Before glassing in the next section of plywood decking, I glassed in a section of 3" PVC pipe cut in half to allow the flow of any bilge water from the bow area directly back. The original design had a removable deck panel presumably for under-floor storage. It was always the collection point for any rain or splash water that made its way into the bilge; useless for storage. I intend to fill the section with flotation foam so the glassed in pipe will allow drainage and protect the foam.
