Yesterday I snuck back to the boat shed with my little apprentice.
We found that the epoxy had set nicely. So far I’ve yet to have had a problem with the West system epoxy even when skirting the edges on the temperature limits of the 205 fast hardener. But it is always a nice relief to find the laminated Wood solidly bonded.
So we started the process of removing the multitude of clamps holding the laminated frame for 24 hours. I then put it in the hull at the appropriate location.
The epoxy squeeze out still needs to be cleaned up and the whole frame will be planed down to 1″ thick. The outer frame will be bevelled to match the angle of the hull and the ends will be cut down to mate with the completed inwhales.
I also flipped the frame upside down and found that it looked like a great shape to mimic for an eventual canvas cover for camping… But that is a project for much later. First I need to finish the inwhale laminations and continue to fit out the interior of the boat.
Two weeks ago on a regular Wednesday night I was crewing on a good friend’s sailboat. We had a great race in very shifty winds and crossed the finish line in second place in our division. Only to realize that a change in the course we thought had only applied to div1 and div2 also applied to us. We had rounded the wrong windward mark on the third rounding. Having figured it out before the race committee did, and to avoid any later protests in good sportsmanship we informed the race committee that we would retire and forfit the race. Another boat close to us who had sailed the same course as us was adamant that they had sailed the right course and was going to protest the race committee.
Having retired our thoughts were already turned to putting the boat to bed and pulling the beers out of the ice box once we were tied to the dock. So I still don’t know what happend with the protest.
What happened after that is that one crew member noticed two small cracks in the gel coat of the central bulkhead of the boat on the port side where the chainplate is bolted. We had a lively conversation about what it meant and how extensive the repairs might have to be. The following Wednesday the crew came back to help prepare the boat for repair. Remove as much stuff as possible from the boat and detach the shrouds from the port chainplate and then remove the chainplate bolts.
The next Wednesday we started to explore and cut into the forward side of the bulkhead to see what had caused the port chainplate to move up and crack the bulkhead Fiberglass.
What we found is that the location where the chainplate goes through the deck has historically not always been well sealed. Water had come through and seeped into the bulkhead which is a sandwich of Fiberglass and balsa wood core. The sandwich of balsa was saturated and the wood was rotten and soft which compromises the strength of the bulkhead.
So what next? Clean out the rotten balsa replace it and re-glass? Or replace the bulkhead entirely?
That is the question we are asking ourselves.
