - Johnson - Outboards.

You can use this boat propeller calculator to determine one of five variables. Determine the correct diameter and pitch of a propeller for any given vessel and engine. To apply these formulas to your boat plug in its horsepower rating and multiply it by the specific fuel consumption average then divide the product by the fuel specific weight Formula To Estimate Maximum Engine Fuel Consumption Gallon Per Hour GPH specific fuel consumption x HPFuel Specific Weight Constants Gas Diesel.

Pitch inches 1215223 speed reductionRatio RPM max. Now that we have the nautical miles we need to know the engines power the hp and the real engine consumption of the boat we rent to have the actual yacht fuel calculation. The energy E in kilowatt-hours kWh per day is equal to the power P in watts W times number of usage hours per day t divided by 1000 watts per kilowatt.

GPH MPG LPH KPL Miles per Gallon - Gallons per Hour Kilometers per Liter - Liters per Hour. Gross Energy Consumption AHDay Enter 1T Subtract AES AHDay Enter 2A Net Energy Consumption AHDay Compute 3A Desired Days Between Charging For most boat owners this value will be one day since they will start and run their engines. In one minute the boat would travel at no slip.

Input vessel engine and transmission details and the program will calculate. 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. Pitch inches RPM max revmin 1 min reductionRatio 1215223 speed inchesmin 1 min.

The fuel consumption rate is calculated based on the data provided that depends on boat size type sailpower days of use average hours spent cruising per day. The calculator will automatically compute the 5 th variable. Maximum achievable speed estimated fuel consumption recommended propeller diameter and pitch a propeller pitch based on a required fixed diameter plus.
