I’ve had both
teak and
fiberglass decks.
My first
boat had
teak decks on
plywood. It was a newish
boat, so we didn’t have any immediate problems. I used to
varnish the cover boards and king planks and it looked fabulous! After a few years in the Mediterranean’s temperate climate some of the caulking started to
lift and it was a slow, hands and knees job to scrape it out and re-caulk it. We also had
leaks, mainly where the cover boards met the bulwarks. This is a difficult place to seal.
My
current boat has a
fiberglass deck, which is also very hot on the feet in
Florida, but it doesn’t leak.
For me the only benefit for real teak is appearance.
I’ve had quotes for false teak glued on at around $18,000, so that’s out the window. It does look good but is very heavy, as is real teak.
So I’m looking into actually painting sections a light grey, then highlighting with black caulking stripes to simulate planks. I’ve seen it done and it is very striking, but a big job on a fifty footer.
If you buy an old boat with teak decks have it surveyed properly.
Ultimately it’s just a matter of choice, and what you are prepared to put up with.
