Thanks, Joe,
Glad to show you the boat. Could use your input. See your 'private message.'
Was wondering if the rigid vang performs some of the functions of the standard travelor in the cockpit making it possible to go back to the original 3-block mainsheet. I'm not predjudiced against any right-on solution. It's not hard to 'see' it in stainless steel tube.
Mike's Contessa link above has another guy's installation using tube - tho not as impressive as the angles and wood one it looks lighter and the idea could be borrowed to get the blocks and/or travelor off the deck and out of the cockpit. If the lead to the boom was OK. ????
