This continued report presents a numerical method based upon the Vortex Panel Method for analyzing aero-dynamic characteristics of 2-dimensional double membrane sails, and it proposes an approximate method for estimating aero-dynamic characteristics of a three dimensional triangle double membrane sail by using the numerical method. A series of numerical calculations are executed for any more combinations consisted with a double membrane sail, a single membrane sail and a wing section by using the present numerical method. And, numerical examples are shown about a triangle double membrane main sail, calculated by the approximate method. It is confirmed that the sloop rigged with double membrane jib and double membrane main sail is much superior to the other combination rigs, and that the approximate method is useful for rough estimations of aero-dynamic characteristics of a three dimensional sail.
