Hull speed or displacement speed is the speed at which the wavelength of a vessel's bow wave is equal to the waterline length of the vessel. As boat speed increases from rest, the wavelength of the bow wave increases, and usually its crest-to-trough dimension (height) increases as well. When hull speed is exceeded, a vessel in displacement mode ...
The boat has a draft of 5.00 ft (1.52 m) with the standard keel. [ 1 ] [ 2 ] Early production versions had a Palmer 22 hp (16 kW) inboard engine , while later ones came with a 30 hp (22 kW) Universal Atomic 4 gasoline engine and finally an Atomic two cylinder diesel engine , for docking and maneuvering.
Sailing hydrofoils achieve boat speeds up to twice the speed of the wind, as did the AC72 catamarans used for the 2013 America's Cup. [20] Ice boats can sail up to five times the speed of the wind. [21] [22] Lateral force is a reaction supplied by the underwater shape of a sailboat, the blades of an ice boat and the wheels of a land sailing craft.
The flat-bottomed hull design allows sustained wave surfing and commensurate high speeds. [5] A raised-deck version was also designed, but, despite orders, only one was built and later orders were cancelled. [1] [2] The boat has a draft of 5.58 ft (1.70 m) with the standard keel. [1] [2]
The boat has a draft of 7.25 ft (2.21 m) with the standard keel. ... The design has a hull speed of 7.88 kn (14.59 km/h). [2] See also. List of sailing boat types ...
The Hunter 30T is an American sailboat that was first built in 1991. [1] [2]The Hunter 30T is a development of the 1988 Hunter 30-2 design. [1] [2]The design was originally marketed by the manufacturer as the Hunter 30, but is now usually referred to as the Hunter 30T to differentiate it from the unrelated 1973 Hunter 30 design and the 30-2, which was also marketed as the Hunter 30.
The hull length is 28.08 ft (8.56 m), but including the bowsprit and boomkin it is 37.75 ft (11.51 m) [1] The boat has a draft of 4.83 ft (1.47 m) with the standard keel. [1] The boat is fitted with a Swedish Volvo MD 7A diesel engine of 13 hp (10 kW) or a Japanese Yanmar diesel of 27 hp (20 kW) for docking and maneuvering. The fuel tank holds ...
The boat is fitted with a Westerbeke diesel engine of 27 hp (20 kW). The fuel tank holds 30 U.S. gallons (110 L; 25 imp gal) and the fresh water tank has a capacity of 86 U.S. gallons (330 L; 72 imp gal). [1] The design has a PHRF racing average handicap of 180 with a high of 192 and low of 156. It has a hull speed of 7.18 kn (13.30 km/h). [6]
