I recently purchased a Canadian boat, and found out some things that might prove useful. Not the exact situation, but hopefully I can help a bit. The boat I purchased was located in
Alaska, and the owner had it registered in Canada. My bank wouldn't give me a loan for an international
purchase, so the owner registered the boat in
Alaska (for about $26). The state of Alaska doesn't title
boats, so I don't know if he showed his Canadian registry or his bill of
sale. Probably either would have worked. The bill of
sale satisfied my bank, but only because there were no titles available in this state. Once he registered it in the state, there were no hangups. I had a bill of sale from him, and possession of the boat. I just needed the bill of sale to register it in my name. Of course, not knowing which state you reside in, the laws may differ. Check with the DMV (check out
Boat Registration Procedure, Forms, & Information - DMV Guide for your state's regulations). Good luck!
