Foamboat construction

Step 5 Vertical web attached

Vertical web, or keel, is glued in place, most of the glue area is provided by the foam batts. I joined pieces of plywood, very thin marine plywood in this case, using butt joints backed up by strips of the same wood. All gluing, wood-to-wood, foam-to-foam and wood to foam, was done using Titebond II, which is water-resistant, (III now available), from home centers, and which has long "open" time. The assembly process needs to be done one step at a time, with adequate time between steps to allow the glue to set fully.
