WebJan 15, 2024 · This picture will change with heeling, and vary with hull design. Theoretical hull speed. Theoretical hull speed is quite simply the top speed a non-planing boat can sail. The maximum speed of a boat in displacement mode is limited by the wave it creates. A planing boat is capable of climbing over its own wave. WebJul 23, 2012 · Slow Down. You probably already know that less fuel is burned when your boat speed drops by even a couple of knots.

WebJun 29, 2010 · If you have fine hulls you can use a lower Cp. Most monohulls have a Cp of 0.55- 0.57. And that is about right for displacement speeds. However the key to Catamaran design is you need a higher Cp if you want to sail fast. So a multihull should be at least 0.61 and a heavy displacement multihull a bit higher still. WebJun 18, 2024 · Many trawlers, canoes and sailboats have round bottoms. Multi-hull boat – Catamarans, trimarans, pontoon boats, and some houseboats use a multi-hull design.

WebFeb 16, 2024 · Semi-Displacement Hull. Yes, we originally indicated that there are two types of hulls, but there are three. The semi-displacement hulls are a hybrid of both displacement and planing hulls. These hulls displace water at low speeds, but they can lift when at a cruising speed. Typically, these hulls are faster than displacement hulls and more ... WebThe increased pressure from compression pushes against the stern of the hull. By pushing from the aft side, the pressure reduces the total hull resistance. It pushes the hull forward. We call this pressure recovery, and it is a vital component of efficient hull design. The stern of the vessel can be more important than the bow.
