Here is the first pontoon, right side up, with the bulkheads in

place. They will be set permanently in place by fillet (fill-it) and fiberglass tape after the two coats of resin dry.
Interior view of second pontoon with out the bulkheads in

place. As you can see, the bulkheads play a vital role increasing the volume of displacement for when the whole build hits the water, in addition they also provide extra strength to the pontoon itself, enabling a few sheets of 1/4" plywood to support almost half a ton of weight!
That's all for now. Current plans are to get this in the water by this Sunday, but I'll have more build pictures posted soon and please feel free to post any questions you may have.
