Anyway, pictures. First here's a close up of a clamp in place. If you look closely on the stringer side, you'll see a simple length of wood spanning the stringers:
Anyway, it's getting to the point where it looks like it might even float. Here's the stern section, with the cockpit seats all buttoned up and all the planking done. I resisted the urge to paint out the inside of the cockpit seats. I gave it a thorough coating of epoxy and left it at that.
For the join between the aft and midships section of the top plank I elected to do a scarf rather than a butt-join. This is purely cosmetic - this join isn't hidden behind seats so I don't want an ugly lump of wood showing.
