So OK ... sort of working on a guide for spin work.

1. windex at 7 ... gibe to 5 -- 60 degrees.
for example we were headed 330 and gibed to 30.
Basically this is our broad reach gibe figure ... any you guys have similar?

2. Windex at 9 ... gibe to 3 -- 160 degrees.
this was a little bit of a suprise as we thought we would do 180.
[this was a question we were trying to resolve for a race to a nav mark that we came into on beam reach and were wondering if we could hold the spin on 180 return ... which we couldn't]

will have to repeat both of these tests with different cut spins.

What angles do you guys like to use under spin for best VMG to mark?
