I have a 1977 with a traveler mounted aft in the cockpit. On the traveler there are two "stops" that require me to pull up on a pin and physically slide them to move the boom for trim. There are no traveler cars and no mechanical advantage, just pure push and pull. It is scary (boom is out of control during the process), and difficult at times. Other than moving the traveler to the cabin top which is not what I want to do, is there any hardware that would improve this set up with the taveler in place?
