Massachusetts boat registration is handled by the Registry of Motor Vehicles, and the process depends on whether your boat has a motor and how you plan to use it

Massachusetts requires registration for most motorboats, sailboats with auxiliary motors, and personal watercraft. The Registry of Motor Vehicles (RMV) issues boat registrations, which are valid for one year from the date of issue. Non-motorized sailboats and canoes do not require registration in Massachusetts, though some towns may have local mooring or launch fees.

The registration process itself is straightforward: you submit proof of ownership, pay the fee, and receive a registration certificate and decals. The fee varies based on boat length and type. You'll need to complete this before operating your boat on Massachusetts waters, and you must display the registration decals on both sides of the hull near the bow.

Key Takeaways

  • Motorboats, sailboats with motors, and personal watercraft must be registered with the Massachusetts RMV; non-motorized sailboats do not.
  • You need proof of ownership (bill of sale, manufacturer's certificate, or previous registration) and a completed process form to register.
  • Registration fees are based on boat length and range from under $50 for small boats to several hundred dollars for larger vessels.
  • Registrations are valid for one year and must be renewed annually; you receive decals that must be displayed on the hull.
  • You can register in person at an RMV branch, by mail, or online through the RMV website for certain boat types.

What documents you need to bring or submit

To register a boat in Massachusetts, you must provide proof of ownership. This can be a bill of sale from the previous owner, a manufacturer's certificate of origin if the boat is new, or your previous boat registration if you're renewing or transferring ownership. The document must show the hull identification number (HIN), which is a unique code stamped or attached to the boat's hull.

You'll also need to complete the process for Boat Registration form (available from the RMV website or at any RMV branch). If you're registering a boat you've purchased from a dealer, the dealer may handle some of the paperwork for you, but you should verify what you still need to submit. If the boat has a lien against it (meaning a bank or lender has a claim on it), you may need to provide documentation showing the lienholder's name and address.

Registration fees and how they're calculated

Boat registration fees in Massachusetts are based on the length of the boat. The RMV measures from the tip of the bow to the stern (back) to determine the fee category. Boats under 16 feet typically cost less than $50 to register, while boats between 16 and 26 feet cost more, and larger vessels have higher fees. Personal watercraft (jet skis) have a separate, usually lower fee structure.

The fee covers a one-year registration period. When your registration expires, you renew it annually by paying the renewal fee and providing updated information if anything has changed. Some towns in Massachusetts also charge local mooring fees or launch fees separate from state registration, so check with your town's harbormaster or marine department if you plan to moor or launch from a town facility.

Where and how to register your boat

You can register a boat at any Registry of Motor Vehicles branch in Massachusetts. Walk-in registration is available during business hours, and you can expect the process to take 15 to 30 minutes if your paperwork is complete. The RMV also accepts mail-in registrations; you can send your completed process, proof of ownership, and payment to the RMV address listed on their website.

Online registration is available through the RMV website for certain boat types and situations, though not all registrations can be completed online. If you use an online system, you'll still need to mail in or bring original documents to verify ownership. After your process is processed, you'll receive a registration certificate and two decals by mail. The decals must be applied to both sides of the hull near the bow, and they must be visible and not obscured.

How long registration takes and when it expires

If you register in person at an RMV branch with complete paperwork, you typically receive your registration certificate and decals on the same day or within a few days. Mail-in registrations usually take one to two weeks to process, depending on how busy the RMV is. Online registrations, where available, may be faster, but you still need to submit original documents by mail to complete the process.

Your registration is valid for one year from the date it is issued. The expiration date is printed on your registration certificate. You must renew before that date to continue operating your boat legally. The RMV typically sends renewal notices by mail about 30 days before expiration, but it is your responsibility to renew on time. Operating an unregistered or expired boat can result in fines.

Special situations: transfers, replacements, and out-of-state boats

If you buy a used boat from another Massachusetts owner, you'll need to transfer the registration into your name. Bring the previous registration, your bill of sale, and proof of ownership to an RMV branch. If you're moving to Massachusetts from another state and bringing a boat with you, you must register it with the Massachusetts RMV within a certain timeframe. Contact the RMV to learn the specific requirements for your situation, as they vary depending on your residency status and the boat's previous registration.

If your registration certificate or decals are lost, damaged, or stolen, you can request a replacement from the RMV. There is usually a small fee for replacement decals. If you sell your boat, notify the RMV in writing so the registration is transferred out of your name and you are no longer liable for it. Some dealers handle this notification for you, but confirm that they have done so before you leave the transaction.

Boats that don't require registration

Non-motorized sailboats and canoes do not require state registration in Massachusetts. However, some towns require local registration or permits for boats launched from town facilities, so check with your local harbormaster. Boats used exclusively for racing may have different registration requirements; contact the RMV if your boat falls into this category.

Rental boats and boats operated by commercial fishing operations have separate registration categories and rules. If you operate a boat for commercial purposes, contact the RMV directly to understand what registration and licensing you need.
