2 dni temu · Displacement tonnage measures the total volume of water a vessel displaces, equivalent to its overall weight. Deadweight tonnage measures the ship's carrying capacity, including cargo, fuel, passengers, and crew, but excluding the weight of the ship itself.
4 dni temu · So a boat with a 600 US gal. fuel tank plus a 200 US gal. drinking water tank adds more than 6700 lbs in pounds to the weight of the boat with full tanks. It’s difficult to verify other weights, such as a hardtop on a 60-foot yacht, the presence or absence of a crane or hydraulic system, the addition of teak everywhere…
5 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 · 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 · To determine your boat’s average speed, all you need to know is the horsepower, boat weight (displacement), and Crouch’s constant. Crouch’s constant depends on the type of boat, but for most recreational vessels, it’s 150. You can travel 30 to 50 miles per hour on an average bass boat or drift at about 20 mph on a trawler.

3 dni temu · Ships float in the water at a level where mass of the displaced water equals the mass of the vessel, so that the downwards force of gravity equals the upward force of buoyancy. As a vessel is lowered into the water its weight remains constant but the corresponding weight of water displaced by its hull increases.
