The webbing used for the tramp is made for car seat belts, and comes in rolls. It suffers from UV in the Georgia sun, but if you keep it covered when not in use you can get several years out of it. Its not that expensive, but is a pain to reeve through the slots and around the fiberglass rod inserts. We used sleeves bought from the same supplier to cover the spots we had to sew at the ends. The whole thing is tensioned with a stainless steel ratchet made for truckers.
Finally finished the new lifelines and rails. They now meet USCG requirements for inspected vessels. 7/64th dyneema with spliced eye thimbles and lashings for tension, instead of turnbuckles. The lashings are covered with cutoff pieces of pex tubing. After 96 total eye splices, I have the technique down for working with 7/64th cord. The trick is in getting the taper just so and covered with snag free tape so it will work back up the inside of the weave. I used a sail needle as a kind of a fid, though you can’t attach the line to it, it makes separating the strands easier. You tube has some good tutorials.
Found a soft spot in the back corner of the bridge deck. Using a hole saw, I cut out some “biscuits” from the 4mm ply on top and dug out the saturated balsa core. The blowdryer fit nicely and after a few days off and on it was bone dry. Mixed up some phenolic microballons, aerosil, chopped fibers and resin and parged it in re- using the cutouts. All is well now.
