The D-Spar is supplied equipment; what can you do to it?
The rules say the sail has to be attached on both sides. Basically the top 13 feet are the part that we can control as we wish. The bottom 6 feet or so we can control as we wish as well. Between those zones is the challenging part. A lot of it is about the batten-setup orientation, which is open in this midzone. We can change battens a lot to try different positions and tapers, which all makes a big difference. Again, the shape we want on the windward side might not be what we want on the leeward side.
Are there restrictions on batten materials?
They can’t be inflatable. They have to be able to laid flat, but can be tapered; however, there is plenty you can do there. There’s a lot of money for batten manufacturers to make this time around. – Full story
