Now that the first piece of the deck is glued on, I made the cut-outs for the deck hatch and the portlights (the small windows on the side).
The hatch and portlights have to be mounted on a flat surface. Because the deck is curved, I had to glue on frames to compensate for the curvature. This reveals an interesting property of plywood: you would expect plywood to bend in only one direction, similar to a sheet of paper. But the deck is actually curved in two directions.
Finally, I smoothed out the transition from the deck to the frame. This was not for aesthetic reasons, but because it makes it easier to laminate the entire deck with fibreglass.
