I am trying to set up the outhaul system on my O25. There is a pully on the end of the boom and two pullies along the starboard side, but no cleats. The line attached to the cringle runs through the pully at the end of the boom and forward to one of the two pullies on the boom, but there is no way to tie it off so that I can quickly release it for adjustment. Does anyone have a recommendation of brand, size, etc. Thanks for your thoughts.
