About half the boats at my marina are fiberglass. The only maintenance they need is cosmetic, and there are many who skip it and many who polish it.

The other boats are metal. As I write this I am trying to remember if it’s aluminum or galvanized or stainless. There is a popular brand, anyway. The metal boats are popular because it is a fashion thingy to not keep them clean.

The more expensive marinas have bigger proportions of polished boats and teak decks.

Anyway, as a fiberglass boat owner, I’m not recognizing the constant maintenance thingy. Nobody’s told us boat owners! :)
