Bubi, thanks for the link. I clicked on it and enjoyed using both YouTube windows at the same time, watching formula sailing from a head cam and from a clew mounted camera. In both videos the sailor often hung on to the uphaul while sailing. The sailor might be interested in the "I" boom Peter Ifju invented and his reasons. His discussion is on http://www.windsurfingtour.com/?p=906
I'll watch your thread for your announcement of when you have videos of the HWR and LWR.
