Point- 7 sails. I ordered some AC-1 sails together with C-100+ masts. I first came in contact with Point-7 when I went to Lake Garda in 2008. Then I saw the new sails on Boot 2010 and I was convinced.
Point-7 stands for 0.7 which is the highest score you can get in a windsurfing competition. The sails are originated from Italy and the company was started by Andrea Cucchi. They now also have a testcenter on Fuerteventura were the sails are designed by Peter Munzlinger.
