During a recent rigging survey, I was questioned about the way my boat was set up. This is a 336 that had the traveler on top of the helm. The previous owners, had done some racing (with a 336... wow) and set the boat up this way. The main sheets run up to the boom 2/3rds out toward the end. Two blocks there that run down to two more on the jib tracks. Sheets then run aft where we use the two spinaker winches for trimming them. The traveler is still attached but isnt rigged. The boom is the original (I think) Z spar that came on the boat. With only one purchase point, am I overstressing the boom? The rigger didnt say this was dangerous since I would probably run out of weather helm before snapping it off, but it is tough to find information on a boom that old. Would another couple of purchases be in order or.. should I put it back to the original configuration? I have included the pictures.Thoughts anyone?Rick
