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 ...
Forward resistance comprises the types of drag that impede a sailboat's speed through water (or an ice boat's speed over the surface) include components of parasitic drag, consisting primarily of form drag, which arises because of the shape of the hull, and skin friction, which arises from the friction of the water (for boats) or air (for ice ...
This is the template test cases page for the sandbox of Template:Infobox sailboat specifications to update the examples. If there are many examples of a complicated template, later ones may break due to limits in MediaWiki; see the HTML comment "NewPP limit report" in the rendered page. You can also use Special:ExpandTemplates to examine the results of template uses. You can test how this page ...
In particular, any "displacement" or non-planing boat requires much greater power to accelerate beyond its hull speed, which is determined by the length of the waterline, and can be calculated using the formula: Vmax (in knots) = square root of LWL (in feet) x 1.34. The hull speed is the speed at which the wavelength of the bow wave stretches ...
The Cruising Club of America (CCA) put together a technical committee that analyzed race boat data. They came up with the formula to compare boats based on readily available data. The CCA characterizes the formula as "rough". A lower value is supposed to indicate a sailboat is less likely to capsize. A value of 2 is taken as a cutoff for ...

The boat has a draft of 4.00 ft (1.22 m) with the standard keel fitted. [1] The boat is normally fitted with a small outboard motor for docking and maneuvering. [1] The boat has a PHRF racing average handicap of 219 with a high of 213 and low of 228. It has a hull speed of 5.99 kn (11.09 km/h). [4]
