I love my Gt Turbos for sailing in chop..I've got a 7.5m and I like it so much I'm going to get a 7m to use for chop sailing.
Compared to the OD it has a higher foot so it's not as good for off the wind speedsailing but it has terrific rotation , stablility , heaps of grunt and is lighter.
Many people see it rigged and are amazed at the deep profile it has and surprised when they find out it only has 2 battens.
