I got about 2 hours in yesterday and about 3 hours today and have managed to get about half the hull panels filled. I am able to do them much faster and much neater than I did on the first hull. I think I will have the whole hull filled by the weekend and will start working on sanding the joins smooth and round in preparation for glassing.
I have also filled the gap at bulkhead 3. With the plug cut, it was just a touch too tight so I trimmed it with the rasp and it went into place easily, so I just covered both edges with glue and put it in place and cleaned up the excess glue into neat coves. I was just a little short with the plug so I filled the bottom 10cm with filler. In all I reckon this took me about 40 minutes to fix. And as far as structure, it will make no difference as this is just a core repair and the whole join will be covered with glass on both sides.
I still have the join in the keel to fill and I will attempt that next week once my knee is a little stronger as I will have to spend a lot of time on the top rung of the ladder. I am planning on the weekend after next to glass and bog the hull, Saturday to glass, Sunday to bog.
