I sail a NACRA 5.5 uni, which is boomless. It has a clewboard traveler to control position of mainsheet blocks on the mainsail, functions a little like an outhaul. Since I sail solo, adjusting this traveler involves going to the back of the boat, which is slow.

Has anyone ever rigged up a release line for this kind of clewboard traveler? What about some kind of method to pull it in?
