My yard wants me to replace the teak deck on my 1983 Passport 40. I'm unclear as to whether it really leaks or if it's chainplates or another source that would be less expensive to repair. I'm unclear whether deck leaking has been a problem for Passport 40's in general. So far I've not read about delamination problems in the 40's. Also, does anyone know what year Passport 40's went to airex cored decks from plywood? An airex cored deck should be less susceptible to delamination from leaks, I assume, but again I'm uncertain that's true. What's others experience with Passport 40's teak decks and leaks? Appreciate any help. Also, as a postscript I've taken scrupulous care of the teak with semco every year. Literally no bungs have eroded either. In other words, the teak still looks beautiful, which adds to my angst about removing it.
