60INTERVIEWBOUKE BECKER an effort to be the most innovative. But later down the line their customers will find it has gone too far and things will be reduced again. In the 90s you had the no-nose shapes; some shapers had nose widths of 25cm. Recently you had the square stubbies. There are some good things about the square stubbies but also a more tapered outline will result in a loss somewhere. Already in the second year some brands were moderating things again. So they went too far the first year. You also see brands going back from four to three fins, even if slower. With sails you see brands starting to move away from the compact wave sail designs again. Hence the yo-yo effect. But in the marketing of more extreme ‘stuff’ you can point out the good things and brush away the bad things. A brand may claim: the flat spot under the front feet helps planing and acceleration and the tail kick makes you turn. Sounds good or not? As long as you don´t mention the fact that the opposite is also the case. The flat spot works against turning and the tail kick against planing. I like to work with parabolic curves to get the smoothest flowing rocker line. Science has figured stuff like this out for us. I also like to put a bit of shape in the second batten of my sails. Some have asked if that did not move the centre of effort up. I said of course but like this you can use a smaller uk WIND SURFING sail for a given wind strength having even more benefits like weight reduction and lowering the centre of gravity plus the centre of effort. Which makes a sail actually lighter for a given wind strength, which is what you should be looking at rather than comparing weight for a sail size. Plus a bit of shape also helps to stabilize the centre of effort when powered up, thus increasing wind range.
