Boat building is the design and construction of boats (instead of the larger ships) — and their on-board systems. This includes at minimum the construction of a hull , with any necessary propulsion, mechanical, navigation, safety and other service systems as the craft requires.
A wave-piercing boat hull has a very fine bow, with reduced buoyancy in the forward portions. When a wave is encountered, the lack of buoyancy means the hull pierces through the water rather than riding over the top, resulting in a smoother ride than traditional designs, and in diminished mechanical stress on the vessel.
After Campbell's achievement of the 300 mph land speed record with Blue Bird in 1935 he retired from advancing the land speed record. Shortly afterwards he switched his attentions to the water speed record, at that time dominated by the American Gar Wood. [1] Blue bird was designed by Fred Cooper and built by Fred Goatley of Saunders-Roe.
The Sea Sled is a direct forerunner of the modern high speed catamaran or tunnel hull. The reduced friction is due to a "trapped" gas film between the hull surface and water. A similar effect is seen in super-cavitating torpedoes where a gas generator creates a film separation to water friction.
No-Vac at speed, 1933 Miss Jarvis on transport trailer, 2010 Hydroplane Miss America II on the Maumee River in Toledo, 1920. A hydroplane (or hydro, or thunderboat) is a fast motorboat, where the hull shape is such that at speed, the weight of the boat is supported by planing forces, rather than simple buoyancy.
The Sailfish sailboat is a small, hollow body, board-boat style sailing dinghy. The design is a shallow draft , sit-upon hull carrying a lateen rigged sail mounted to an un- stayed mast . This style sailboat is sometimes referred to as a "wet boat" because, with its minimal freeboard , the sailor often gets splashed by spray as the boat moves ...

The boat has a draft of 18 in (46 cm) with the daggerboard extended and 6 in (15 cm) with it retracted, allowing operation in shallow water or beaching. It can also be transported on a trailer or automobile roof. [1] [2] The design has a hull speed of 3.8 kn (7.0 km/h). [9]
