there is no sales tax unless you bought the boat recently. After 90 days they want you to register it. Even if it is documented. You don't have to put your numbers on the boat, but just pay the registration fee.

My 1976 boat is classified as an antique and the fees are very low. The old inflatable dink is more to register. Before I found out about the antique classification, my boat was only 50 bucks a year to register, now it is about 5 bucks.

good luck.
