Those of us not versed in swamp culture.......what's wrong with it?
it creates wave action that isn't there.
the wave action from the boat's wake pushes even more water than is already there.
which both raises the water level and moves things around that float.
depending on the speed of the boat, those wakes can sometimes have waves over a foot tall.
so anything less than 12" above the current flood line that was dry and salvageable is now being flooded.
and debris that was just lazily drifting along the surface is now being forcibly propelled in the direction of the wake is traveling and will bang against anything in the way.
so hypothetically:
your house (and maybe a car) was spared the actual flood by 4" or so. You got lucky.
then some asshole comes roaring through the street in an airboat.
that wave he's pushing flows right into your home that WAS spared by the flood.
and your car that was lucky now both has water in it and a 4x4 with part of somebody's awning attached also slams and scrapes along the side of you car at the peak of every wave.
most of your flooring now needs to be ripped well past what got flooded (so entire subfloor can dry out before replacing the flooring)
sheet rock walls need be changed to a height at least several inches or a foot above the water line (water travels up the insulation inside your walls, so all that needs to be replaced too). Anything electrical, outlets, etc., will also now need to be replaced because those don't handle salty water very well.
Your central AC unit that only had water in the drip pan now just had the motor and compressor go under salt water, so that will need replacing.
your car that only need a good spraying down with fresh water now needs all of the interior carpeting replaced, and wiring or connections that got wet need to be replaced. Oh and you now need body work and a paint job.
You just went from thanking your lucky stars for being spared to now having tens of thousands of dollars worth of damage and extended the amount of time your home is not livable, and your car is also fucked up.
all because of a thoughtless prick that didn't need to be running around in an airboat.
Would be a different story if water was 10' deep everywhere and you were rescuing people from drowning.
A. you're saving lives and not just "patrolling" a neighborhood.
B. water that deep has already fucked up everything and you're not really adding to the damages in that situation.
