I am currently working on my first boat, a D5.
I've just finished stitching the frame to the sides and the bottom together. Construction will continue when I have bought some epoxy so hold on! I used 5.5mm and 9mm WBP plywood, I'm hoping it will stay together. I'm planning on building the spritsail version. I ended up using panel pins to fix each of the frames between the two sides after finding my brown tape to be of extraordinarily poor quality.
I am slightly worried that some of my frames have been put in a bit wonky. They are not yet fixed permanently so I plan on fixing them before I epoxy them.

I'll try to keep this thread up to date in case anyone else is interested.
