69 in CAD files to send to the factory. When the protos got better and we had more protos, we gave them to more guys and girls to test. Even if the sails are not the lightest, girls seem to love them as well. How was it as far as prototyping went? WC can bosh out board concepts super quick but what about sails? At first we made the prototypes here on Fuerte, it takes about one week to make a sail. I had prototypes made by different factories in China to see which to choose. This takes longer depending on the time of the year. Now I have the prototypes made in China and we do the modifications here. It saves me a lot of time, so I can work on other things as we know the factory has the designs correct. Since production is outsourced and we have to adapt to the production schedule of the factory, we can’t put innovations through as fast as with the boards, which in the end doesn’t matter. Also we take our time with the boards and a shape can remain unchanged for many years. Why two different lines? What does the Karma do differently to the Slayer? Wind range and manoeuvrability. Construction-wise, the Karma has one more batten and doesn’t have a PVC or dacron luff panel to give a more stable profile. Shape-wise the centre of effort is lower, the bottom batten a bit longer, a bit more loose leach. That all adds to the wind range and ease of sailing in a straight line but reduces handling and depowering on a wave a little. The Karma is the best choice when you need more power and stability, like onshore wave sailing, sailing in currents, B&J, flat water sailing or foiling. The Slayer has a more flexible construction, a higher cut clew and a higher centre of effort to improve its handling and wave riding, so the best choice for all types of wave riding. The Slayer also has a PVC window for lasting vision through the window, essential for front side wave riding. What about adding further ranges to WC’s sail line up? Sail shape wise, we have reworked the luff curve a bit and reduced the seam shape in the foot of the bigger Slayers to reduce drag on the wave in light winds. You can always change something to make it better but you are bound to lose something somewhere else. Off course different people like different things and some have said they prefer more direct sails but most reactions we hear is that they love the smoothness. In motocross they have also moved from the lighter, direct and nervous two stroke engines to the smoother four stroke engines, even if heavier. Maybe for a skilled sailor in a contest who has just a limited time to pack a lot of action in, a direct sail is better. However, for non- contest sailing, something more reliable/predictable is better. Any additional input from others during the design process? Yes, John had a lot of input of course. Will Ward and Yannick Anton also had input along with Nestor and Jorge in Pozo. I had student engineer interns who helped putting the designs Working on a range of camberless freerace sails with the working name Elixir and a range of three kids sails called Witchy. If you were going to sum up WC’s sail line in one sentence what would that be? The most heard words in feedback is “smooth” and “power,” so I’d say: smooth reliable power? Any general thoughts on windsurfing sail? Designing sails is great fun. Thanks and praise? There are many but special praise goes to my love Peggy for supporting me in my pursuit of my dreams, John for his endless knowledge, Will and Yannick for pushing the limits of the gear on the water.
