Sounds like fun, I always like a high, hot spinnaker reach, that's why I got a spin cat!

BTW, I got an A in high school Geometry, wihtout even studying much. What you have drawn in no way resembles a true trapezoid...that's why I was wondering what the real intent was, of the 'reach mark' and where the marks would be placed, ie spin up or down on the reach.

Oh, and why not number them so you turn them in sequence, from 1 to 2 to 3 to 4, instead of 1 to 4 to 2 to 3?

Miss Camp (my HS Geometry teacher) would be pissed!
