Well todays accomplishment was the start of replenishing the supply cabinet with items needed for fiberglass boats.
41.00 for glass supplies and bondo.
The S-boat was designed around the concept of the hull being split (top and bottom) along the water line.
A fore and aft dry compartment with an area for a ballast tank in the middle. By the time I had built the second boat I realized the tops of the ballast tank and dry compartments should be at the water line. Any airspace in the ballast tank above the surfaced waterline is wasted adding no boancy. The same goes with the material in the dry boxes. It is wasted weight if they are above the waterline.
I used the hull as part of the dry compartment by simply putting in bulkheads fore and aft and adding a fiberglass top to each compartment (at the waterline) of flat fiberglass panels (Made the panels by laying them up on glass sheet ot give a smooth surfase for hatches to RTV to.
Thought I would post these shots of the original Navy model of the S-48. It is in the Washington Navy Yard Museum
Ill work up some drawings as I go and post them.
