Thor, if you think your J/30 is a handfull when it blows, you should thank your lucky start you didn''t buy the Laser.
The lasers are very light boats, and very lightly built as well. The boats are built for the Lakes (i.e. not much wind)
We raced our J/30 against a Laser frequently - below 10 knots he beat us consistently, 10-15 it was back and forth, but in anything over 15 knots he might as well stay at the dock.
I heard it said more than once (for what it is worth) that the Laser 28 was the reason Laser weren''t bulding boats any more.
