I'm just curious if anyone knows the lifespan of teak decks. I looked at a leaky teaky in michigan several months ago. The boat is stored inside during the winter and the decks are very dark as if they had been oiled. I saw no bungs popping up or missing. I dont know how thick the decks should be. Should I pop out several plugs from various spots on the deck to check, or would that create a problem? The boat is circa 1978 and looks as good in person as it does online. Thanks for any insight.
A 78 'leaky teaky' with an original teak deck in good order would be an exceedingly rare bird.
20 to 30 years for an average job with average use and maintenance would be my best guess.
