What You Need to Register a Boat in Massachusetts

Massachusetts requires you to register any boat with a motor, regardless of size, before you operate it on state waters. The registration process is handled by the Massachusetts Division of Marine Fisheries, which is part of the Department of Fish and Game. You can register in person at a marine fisheries office, by mail, or online through the state's system — the online route is fastest if you have all your documents ready.

The basic requirement is straightforward: you need proof of ownership (a bill of sale or title), proof of your identity, and proof that the boat meets safety standards. If the boat is financed, your lender's name goes on the registration. Registration lasts three years, and you renew it before expiration by submitting a renewal form and the fee.

Key Takeaways

  • Any motorized boat in Massachusetts must be registered with the Division of Marine Fisheries before you use it, even if it is only a small outboard motor.
  • You will need a bill of sale or title, a photo ID, and proof the boat passed a safety inspection or meets exemptions.
  • Online registration through the state system is the fastest method if you have your documents scanned and ready.
  • Registration lasts three years, and renewal requires submitting a form and paying the fee before the expiration date.
  • If your boat is financed, the lender's information must be included on the registration.

Documents You Need Before You Start

Gather these items before you contact the Division of Marine Fisheries or visit an office. You will need proof of ownership — either a bill of sale from the previous owner or a title certificate if the boat is titled in Massachusetts or another state. If you are the original owner and built the boat yourself, bring documentation of construction and materials.

You also need a photo ID showing your current address. A driver's license works; a passport does not unless it includes your address. If your address on the ID does not match where you live now, bring a second document showing your current address — a utility bill, lease, or mortgage statement dated within the last 60 days.

Finally, you need proof that the boat meets safety standards. Most boats pass inspection automatically if they have a manufacturer's hull identification number (HIN) and were built after 1972. If your boat was built before 1972, is homemade, or does not have a HIN, you must have it inspected by a marine surveyor or the Division of Marine Fisheries before registration. The inspection confirms the boat is seaworthy and the HIN is legitimate.

How to Register Online or by Mail

The fastest route is the online system at mass.gov/eea under the Division of Marine Fisheries section. You will enter your boat's HIN, your personal information, and upload scans of your proof of ownership and ID. The system generates a registration number when ready, though the physical certificate arrives by mail within two weeks. You can begin operating the boat once you receive the confirmation number online — you do not have to wait for the paper certificate.

If you prefer to register by mail, read the registration form from the Division of Marine Fisheries website, fill it out completely, and mail it with copies of your documents and the registration fee to the address listed on the form. Processing takes three to four weeks by mail. Include a self-addressed stamped envelope if you want the certificate returned quickly.

For in-person registration, visit a Division of Marine Fisheries office with your original documents. Offices are located in Boston, New Bedford, and Gloucester. Bring the originals — staff will make copies for you. In-person registration takes about 30 minutes, and you leave with a temporary registration slip valid for 30 days while the certificate is printed.

Registration Fees and What They Cover

The registration fee depends on the boat's length. Boats under 16 feet cost less than boats 16 to 25 feet, which cost less than boats over 25 feet. The exact amounts vary slightly year to year, so check the Division of Marine Fisheries website for the current fee schedule. The fee covers three years of registration — you do not pay annually.

The registration includes a decal that you must display on the boat. The decal goes on the hull, usually on the side near the stern. It shows your registration number and expiration year. You are required by law to display it; operating without a visible decal can result in a citation.

Renewing Your Registration Before It Expires

You will receive a renewal notice by mail about 60 days before your registration expires. The notice includes a renewal form and instructions. You can renew online, by mail, or in person using the same methods as initial registration. Renewing online takes five minutes if you have your registration number and the renewal fee ready.

Do not wait until the expiration date to renew. If your registration lapses, you cannot legally operate the boat, and you may face a fine if you are caught on the water without current registration. If you miss the important date, you must re-register as a new boat rather than renew, which takes longer and may cost more.

Boats That Do Not Need Registration

A few categories of boats are exempt from registration in Massachusetts. Non-motorized boats — sailboats without an engine, rowboats, canoes, and kayaks — do not need to register. Boats registered in another state that are temporarily in Massachusetts waters (less than 60 consecutive days) do not need a Massachusetts registration, though you should carry proof of your out-of-state registration.

Boats owned by the federal government, state government, or a municipality are exempt. Commercial fishing vessels have a separate licensing process through the Division of Marine Fisheries and do not use the standard registration system. If you are unsure whether your boat is exempt, contact the Division directly — they can answer in one call.

What Happens If You Register a Boat You Do Not Own

The person whose name appears on the registration is the legal owner for purposes of Massachusetts law. If you register a boat in your name but do not actually own it, you can face fraud charges. If the boat is financed, the lender's name must appear on the registration as a lienholder — this protects their interest if the boat is sold or seized.

If you buy a boat and the previous owner has not transferred the title, you cannot register it in your name. The seller must sign the bill of sale or title over to you. If the seller refuses or has disappeared, you will need to work through a lawyer or the Registry of Motor Vehicles to establish ownership before the Division of Marine Fisheries will register it.

Frequently Asked Questions

Do I need to register a boat with just a trolling motor?

Yes. Massachusetts requires registration for any boat with any motor, including electric trolling motors. The size of the motor does not matter — if it propels the boat, the boat must be registered.

What if I buy a used boat and the seller lost the title?

Contact the Division of Marine Fisheries to ask about a lost title replacement. If the boat was previously registered in Massachusetts, they can issue a duplicate. If it was registered in another state or never titled, you may need a bill of sale and a statement from the seller confirming they own it. The Division will tell you what documents they need.

Can I register a boat if I do not have a permanent address in Massachusetts?

You must have a Massachusetts address to register a boat in the state. If you live out of state but keep the boat in Massachusetts, you will need to register it in your home state instead. Some states allow non-resident registration if the boat is moored or docked in their waters — check your home state's rules.

How long does online registration actually take?

The online system generates a confirmation number and temporary registration within minutes. You can use that number to operate the boat when ready. The physical certificate arrives by mail in one to two weeks, but you do not need to wait for it.

What if my boat's HIN is damaged or missing?

A missing or illegible HIN requires an inspection by the Division of Marine Fisheries or a certified marine surveyor before you can register. Schedule an inspection appointment through the Division. They will verify the boat's identity and either confirm the HIN or issue a new one if the original cannot be recovered.
