It seemed to take forever to scrape the inside of the boat clean along the planking seams! But now, finally done, I can get on with the task of fitting the inside gunnels, the floors, and the rest of the interior trim.
Even though this is a glued lapstrake plywood boat, and the gunnels are often fixed using epoxy, I am going to fasten the gunnels on using only screws. I have worked on enough boats with glued on gunnels to know how much I hate not being able to remove them! So I give the sheerstrake a sealer coat of varnish, as well as the back and under side of the interior gunnel.

Then I set about the task of developing patterns for the floors. These tie the flat sections of the boats bottom together and give the floor boards something to rest on. In a traditionally built boat, one with ribs, the ribs themselves do that task. At this point the tops are still flat all the way across, I will be shaping them finer later. While a flat floor is nice, the "V" shape of the boat at the ends would cause the floor boards to rise significantly.

Here you can see the inner gunnels clamped in place awaiting screws, as well as the floors cut out, shaped to fit the changing shape of the boat interior, and epoxied in place. Next step is to screw the gunnels in place and start fitting the riser for the seat/thwarts.
