Webb26 mars 2010 · As a very general rule the maximum speed of any displacement hull--commonly called its hull speed--is governed by a simple formula: hull speed in knots … Webb8 dec. 2024 · S = Speed = √ (P / D) * C where S is the boat speed and C is the Crouch constant. The above equation is known as Crouch's formula. Note: The formulation and value for the Crouch constant are specific for units such as the speed is in miles per hour and displacement is in pounds.
Webb15 jan. 2024 · Theoretical hull speed is quite simply the top speed a non-planing boat can sail. ... In short: Longer waterline means longer wave. Longer wave means higher speed. The formula, as mentioned earlier, is 2.43 multiplied by the square root of the waterline length (in metres). Webb20 juli 2011 · Anyone who has ridden in a RIB planing at speed will have experienced how they are finely balanced with minimal grip on the water! Hull speed can be calculated by the following formula: v=1.34 × √LWL where: "LWL" is the length of the waterline in feet, and "v" is the speed of the vessel in knots
