Jeff, I stand corrected on the sails. What is the Aspect Ratio number? I thought it would be a rather "Low" number for the speeds she was attaining. Ole Thom I haven't found the specs for the boat, but the line drawings show the aspect ration to be over 3 to 1. Plus, with the square top, the effective ratio is much higher. Think of it as simply removing the top quarter of a sail - the part that generates little lift but contributes heeling moment. Add to that the fact that the sails are actually wing sails, with two layers of cloth over a rotating mast, and internal battens adjusting curvature ... I'm sure they have just the lift to drag ratio the designers want for the boat. Its hard to argue with 45 knots. |
