Progress is being made. The amas have been shaped and sanded, and they are ready for their skin to be applied.
The main hull has also been generally defined. It will be 21 feet long, 10 inches wide at its widest, and 6 inches thick in from the front of the cockpit to the just behind the seat. The bottom of the bow is 4 inches above the lowest part of the boat, and the stern will be 3 inches above the lowest part of the boat. There will be extra volume starting at the bow and ending before the cockpit to help keep the bow from burying itself in the waves when surfing.

The skeleton of the boat is Foamular 250 "pink" foam insulation I picked up from Home Depot. There are two different thicknesses being used. Two inch thick foam is being used for the bottom and for the interior bulkheads in the cockpit area. It is also being used for the joining the three sections of the hull. One in thick foam is being used for the sides and top of the hull, as well as the fore and aft hull bulkheads.

The hot wire cutter was doing a lot of cutting today!
As an aside, it looks like I bought at least two extra panels of the 1 inch insulation. It doesn't look like more than one sheet will be needed for the added volume for the bow above deck.
Once the hull is glued together (using Gorilla Glue), the edges and the hull bottom will be shaped with a hand block sander.
My order for fiberglass, resin and pigment also arrived today. I had hoped to get 40 inch wide 5.6 oz S2 glass, but Fiberglass Supply was out of stock. They suggested substituting 30 inch wide 5.6 oz S2 glass, and I agreed. I'll just have to wrap the hull a little differently than I originally planned, which will put overlaps about every 27 - 30 inches down the length of the hull. Those overlaps will act like ribs and help stiffen the boat even more.
