The side decks are made of a plywood foam sandwich. The inside skin is 6mm plywood fixed to the deck stringers with wooden battens. These create a 20mm deep tray which will hold the Airex T92.80 foam. A 12mm plywood top layer will complete the composite sandwich. The plywood and foam are joined using epoxy resin. Once complete the sandwich construction is very strong and also provides an insulation layer.

Wow, that's an incredible number of small pieces of timber required to make the deck top framing. 3 pieces glued together for each run and each cross member! This looks incredibly time consuming!

The inner pieces of timber provide a frame to fix the bottom panel. This is a consequence of my decision to go for a foam sandwich construction. If I had opted for a simple plywood top skin it would certainly have been easier but I wanted the strength and insulation of the foam core. It's a choice. The same argument applies to the main cabin roof.
