The new Jsail V2 line where the top Opti sailors have a new sailing style where they keep the boom closer to the centerline of the boat than they used to. This way of sailing lowers the boom more and closes the leech. To counteract this we have redesigned our sails and created the 2.0 line.
Jsail has maintain the depth known from the previous models, the maximum depth only which was generally migrating towards the luff. At the same time the leech part of the sail has entertained a major lifting.
