Rollyn,
Here in the US, some states have a Department of Natural Resources, or DNR, that handles boat registration for that state. This agency may be named different in some states, but doing a google search for "Department of Natural Resources" comes back with sites from many states. It is a federal requirement that the boat be either documented or registered in the state of principle use. I did not mean to imply that DNR was a federal agency, since as you say, it is a state agency. I put "US" in the sentence to indicate that I'm going through "the bureaucracy" chain in the US. Sorry if I was unclear.
I have never documented a boat, so I don't know if that would be easier/quicker than going through the state registration process. I guess while I'm waiting, I'll do some research into it.
Thanks,
Chris
