All of the deck framing for this boat runs fore and aft. The parts are therefore called carlins. The first carlins are short, running between the stems and bulkheads.
Once the short carlins are secure, the longer ones fit in notches in the bulkheads, a notch in the mid-frame, and end abutted to the short carlins. Through the middle section of the boat, these carlins define the edge of the decking.
Fitting them in place was a bit fussy. On the 1:1 version, there are all sorts of clamps that might be used. Not so at this scale. I ended up devising a clamp made up of a short board with notches in each side. Wedging the board between clamp and carlin did the trick.
We can see the painted watertight compartment in this picture.
