After the trial to determine paddler position, I know just where to cut the coaming hole into the deck. Trouble is, there is no deck yet. I decided to build it from cedar strips. I decided to make a deck assembly featuring a shear clamp, to facilitate final joining of deck and hull..
 

I used hot-melt glue to temporarily attach the shear clamps to the side panels. They were then planed to match the shear joint angle.

Forms were attached temporarily with hot glue. Here are a couple in the aft deck.

Gluing the shear strips turned out to be a monumental task. The strip is flat in the ends of the boat, but cambered up at the cockpit. I finally gained control by filleting the shear strip to the shear clamp with a mixture of epoxy, silica, and wood flour.

The second shear strip is glued.

After the difficulty of installing the shear strips, the rest were relatively easy.

Here's a trick: If a strip does not end on a form, that end may sink below flush while gluing. I used a few "mini-forms" glued to the underside of the deck to solve this problem. Here, a scrap strip has hot glue applied...

...and the wire guides it in place as the hot glue hardens. I will knock off  this piece when the deck is separated.

Never sell tools; yer kids may need them! Background: the aft deck. Left to right: My fancy Stanley low-angle block plane, The last deck strip(!), my father's jackknife, my grandfather's block plane, my great-grandfather's C-clamp. Top, my great-grandfather's plane. All scary-sharp and ready to go. All used in stripping the deck.

The deck, completely stripped.
