Coast Guard Documentation?
My lender required documentation for my boat as part of the loan process, so I did not have a choice to register with the State. The initial cost of documentation through the USCG was about the same as State registration, however, the one-time fee is good throughout my ownership. Annual USCG renewal is at no additional cost.

I also like the fact that no hull registration sticker is necessary.
