I have a old buddy in Florida that has a salvage/recovery business that goes and gets boats. Been awhile since he gave me the explanation on how it works but its something like this...
he finds a boat
he calls it in
the owner is notified
if the owner doesn't come get it in a specified time, its my buddies to take.
He's got a storage yard and calls me if he gets a Donzi, Cig, or something else that I may know of a person that'd be interested. The bad thing is that almost none have a trailer to get them anywhere.
