Fibreglass boat hulls have constant ongoing maintenance and repair cycles.
Hell, just last week I was watching a video about how abysmal the material has been for the wind turbine industry after it tips apart from hail stones.
Sure, theyre moving at 100 mph but I don't see why people would think building bridges out of this stuff is a good idea.
I think your mental model of wind turbine sizes is a bit off: the rotation speed is basically dictated by the need to keep blade tips moving slower than the speed of sound, which is why you see newer/larger turbines going slower than older/smaller turbines.
Most modern turbines operate with tip speeds around 200m/s, corresponding to around 450 mph.
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! :)
