We surveyed a 420 DB today. The survey revealed a small moisture spot on the transom above the stbd trim tab but still below the water line. The moisture meter revealed a semi high reading but the percussive testing was perfect on this spot and the rest of the boat. The boat was out of the water for 24 hours, and the reading was through the bottom paint. Also my understanding is that this is a solid fiberglass boat below waterline. The surveyor did not seem too concerned of the high reading. But did say it is something you should be aware of. I would appreciate any insights you guys might have.
