New Hampshire Boat (Vessel) Bill of Sale Form

To register a watercraft, you can elect to mail in the required information or gather the following documentation to hand-deliver at your nearest New Hampshire DMV facility:

• Bill of Sale, including the date of sale, vessel description, and the signatures and addresses of both the buyer and seller.
• Boat Registration Application (RDMV 612)
• Payment for registration fees.
• Photo identification.
• Verification of Vessel Identification, if the boat is homemade or does not have a proper Hull Identification Number.

Out-of-State Purchase

• Out-of-state registration, if available or needed to support proof of ownership.

A vessel registered in another state may be used on New Hampshire waters for 30 consecutive days or less without New Hampshire registration. After that, New Hampshire registration is required.
