Sorry, I just couldnt help it, even though I should think of other
things.

So...Useless idea #3738

marinas should install boat bottom cleaning systems like car wash
brushes except for the bottom of boats. This would keep down the
slime on boat bottoms and also prevent hard growth if done every now
and then in places without severe fouling. I imagine some sort of
brush system that scrubs your boat bottom like car wash brushes do.
What could they charge for such a service?
