1 dzień temu · Calculation Formula. The core of the Boat Speed Calculator lies in Crouch's formula: \[ S = \sqrt{\frac{P}{D}} \times C \] where: \(S\) represents the boat's top speed in miles per hour, \(P\) is the power supplied to the boat in horsepower, \(D\) is the displacement of the boat in pounds, \(C\) is the Crouch constant, specific to the boat's type.
15 cze 2024 · For a boat, the formula S = √(P / D) × C can be used to determine the speed, where: S is the speed of the boat. P is the power applied to propel the boat. D is the drag acting against the boat. C is a constant, which in this context is often referred to as the Crouch constant.

25 cze 2024 · Sail Area to Displacement Ratio. INSTRUCTIONS. Sail Area-Displacement Ratio (SA/D): Sailing and Navigation Calculators. Compute the Distance Between two Points on a Sphere (Great Circle Arc) using degrees, minutes and seconds verses decimal degrees.
6 dni temu · The formula to calculate the Ballast Displacement Ratio is: \ [ BDR = \frac {B} {D} \] where: \ ( BDR \) is the Ballast Displacement Ratio (lbs/lbs), \ ( B \) is the total ballast (lbs), \ ( D \) is the total displacement (lbs). Example Calculation.
27 cze 2024 · The basic formula to calculate displacement is a reworking of the velocity formula: d = vt. Where d is displacement, v is average velocity, and t is the time period, or the time it took to get from point A to B. If the object has constant velocity, solving for displacement is straightforward.
5 dni temu · VMG Formula. The formula to calculate VMG is as follows: \ [ VMG = BS \times \cos (TWA) \] Where: \ (VMG\) is the Velocity Made Good in knots, \ (BS\) is the boat speed in knots, \ (TWA\) is the true wind angle in degrees. How to Calculate VMG. Determine the boat speed in knots.
