Actually it is. Most boat owners belong to SeaTow or BoatUS, they are the AAA to the boating world.
While that is true that they are the AAA for boating, IIRC their coverage does NOT cover boats taking on water, partially submerged, or abandoned.
So in this situation, they might call a contractor for a wrecked or submerged boat - I don't believe that SeaTow or BoatUS would cover reclaiming this particular boat in this situation. That's not what the insurance if for :moo:

"Salvage is not covered under membership :Salvage Operations: Salvage operations, including, but not limited to, vessels abandoned, wrecked, beached, on fire, damaged by fire, taking on water, sinking, sunk, previously sunk, in the surf or surf line, or in any other state of peril, are not privileges of membership.

"The distinction between towing and salvage is reflected in the different types of programs available to boaters. Towing assistance, like the pre-paid service available to BoatUS members from the TowBoatUS fleet, provides help for breakdowns and light groundings. The far more expensive salvage claims are covered only by yacht insurance policies."
