True enough! As I recall, keeping 90 degrees apparent wind was an essential part of the bargain. Guess I should have mentioned that small detail earlier. <img src="http://www.catsailor.com/forums/images/graemlins/blush.gif" alt="" />
Ah, OK <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
I definitely think it pays to go a bit hotter than 90 degrees apparent wind. I tend to go for about 70.
I was quite surprised to discover that it pays even in very light wind. At one of the races at Grafham the wind dropped right off and I was resisting the temptation to go high. When I realised the F18s were getting past me, I started sailing the same angles as them. The angles felt really high, but I was now beating them downwind.
