..., although a small amount of sheet easing is beneficial. The lift distributions for all sail trim combinations investigated are underloaded near the masthead relative to an elliptic distribution, which means that any additional twist in the main increases the induced drag. The difference in performance...

The same thing can be said of sail trim parameters like traveler angle and twist. Four force degrees of freedom allows us to use The word...

... In velocity prediction programs for yachts the problem of modelling sail forces is greatly complicated by the fact that the sail shapes are not fixed. For a given sail plan, alterations in sail trim produce a wide range of combinations of lift, drag and heeling moment. While the original...
