Ultrasonic 10m to 6.5m
Just a mention I usually sail a formula board but going to Spain I could only carry one board.
I choose the Starboard Ultrasonic for its huge sail and wind range.
My 10 meter sail is a Neil Pryde RS slalom with the mastfoot at the back the board really flys.
I weigh 70 kilos and use a easy uphaul but find Im hardly ever needing it on a wide board.
With smaller sails down to 6.5M getting the set up right is critical mast foot forward and using the right fin is the key but hey Im still learning!
