Luff Track removal and installation instructions
Hobie Cat USA
In regards to trailering, we leave all the wires, trap included, (like Chris said undo the bungees under the tramp) attached to the mast tang. When the mast is down, pull the step pin and walk the mast forward, set the mast on the trailer support, tie off the forestay around the base of the mast using the jib halyard and any cleat. Pull all the shrouds and trapeze wires up towards the front (towards the base) until the shrouds are taught and lash right to the mast with a few short bungees or rope. Coil up the excess trap wires and tie to the hiking straps on the tramp. Secure the mast to the trailer support and at the rear crossbar with your throwable cushion underneath it for protection. Put your sails, boom, block/sheet and hiking stick in the sail bag and tie caddy corner across the tramp, and per rk04 attach the jib clew to the bridle/forestay chain plate and tighten your jib sheet. Tie the jib sheet tail to the hiking strap.
Cool thing is you don't really need a lot of extra stuff to "sustain life" with a 16, but things like a sail tube and box on the trailer are nice.
