Around here (upstate NY), pontoon boats tend to be owned by the same people
who think a K-car is just a bit too wild.

Folks around here are discovering that a pontoon boat makes a pretty good back
bay fishing boat if you set it up center console and toss all of that
furniture.
I use the truck tool boxes for my gear.
Carpet on glued top of the box makes a good walking surface. When granny wants
to go for a ride, just bring along a lawn chair.
That makes this a very low maintenance boat.
One advantage of a pontoon is that you can mount the engine a lot higher so it
runs "on the step" with the cavitation plate just under water and when it sets
down it is only a few inches below that. That makes a boat that will run in a
bit over a foot of water at idle speed without tearing up the bottom. Not many
flats boats (none?) can do that.
