sailboat design calculations
Sail area: in my own usage of this term, sail area refers to be the total sail area of the actual sails. in "racing" terminology, the entire area of the fore-triangle is included regardless of the size of the jib that will be used, and the main sail area is taken as the area of a triangle bounded by the mast hoist and the boom outhaul. The boat is acceptable if the result of the calculation is 2.0 or less but the lower the better. for example, a 12-meter yacht of 60,000-pound displacement and 12-foot beam will have a csf number of 1.23, so would be considered very safe from capsize.. Another important design parameter is the sail area-displacement ratio (sa/d), another nondimensional calculation that expresses the relationship between a boat’s sail area and its displacement. traditionally, it is calculated by dividing the nominal sail area in square feet by the boat’s displacement in cubic feet to the two-thirds power.. 
sailboat design calculations Delftship is yet another free boat design software for windows. this software is perfectly suitable for both professionals and students who want to design ships and boats. along with designing the boat, you can also perform basic hydrostatic and resistance calculations and adjust hull frame parameters like displacement and longitudinal center of buoyancy..
