What about all the teak on the deck? Does it take a lot more maintenance than a fiberglass deck?
When it comes time to replace it, it is expensive. Other than that, not so much. Remember that it is not the kind of teak that you are varnishing or oiling. I wash it with water, boat soap and a bit of cascade two or three times a year.
The conventional wisdom is that it can need to be replaced every twenty years (although some people go much longer). Our deck was just replaced by the prior owner.
