1. Improve acceleration after start and gybing without sacrificing stability or speed. Essential when you are coming out of a gybe or drag racing to the next mark where you want to make use of the smallest gust to move past your opponent.
2. Try to further reduce the weight, especially of the bigger sizes. Essential to make the sail less physical to sail and easier to pump.
1. Kai has improved acceleration by adding more depth to the sail, most noticeably in the boom area. In the upper part of the sail (batten #1 to #4) Kai has replaced the cross seams with a full luff panel which enables him to control the added profile. The result of these modifications is extra dragster-like acceleration. Kai also reduced the aspect ratio (especially on the larger sizes) which results in a slightly wider and shorter sail. This longer chord also has a very positive effect on the acceleration.
2. After the success from last year where Kai had reduced the number of battens from 8 to 7 on all sizes up to 8.0, he now goes one step further. Now even the big sizes have only 7 battens. This makes the sail more dynamic and noticeably lighter in the hands. Kai was able to maintain the stability through stiffer battens and improvements in shaping. In addition Kai has replaced the top 3 batten tensioners with our superlight Mini.Rocket tensioner, one of the lightest tensioners on the market. All these weight reductions in the top of the sail have a very large impact as it effects the swing weight of the sail. As a result especially the bigger sizes are remarkably lighter, making them less physical to sail and easier to pump.
