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.
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.
1 dzień temu · To calculate your boat’s average speed, you need to know the horsepower, displacement, and Crouch’s constant. Crouch’s constant depends on the type of boat. Most recreational boats have a Crouch constant of 150. Higher speed boats have a Crouch constant of 190 and racing boats 230. For displacement, use your boat’s weight.
1 dzień temu · The coefficient proposed allows to relate the flow rate of the air injected with the velocity condition of the boat. It is very important in order to take into account the effects of the speeds of the boat on the drag reduction of the system. ... with speed. Drag decreases as air pressure increases, stabilizing once optimal pressure is reached ...
5 dni temu · This article investigates the vibration analysis of the mast on the bridge top of a 28 m tugboat, in the quasi-static regime. The study aims to determine the natural frequencies using an equivalent dynamic model of the mast and considers the accelerations of different degrees of freedom of the vessel. Practical design and reinforcement strategies for the local bridge top structure are proposed ...
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.
