Repaired with 16 1/8 rivets on a patch from an old crossbar. We used West Epoxy and filler underneath. The patch came form a H16 wrecked by the local Tsunami Brothers--one of many cats they've wrecked! One day I rescued their 'crew' (the wife) after she'd been hit on the head by the improvised boom--a piece of 2x4--and knocked overboard. The second time I plucked her outta the sea after she'd dislocated her shoulder. I believe she now lives in the outback!
Old holes in the crossbars--some unused and some worn out of shape from excess movement. After adding epoxy all 24 rivets had to be re-drilled from the castings and the cleat holes too.
Replacing the Trampoline
Having small hands I dread replacing the tramp but this time I got it right; nice and tight and only Crazy Minnie to help--or get in the way.
Using some tips I found on this forum here's what I did:
I used the mainsheet to pull in the sidebars. Don the sailing gloves. Lace the tramp at the center. Lace the rear section and used an old spade handle (after I broke the handle of the rubber mallet) to lever and tension the line against the rear beam, always pulling UP through the grommet and planting a piece of doweling in the grommet to prevent the line retracting while tensioning the next. I went over these two rear lines several time and then went back to the center again using the T-shape of the handle to lever and tension without damaging the tramp. In the past I used vice grips as recommended by some users but found it damaged the line. The wooden plugs are a great idea.
Hull/Deck Seam Repairs
Starboard Hull (outside) split from the side-stay bolt forward to the bow.
A clean separation (luckily) with no broken or torn fiberglass.
Work done by my friend Stuart using West System Epoxy and filler
thickened to a peanut butter consistency as advised by MBounds (Hobie forum).
Remove the old epoxy with a disk grinder.
Use small clamps --lightweight are better than heavy so as not to upset the epoxy or squeeze it too tight.
Check your own boat--you may be surprised to find cracking in the seams!
