1 dzień temu · Yes, by rearranging Crouch's formula, you can estimate the necessary horsepower to achieve a specific speed, provided you know the boat's displacement and the appropriate Crouch constant. This calculator simplifies the complex calculations behind boat speed prediction, making it accessible and useful for a wide range of users, from boat ...
3 dni temu · This useful calculator computes an estimate of boat speed for a modern planing monohull using inputs of the power at the propeller shaft, the total boat weight, and a coefficient called the hull factor.
3 dni temu · Water Displacement Formula. The formula for calculating the density of an object using water displacement is given by: \[ D = \frac{m}{FW - IW} \] where: \(D\) is the density in grams per cubic centimeter (g/cm³), \(m\) is the mass of the object in grams, \(FW\) is the final water level in milliliters (mL), \(IW\) is the initial water level in ...
2 dni temu · To calculate the pontoon weight or the weight it can support, the formula is: \[ PW = PV \times 62.43 \] where \(PW\) is the Pontoon Weight in pounds (lbs), \(PV\) is the total volume of the pontoon in cubic feet (\(ft^3\)), and 62.43 is the weight of freshwater in pounds per cubic foot.
4 dni temu · Hydrofoils start generating lift as soon as your boat is moving through the water. However, the amount of lift increases with speed, making it more noticeable at higher speeds. The exact speed at which a hydrofoil provides optimal lift depends on factors like boat type, size, and hydrofoil design.
3 dni temu · Simplified Formula. Fluid Pressure - P. (PSI) = Force (Pounds) / Area ( Sq. In.) P = F / A. Fluid Flow Rate - Q. GPM= Flow (Gallons) / Unit Time (Minutes) Q = V / T. Fluid Power in Horsepower - HP. Horsepower = Pressure (PSIG) × Flow (GPM)/ 1714.
4 dni temu · Port approach. If a powered vessel approaches you from the port (left) side, you are the stand-on craft. This means you have right-of-way, so you can continue in the same direction at the same speed. Stay alert and be ready to adjust as needed. If you are approaching another vessel from the port (left) side, you are the give-way craft.
