On the DVD of all 5 videos, Tim was a bit delayed with a project on his real job. He working on it now.

The Upwind and Roll Tacking video goes much more in depth on how to tack fast.

And YES, backwinding does stop the boat. Racing sailors don't want the boat to stop.., thus the reason we developed this roll-tacking procedure that truely works. The Prindle Manual was probably written before the development of the cat roll tack.

And yes it works great for uni-rigs.
