Where to register your boat and what documents you need

In Massachusetts, you register a boat through the Registry of Motor Vehicles (RMV), the same agency that handles car registration. You can register in person at any RMV branch, by mail, or online through the RMV website for certain boat types. The process takes longer than car registration because the RMV verifies the boat's hull identification number (HIN) and ownership history before issuing your registration.

You will need to bring or submit: a completed process for Boat Registration (Form 34E), proof of ownership (bill of sale, manufacturer's certificate of origin, or previous registration), your Massachusetts driver's license or ID, and proof of Massachusetts residency if your ID does not show a current address. If the boat is financed, you may need a lien release or written permission from the lienholder. The RMV will also require the boat's hull identification number, which is permanently stamped into the hull near the transom or on the manufacturer's plate.

Key Takeaways

  • Massachusetts requires registration for any motorized boat or sailboat over 16 feet, and the Registry of Motor Vehicles handles all registrations.
  • You need a bill of sale or manufacturer's certificate of origin, your driver's license, and proof of Massachusetts residency to register.
  • Registration costs vary by boat length and type, and you can register online, by mail, or in person at an RMV branch.
  • Your registration is valid for one or two years depending on the boat type, and you must renew before the expiration date to legally operate.
  • If your boat is financed, the lender's name appears on the registration and you need their written consent to sell or transfer the boat.

Who must register a boat in Massachusetts

Any boat with a motor must be registered, regardless of size. This includes powerboats, jet skis, and sailboats with auxiliary motors. Sailboats without motors do not require registration unless they are over 16 feet in length. Canoes, kayaks, and other non-motorized boats under 16 feet are exempt.

You must register before you operate the boat on Massachusetts waters. The registration number must be displayed on both sides of the hull in characters at least three inches tall. Operating an unregistered boat carries a fine and can result in the boat being seized by the Massachusetts Environmental Police.

Registration costs and how long it lasts

Registration fees depend on the boat's length and whether it is motorized. The RMV charges a base fee plus a fee per foot of length. A 20-foot motorboat costs more than a 16-foot sailboat, and the exact amount varies year to year. You can find the current fee schedule on the RMV website or by calling your local RMV branch.

Registration is valid for either one or two years, depending on the boat type and when you register. Most motorboats receive a two-year registration, while some smaller boats or those registered mid-year may receive one-year registrations. Your registration sticker shows the expiration month and year. You must renew before that date or you cannot legally operate the boat.

How to register online, by mail, or in person

Online registration is available through the RMV website for boats that were previously registered in Massachusetts and have no outstanding liens. You will need your previous registration number and the boat's HIN. The process takes a few minutes and you can pay by credit card. Your new registration arrives by mail within two weeks.

Mail registration works for new boats and transfers of ownership. Complete Form 34E, gather your documents, and send them to the RMV address listed on the form along with a check or money order. Processing takes three to four weeks. Include a self-addressed stamped envelope if you want the documents returned to you.

In-person registration at an RMV branch is the fastest option if you need the registration when ready. Bring all original documents, your ID, and a check or card for payment. The RMV will verify the HIN on the boat if it is present, and you can walk out with your registration sticker the same day. Some branches require an appointment; check the RMV website for your local branch's hours and appointment policy.

What happens if the boat has a lien or is financed

If you financed the boat, the lender holds a lien on it, meaning they have a legal claim to the boat until the loan is paid off. The lender's name and address must appear on the registration. You cannot sell, transfer, or remove the registration without the lender's written consent.

When you explore for registration, the RMV will ask whether the boat is financed. If it is, provide the lender's name and address exactly as it appears on your loan documents. Once the loan is paid off, contact the lender and ask for a lien release letter. Bring this letter to the RMV or mail it with a renewal form to have the lien removed from your registration.

Renewing your boat registration

You can renew your registration online, by mail, or in person using the same methods as initial registration. Online renewal is available if there are no changes to the boat's information and no outstanding liens. You will receive a renewal notice in the mail about 30 days before your registration expires.

If you miss the expiration date, you cannot legally operate the boat until you renew. The RMV may charge a late fee in addition to the renewal fee. If your boat will not be used for an extended period, you can request a non-operation exemption from the RMV, which temporarily suspends your registration and may reduce fees. Contact your local RMV branch for details on how to request this.

Transferring boat ownership or changing registration information

If you sell the boat, the new owner must register it in their name. Provide the buyer with a bill of sale signed by both of you, and keep a copy for your records. The buyer will need this bill of sale plus their own ID and proof of residency to register. If the boat has a lien, the lender must release it before the sale is complete, or the new owner cannot register it.

If you move to a different Massachusetts address, update your registration by mail or in person. If you move out of Massachusetts, you must cancel your registration. Contact the RMV to find out whether your boat can be registered in another state or whether you need to surrender your Massachusetts registration first.

Frequently Asked Questions

Do I need insurance to register a boat in Massachusetts?

Massachusetts does not require boat insurance to register, but your lender will require it if the boat is financed. Many marinas and launch ramps also require proof of insurance before allowing you to use their facilities. Liability insurance protects you if your boat damages another boat or injures someone.

What is a hull identification number and where do I find it?

The HIN is a 12-character code permanently stamped into the hull, usually near the transom on the starboard (right) side or on the manufacturer's plate inside the boat. It works like a vehicle identification number for cars. If the boat is old or the HIN is damaged, the RMV may require a physical inspection before registration.

Can I register a boat I built myself?

Yes, but you will need a bill of sale or a statement of origin from the manufacturer of the hull kit. If you built it entirely from scratch, contact the RMV to ask what documentation they will accept. You may need a hull inspection or a statement from a marine surveyor before the RMV will issue a registration number.

What happens if I lose my registration sticker?

Contact the RMV and request a duplicate sticker. You will need to provide your registration number and proof of identity. There is usually a small replacement fee. Until you receive the new sticker, you should not operate the boat on public waters, as the registration number must be visible.

Can I register a boat with an out-of-state title?

Yes. Bring the out-of-state title or registration, your bill of sale if you recently purchased it, and your Massachusetts ID and proof of residency. The RMV will process the registration and issue a Massachusetts registration number. If the boat has a lien from an out-of-state lender, provide their information and a copy of the lien release when the loan is paid off.
