Minnesota requires registration for most boats, jet skis, and other watercraft you operate on public water

If you own a boat, jet ski, or other motorized watercraft in Minnesota, you need to register it with the state before you can legally use it on public waters. Registration is handled by the Minnesota Department of Natural Resources (DNR), and the process involves submitting paperwork, paying a fee, and receiving registration numbers that you display on your vessel. Non-motorized boats like canoes and rowboats do not require registration, but anything with a motor does.

The registration process takes a few weeks from the time you submit your paperwork. You can register in person at a DNR office, through an authorized agent (usually a bait and tackle shop or marina), or by mail. The fee depends on the length and type of your watercraft and ranges based on horsepower for motorized vessels.

Key Takeaways

  • Motorized watercraft must be registered with the Minnesota DNR before operating on public water; non-motorized boats do not require registration.
  • You will need proof of ownership (title or bill of sale), proof of identity, and payment for the registration fee when you register.
  • Registration can be completed in person at a DNR office, through an authorized agent like a marina, or by mail.
  • Your registration certificate and decals must be carried on the boat, and the registration numbers must be displayed on the hull.

What documents you need to register

Before you register, gather proof that you own the watercraft. If the boat is new and has never been registered in Minnesota, bring the manufacturer's statement of origin or a bill of sale. If you are transferring registration from another state or taking over an existing Minnesota registration, you will need the title or previous registration certificate.

You will also need a valid form of identification — a driver's license, passport, or state ID card. If someone other than the owner is registering the boat, you may need a power of attorney or notarized authorization, depending on the DNR agent you work with. Contact your local DNR office or authorized agent ahead of time to confirm what they require, since requirements can vary slightly.

Registration fees and how long registration lasts

Minnesota registration fees are based on the length of your watercraft and, for motorized boats, the horsepower of the engine. A boat under 16 feet with a motor under 10 horsepower costs less than a 25-foot boat with a 200-horsepower engine. The DNR publishes a fee schedule on its website, and authorized agents can tell you the exact cost when you contact them.

Registration is valid for three years from the date it is issued. You will receive a renewal notice in the mail before your registration expires, and you can renew by mail, in person, or through an authorized agent. If you sell the boat, the new owner must register it in their name; the registration does not transfer automatically.

Where to register in person or by mail

The Minnesota DNR has regional offices throughout the state where you can register in person. You can find the office nearest you on the DNR website by searching for "watercraft registration" and your county. Walk-in hours vary by location, so call ahead or check online before you go.

If you prefer to register by mail, send your completed registration form, proof of ownership, and payment to the DNR office that serves your area. Mail registration typically takes two to four weeks. You can also register through an authorized agent — a bait and tackle shop, marina, or boat dealer — which often processes registrations faster than mail and may offer evening or weekend hours.

Registration decals and hull numbers

When your registration is approved, the DNR will mail you a registration certificate and two decals. The decals display your registration number and must be attached to the hull of your boat, one on each side, in a location that is clearly visible. The registration certificate must be carried on board whenever you operate the watercraft.

If your boat already has a hull identification number (HIN) — a unique code assigned by the manufacturer — the DNR will use that for your registration. If it does not have one, the DNR may assign a number. Never paint over or remove the HIN or registration numbers; doing so is illegal and can result in a fine.

Renewing your registration

Your registration is good for three years. About 30 to 60 days before it expires, you will receive a renewal notice in the mail. You can renew by returning the notice with payment, by going in person to a DNR office or authorized agent, or by mail. Renewing is simpler than the initial registration because you do not need to provide proof of ownership again — just your renewal notice and payment.

If you miss the expiration date, you can still renew, but you may face a late fee. Operating an unregistered watercraft on public water is illegal and can result in a citation and fine. If you have not received a renewal notice 60 days before expiration, contact the DNR office that issued your registration to confirm your address is correct.

What happens if you buy a used boat or move to Minnesota

If you buy a used boat from someone in Minnesota, ask the seller for the current registration certificate. You will need to transfer the registration into your name by submitting a form to the DNR along with proof of ownership (the bill of sale or title) and proof of identity. The transfer process is faster than a new registration and usually takes one to two weeks.

If you move to Minnesota with a watercraft registered in another state, you must register it in Minnesota within 90 days. Bring your out-of-state registration certificate, proof of ownership, and identification to a DNR office or authorized agent. The DNR will issue a new Minnesota registration and decals.

Frequently Asked Questions

Do I need to register a canoe or kayak?

No. Minnesota only requires registration for motorized watercraft. Canoes, kayaks, rowboats, and sailboats without motors do not need to be registered. However, all passengers on any watercraft must wear a Coast Guard-approved life jacket.

What if I lose my registration certificate or decals?

Contact the DNR office that issued your registration and request a replacement. You will need to pay a small replacement fee. In the meantime, carry proof of your registration number (a photo of your certificate or a copy of your renewal notice) in case you are stopped by a conservation officer.

Can I register a watercraft if I do not have a title?

If the boat is very old or was homemade, it may not have a title. Contact your local DNR office to ask about alternative forms of proof of ownership. You may be able to use a bill of sale, a notarized statement, or other documentation, depending on the boat's history.

What if I sell my boat before the registration expires?

Notify the DNR in writing that you have sold the boat and provide the buyer's name and address. The buyer must then register the boat in their name. You are not responsible for the boat once the DNR receives notice of the sale, but do not leave the decals on the hull — remove them or cross them out so the new owner knows to register it.

Is there a penalty for operating an unregistered watercraft?

Yes. Operating an unregistered motorized watercraft on public water in Minnesota is illegal and can result in a citation, fine, and confiscation of the boat. The fine varies depending on the violation but can be substantial. Always keep your registration current and carry your certificate on board.
