I raced against that boat in Vancouver in 87'. It was almost as fast as an Aussie 18 footer around the course.
The boat never went over, so I can't tell you if it will
hold up. It is the fastest upwind boat I have ever seen.
I believe that you might want to set a limit of about 18 knots true for sailing on it until you've sailed it a bunch.
If your not too experienced, make that 10 knots true. The wing is very, very powerfull.
