Correct me if I'm wrong here please, but I thought the Hobie had the right of way being the upwind boat and if the spin is up the 20 must be going downwind.

Also, let me say I have been in a situation where I was upwind with an spin boat coming down toward me when he got close he jibed but he was so close I started to tack and I was trying to stay out of the way by we got pretty close.My thought was he knew I had the right of way but was using all his speed before changing course.
