Found a nice trawler yatch but all the veneers rotted because of a leaky window in the aft cabin anyone know of a good teak supplier.Also could the teak decks leak told they are screwed to the fibreglass.
Yes, teak decks can let in water through fixing screws, so a big BEWARE.
This water doesn't usually come out where it goes in. What it does is soak into the core material of the deck, making the deck heavy, wet, spongy and weak. If you even begin to suspect that the deck may be letting water through check (yourself or surveyor) very carefully the integrity of the deck structure. Repairs can be very expensive. Wet decks are a good reason to walk away, unless the price allows you to get them properly fixed.
