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 ...
A velocity prediction program (VPP) is a computer program which solves for the performance of a sailing yacht in various wind conditions by balancing hull and sail forces. VPPs are used by yacht designers, boat builders, model testers, sailors, sailmakers, also America's Cup teams, to predict the performance of a sailboat before it has been built or prior to major modifications.
The boat has a draft of 7.42 ft (2.26 m) with the standard keel fitted. The boat is fitted with a Universal M-25 diesel engine of 30 hp (22 kW). The fuel tank holds 40 U.S. gallons (150 L; 33 imp gal) and the fresh water tank has a capacity of 40 U.S. gallons (150 L; 33 imp gal). The boat has hull speed of 7.44 kn (13.78 km/h).
The boat is fitted with a Japanese Yanmar 4JHTE diesel engine of 76 hp (57 kW). The fuel tank holds 84 U.S. gallons (320 L; 70 imp gal) and the fresh water tank has a capacity of 214 U.S. gallons (810 L; 178 imp gal). [1] [4] The boat has a hull speed of 8.68 kn (16.08 km/h). [2] [4]

The boat has a draft of 3.50 ft (1.07 m) with the standard keel and is normally fitted with a small outboard motor for docking and maneuvering. [ 1 ] [ 3 ] The design has a hull speed of 5.8 kn (10.7 km/h).
Working with German boat yard Abeking & Rasmussen, he designed a prototype which he showed to yacht clubs along the east coast. The initial cost of the boat was $1800, below that of competing boats. [8]: 14 The Atlantic is a racing keelboat, with early examples built predominantly of wood and later ones from fiberglass, with wood trim.
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.
