1 dzień temu · The Boat Speed Calculator, powered by Crouch's formula, is a tool designed for enthusiasts and professionals in marine design and navigation. It assesses the potential top speed of boats of various types by considering their power, displacement, and a unique factor known as the Crouch constant.
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.
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).
5 dni temu · The Displacement to Length Ratio (DLR) is a crucial measure in naval architecture, indicating how heavy a boat is relative to its waterline length. This ratio is used to estimate the boat's performance, including its speed, stability, and sea-keeping abilities.
25 cze 2024 · The Capsize Screening Formula calculator computes a metric to describe a boat's stability in rough seas. A CSF less than 2 indicated a boat with better offshore stability. INSTRUCTIONS: Choose units and enter the following: (D) Boat Displacement (B) Length of Beam; Capsize Stability Formula (CSF): The calculator returns the ratio as a real numbers.
22 cze 2024 · Simple formula to calculate the Boat Speed using often the Froude Number or the Relative Speed coefficient, see graphic as well. Used formula for speed: Vb : Vr x √LWL in m/s. Typical example of a Class M with LWL of 1.27m : √1.27 = 1.126. therefore : 1.25 x 1.126 = 1.408 m/s = 5.071 km/h.
