sailboat design basics
Performance. generally light displacement brings performance benefits due to the higher power to weight ratio and reduced hull drag through having a smaller wetted area.. this is borne out by two important design ratios, the displacement/length ratio and the sail area/displacement ratio. length too has an impact on performance, as can be shown by another sailboat design ratio, the speed/length. Boatbuilding basics "the first thing that has to be defined is how the yacht will be used," says donald l. blount and assoc.'s designer chris swanhart. "a fishing yacht, a cruiser or a fast offshore racing boat all have different design requirements." for starters, a sportfish yacht has unique features that set it apart from other types of vessels.. Modern sailboat design has evolved overall to create a wider, yet sleeker, structure. while the width increases stability, other basic components have been refined to improve sailing efficiency. keels are often longer and leaner, allowing for a closer, quicker tack. their larger surface area displaces more water for a tighter tack.. 
sailboat design basics Building boat hulls is not a big headache but these basic points have to be kept in mind if you want a perfect streamlined hull. say you are designing a ballasted boat; make sure that the weight of the boat (the up-weight) is always forty to fifty percent greater than the weight of the ballast..

(it assumes each processing recipe will yield an average of 2.5).
