Model sailboat keel design
Modern sailboat design: ballast stability - wave train, A keel capable canting 55 degrees requires 25 60 percent ballast fixed keel support hull sail plan. result lighter boat higher sa/ ratio / ratio. modern raceboat ballast keel canted windward.. Modern sailboat design howstuffworks, Modern sailboat design evolved create wider, sleeker, structure. width increases stability, basic components refined improve sailing efficiency. keels longer leaner, allowing closer, quicker tack. larger surface area displaces water tighter tack.. Keel design keel analysis, Stallion 3d. multisurface aerodynamics packages speed production keels, rudders sails combining design testing single easy-- software package.. software improve airfoil sections, optimize planform shapes size aerodynamic surfaces. designs tested minutes compared existing appendages..
