Hello all, Since we have our 500da we have a lot of moisture and leaks in our boat. I almost rebedded everything on the deck and solve a lot of leaks but still we have moisture especially under the gangway above the ceiling around the back plates from the bow rail. I completely dried the area around the back plate and spray water on the deck around the foot of the bow rail but no drips of water coming in. After a while all drips around the back plate. First I thought the water comes from the front of the deck and went slowly his way to the lowest point but that was not the thing. Around 2 foots of the bow rail I have some spider cracks in the gelcoat, but that don’t explain the moisture around the other back plates. is it possible that the back plates are a thermic cold/heat bridges that causes so much moisture? If so, what’s the best solution to solve this problem? I was thinking to spray foam over the backplates. I hope somebody experience the same and solve this problem.
