The deep V form (between 18 and 23 degrees) is only suited to high-powered planing boats. They require more powerful engines to lift the boat onto the plane but give a faster, smoother ride in waves. Displacement chined hulls have more wetted surface area, hence more drag, than an equivalent round-hull form, for any given displacement.
A padded V-hull is a hull shape found on both pure race boats and standard recreational craft. A variation of the more common V-hull , which has a V-section throughout the length of the vessel, a padded V-hull has a V-section at the bows and the forward part of the keel which then segues into a flat area typically 0.15 metres (5.9 in) to 0.25 ...
A V-hull, is the shape of a boat or ship in which the contours of the hull come in a straight line to the keel. [1] V-hull designs are usually used in smaller boats and are useful in providing space for ballast inside the boat.

US Navy SWCCs train with a modified go-fast boat during a training exercise in Mississippi. A typical go-fast is laid-up using a combination of fibreglass, kevlar and carbon fibre, using a deep "V" style offshore racing hull ranging from 6.1 to 15.2 metres (20 to 50 ft) long, narrow in beam, and equipped with two or more powerful engines, often totalling more than 750 kilowatts (1,000 hp).
The combination of symbol and hull number identify a modern Navy ship uniquely. A heavily modified or repurposed ship may receive a new symbol, and either retain the hull number or receive a new one. Also, the system of symbols has changed a number of times since it was introduced in 1907, so ships' symbols sometimes change without anything ...
From a design point of view, a boat’s hull type reflects its use and the waters it will be used it. These include displacement hulls, vee-bottom hulls, modified vee-bottom hulls, deep-vee hulls and trim tabs for vee-bottom hulls. The three main hull materials are wood, reinforced fiberglass and metal. Wood hulls may be made of planks or plywood.
