November 28, 2003 - Hull Structure: Engine Stringers
This is the final update before the deck is placed on the boat. Hence, this section features a detailed look at the hull as of November 28, 2003. Because of the level of detail, this update has been organized by general categories, and sub-divided by specific categories.
As noted in an earlier update, the engine stringers are original! The original aluminum skins were removed as they were heavily corroded. This corrosion had "squeezed" the oak core, and required that some portions of the stringers be brought up to thickness. This was accomplished with spruce plywood.
One major design change to strengthen the boat took place with the stringers. In the original design, the frames were mounted on the stingers, and aluminum pieces were added between the frames. This compromises the majority of the aluminum's strength. Thus, in the restoration, we skinned the stringers with one piece of aluminum running from the transom up past the engine compartment. This will significantly increase the strength of the boat.
One detail not easily visible in these pictures deals with the stringers through the engine compartment. Here, the top of the stringers have been angled downward toward the middle of the boat, as well as recessed. This is to accommodate the flash pans that will be added much later to prevent engine exhaust from burning the wood in the boat.
