Yesterday I glued bulkheads 1 and 8 into place. Bulkhead 8 was braced from 7, and bulkhead 1 was braced using the king plank and bulkhead 2. This afternoon, I cut a groove in the king plank for the stem, then screwed it into place. It is amazing how much force was required to bend the king plank down by a measly 25-30mm to meet bulkhead 1. It is now firmly screwed together, and bulkhead 1 is not floppy anymore (it is under a fair bit of tension).
I also got the starboard seat front fitted. The basic procedure is to clamp it into place and measure how far it extends past the ends of the seat stringers. I then mark and cut notches at the forward end for the bulkhead 5 cross-braces. Then I drill and screw it into place. Finally, I can mark where to cut off the front, as well as where to cut for the cross-braces at bulkheads 6 and 8 and the notch for the bottom framing on the transom.
I was able to get a few pictures of the bulkheads as they stand (it was starting to get dark).
