Air Cases

The long job of removing the Air cases(floatation tanks) these are made of timber (redwood) and then covered with canvas and painted to make them watertight.

These filled the hold, & all empty voids so the boat became "unsinkable", these were in the original build, not just added when she was made self righting.
