Re: girls and heels
I'm a girl. I don't usually wear heels, nor do I like heeling!
10-15 degrees is just fine with me and the boat definitely picks up a ton of speed, 20 is okay, 30 is a lot of work and no fun at all.
I used to race and skinning my knees and getting random bruises from having the rail in the water is one of the reasons I quit. If I'm on a pleasure cruise, I'm perfectly happy to take a broader angle to the wind, go faster, and make nearly as good of time as trying to point higher while heeling an extra 10 degrees.
