can be installed within the boom with a multipart tackle and cleated under the boom, not going to the mast
at all, and not back to the cockpit
. You go to the mast to adjust the outhaul.
Otherwise lead the outhaul line farther forward, close to the gooseneck and then to a block, perhaps lashed to the mast, which is free to follow the boom as it swings. This block will turn the outhaul line straight downward to the base of the mast and then back to the cockpit
. That vertical fall, along with the moveable block at the gooseneck, will reduce the change in tension on the outhaul as the boom is eased out or pulled in.
Sailing is a sport, an athletic activity, not a sedentary one.
