Rhapsody was hauled at Borden Light Marina on 15 October for the season. Last spring a moisture meter was used to check the deck and hull. The news was not good. The entire stbd side below the waterline is wet. There are also some wet spots on the deck. The transom sounds hollow and is delaminated.
After hauling, the bottom was pressure washed and inspected. For the first time ever, blisters were showing on the stbd side on the bottom over about a 4 foot area. These were not there last spring, and must
be forming from moisture inside the core since the entire bottom was redone with new barrier coat two years ago. On Friday 17 October, the blisters were lanced to drain. They were opened up with a sanding disk on an angle grinder, then the area around each blister faired with an orbital sander. In the sequence of photos, you can see the depth of the barrier coat (4 layers alternate white/grey). Plan is to recore the area behind the blisters from inside the boat. I'll be borrowing a moisture meter next week and will map the readings on the hull.
