I don't see them on many boats, but I would like to add one. I sail distance races at our local club, and this time of year the wind is very light, and the downwind legs are long, choppy and slow. My boom likes to ride up and it feels like I lose some power when sailing my downwind course to the next mark.
In the Bob Curry article, it appears that he has the hooks from one of those rubber tie downs, with a shock cord doubled around the end of the hooks and taped. It also appears that he has added a small loop to his gooseneck to hook the front of the vang.
Is that all there is to it?
Where exactly does it hook in to the front of the boat?
I'm not expecting a huge boost in performance, just experimenting more than anything.
