I've looked around but cannot find anything. Does anyone know what the structure under the cabin liner is, particularly under the cabin sole. Were there cross members to which the liner was glued. What were the crossmembers made of? Glassed in wood, Solid glass? I would have thought that any water that collects under the liner would end up in the keel sump. But when you feel around the sump opening it seems to be glued up all around. Anyone know for sure?
