Squatting at dock

[over40pirate]

Before suggesting what to do, there are some questions.
Is the boat a junker or not?
Does she have a way of contacting him?
How long has the boat been there?

I would do a Documentation and registration search, then put a lien on it.
If the search shows a mortgage holder, contact them, and say the boat is here and abandoned.
Maybe chain it to the dock.
I would hesitate to remove anything, or damage the boat. Paybacks could be hell.
As recommended, contact a salvage company and discuss the problem.
