Another observation that is no surprise, smaller boats get used more.
It is obvious from the fouling at the waterlines that boats less than
30' get used far more than the big boats.

No, it's not a surprise. A small boat is less status symbol more
something to enjoy -- regularly.

I guess your boats less than 30ft... am I right ?
