12kts is nothing. The dinghys were all designed to sail well in 10-12kts. The Laser was designed for under 10kt Canadian lake sailing. That is why it is overpowered at 17kts. It's not about working well in your boat. I'm concerned about you ripping the deck/mast step off. I had it happen to one of my old Laser's.Why? Seems to work well on both of mine. All I have to do is correct settings to reduce weather helm.
