How to register a boat in Minnesota
License before you operate; transfers within 15 days
A watercraft must be licensed before it is operated on Minnesota waters. When you buy a boat that is already titled or registered in Minnesota, the transfer application must be filed within 15 days of the sale. You can license in person at any deputy registrar of motor vehicles (the same office that handles your car tabs), at the DNR License Center in St. Paul, or by mail; renewals can also be done online at mndnr.gov/licenses.
Gather your boat details and proof
You need the hull length (measured bow to stern in a straight line, excluding bowsprits and motor brackets), the hull material and propulsion type, the model year, the Hull Identification Number, and the Manufacturer's Statement of Origin (MSO) for a new boat. Bring a sales receipt showing sales tax was paid. For a used titled boat, bring the assigned watercraft title and a completed transfer application.
Pay the three-year fee
Minnesota watercraft licenses run for a three-year term. The amount is your base fee by type and length plus an invasive-species surcharge, a small per-transaction aquatic-invasive-species fee, and a filing fee. Sales or use tax on the purchase is handled separately (private-party sales are not taxed at the counter).
Display your license number and decals
Motorized watercraft display the license number — in the format "MN" plus digits plus letters — on each side of the forward half of the hull in block characters at least 3 inches high, with the "MN" separated from the numbers by a 3-inch space and the validation decal placed within 4 inches of the number toward the stern. Non-motorized craft display only the decal, with no 3-inch numbers required. Documented vessels are not licensed by Minnesota at all (see below).
Minnesota registration fees
Minnesota sets a three-year base fee by watercraft type and length. On top of the base fee you pay an invasive-species surcharge that scales with the boat, a $1.50 per-transaction aquatic-invasive-species fee, and a $7.00 filing fee, so the amount at the counter is meaningfully higher than the base figures below. New fees took effect January 1, 2026.
| Class | Vessel length | Base fee |
|---|---|---|
| Non-motorized over 10 ft (canoe, kayak, paddle craft) | Over 10 ft | $23.00 |
| Sailboat 19 ft or under | Up to 19 ft | $23.00 |
| Pleasure watercraft | Under 17 ft | $36.00 |
| Pleasure watercraft | 17 ft to 19 ft | $59.00 |
| Pleasure watercraft | Over 19 ft to under 26 ft | $113.00 |
| Pleasure watercraft | 26 ft to under 40 ft | $164.00 |
| Pleasure watercraft | 40 ft and over | $209.00 |
| Personal watercraft (jet ski) | Any | $85.00 |
Three-year base fees effective January 1, 2026; each also carries an invasive-species surcharge (roughly $20–$62 by size), a $1.50 aquatic-invasive-species fee, and a $7.00 filing fee. A watercraft title is $22.00 including filing. Confirm the current total with a deputy registrar or the DNR License Center.
Titling in Minnesota
Minnesota titles watercraft, but only above a size threshold: a certificate of title is required for watercraft more than 16 feet long. Boats 16 feet or shorter, boats manufactured before August 1, 1979, canoes and kayaks, rowing shells, and a rowboat with oarlocks and an outboard under 40 horsepower are all exempt from titling even when they must be licensed.
A federally documented vessel sits outside the state system entirely. Because U.S. Coast Guard documentation is available to vessels of 5 net tons or more and serves as both the ownership record and the operating authority, Minnesota exempts documented watercraft from both licensing and titling — the federal paperwork replaces the state registration rather than supplementing it. That is the opposite of the Florida-style "documented but still registered" arrangement, and the distinction is explained in state registration vs USCG documentation.
HIN requirements
Watercraft built for model year 1973 or later carry a Hull Identification Number, usually on the starboard side of the transom; boats built before November 1972 have a shorter manufacturer serial number instead. The HIN goes on the license application and must match the ownership paperwork — decode any existing hull number with the HIN decoder to confirm the manufacturer and model year before you file.
For a homemade boat, or a boat whose HIN is missing, damaged, or unreadable, the DNR issues a state-assigned Hull Identification through its Hull Identification Assignment form (NA-00469-01). The assigned number must be permanently affixed — carved, burned, stamped, embossed, molded, or bonded so that removal or alteration is obvious — in the specified starboard location, with an identical duplicate placed in a hidden interior spot under a fitting. Questions about homemade boats and HIN assignment go to the DNR License Center.
Renewal
Minnesota watercraft licenses cover three calendar years and all expire on December 31 of the final year — a fixed statewide date rather than a rolling anniversary or the owner's birthday. The expiration appears on both the certificate and the validation decals. Renew in person at a deputy registrar or the DNR License Center, by mail, or online at mndnr.gov/licenses, and remove the old decals before applying the new set.
Exemptions
Non-motorized watercraft 10 feet or shorter are exempt from licensing. Watercraft validly registered in another state or country are exempt as long as they are not kept in Minnesota for more than 90 consecutive days. Also exempt: U.S. Coast Guard-documented vessels (5 net tons or larger), ships' lifeboats, seaplanes, duck boats used during the waterfowl season, rice boats used during the wild-rice harvest, and vessels owned by the federal government. Any motorized craft — even a canoe or kayak with a small motor — must be licensed regardless of length.
Frequently asked questions
Do I have to register my kayak or canoe in Minnesota?
Only if it is longer than 10 feet. A non-motorized canoe, kayak, or paddleboard 10 feet or shorter is exempt. If it is over 10 feet it must be licensed, but it only needs the validation decal — no 3-inch "MN" numbers. Add any motor, however, and it must be licensed no matter how short it is.
Does Minnesota title boats?
Yes, but only watercraft more than 16 feet long. Boats 16 feet or shorter, boats built before August 1, 1979, canoes and kayaks, and Coast Guard-documented vessels are exempt from titling. A watercraft title costs $22.00 including the filing fee.
My boat is Coast Guard documented — do I still license it in Minnesota?
No. Unlike some states, Minnesota exempts documented vessels from both licensing and titling. The federal Certificate of Documentation replaces the state registration, so a documented boat carries no "MN" number and no state title.
How long is a Minnesota watercraft license good for?
Three calendar years. Every license expires on December 31 of the third year — the same date for everyone — and the date is printed on the certificate and the decals. You renew in person, by mail, or online at mndnr.gov/licenses.
My homemade boat has no HIN — what do I do?
Apply to the DNR for a state-assigned Hull Identification using the Hull Identification Assignment form (NA-00469-01). You permanently affix the assigned number in the required starboard location, plus a hidden duplicate inside the hull, before the boat can be licensed.
