Interesting post. Last winter I had the teak deck (factory installed from new when I bought my B32 Another Fantasy new in 2002) replaced for exactly the same reason. In most areas the deck was sound but the caulking had started to fail allowing damp to penetrate the deck substrate causing it to lift. I was advised that recaulking was a possibility but no guarantee of a permanent cure so I decided to ‘bite the bullet’ and have the deck replaced. After some deliberation I chose FlexiTeek which was fitted last Spring and I’m really pleased with the outcome, the boat looks as good as new. Expensive but worth it!!
