How to register a boat in Alaska
Register before principal use in Alaska
Any boat principally used in Alaska must be registered unless it is specifically exempt — this expressly includes barges, sport-fishing-guide boats, tenders, and any boat with a motor. Once you have applied, a copy of your application serves as your registration for up to 60 days or until your new registration arrives.
Apply through the DMV
Register with the Alaska DMV online, by mail to the Anchorage office, or in person at a DMV location. There are no county tax collectors or license agents in Alaska's system — the DMV handles vessels statewide.
Provide proof of ownership
Acceptable proof includes a manufacturer's certificate or statement of origin, a prior state title, a USCG Certificate of Documentation or CG-1261 builder's certification, or a bill of sale. Where documents are missing, file an Affidavit of Boat Ownership (form 848); a title may then issue after three years if ownership is uncontested.
Display your number and decal
An undocumented boat receives an AK number for the bow plus a validation decal. A federally documented vessel is exempt from state numbering but must still display the Alaska registration decal.
Alaska registration fees
Alaska charges a flat registration fee that covers the full three-year cycle — it is based on the type of boat, not its length. There is no state sales tax on the transaction. Titling and duplicate fees are separate.
| Class | Vessel length | Base fee |
|---|---|---|
| Powered boat | Any length (3-year cycle) | $24.00 |
| Non-powered boat (when registration is required) | Any length (3-year cycle) | $10.00 |
| Barge | Any length (3-year cycle) | $75.00 |
Boat title or duplicate title is $20; a replacement registration or decals is $5; lien recording is free. A hull-inspection fee may apply for a state-assigned HIN — confirm the current amount on the DMV fee schedule rather than relying on third-party figures.
Titling in Alaska
Alaska titles boats, but not all of them. Under AS 05.25.056, the owner of an undocumented boat that is subject to registration and is more than 24 feet long must apply for a certificate of title (or a "No Title Issued" registration). For a boat 24 feet or shorter, titling is optional — registration is required, but a title is issued only on request.
Federally documented vessels of any length are exempt from both state titling and state numbering, because the USCG Certificate of Documentation is the ownership record. A documented vessel still must register with the Alaska DMV and display the state decal if it is principally used in Alaska — the "documented but not titled" arrangement explained in state registration vs USCG documentation.
HIN requirements
Boats manufactured after 1972 carry a 12-character hull identification number (HIN). Alaska does not routinely require a hull inspection to register — one is triggered only when there is a discrepancy, such as a HIN that is illegible, absent, or does not match the ownership documents.
A used boat with no HIN, or a homemade boat, must be inspected and assigned a state HIN by a Marine Safety Officer. Alaska issues state-assigned hull numbers with the prefix "AKZ" for these vessels. If your boat lacks ownership paperwork entirely, an Affidavit of Boat Ownership (form 848) starts the process.
Before registering, run any existing hull number through the HIN decoder to confirm the manufacturer and model year match your paperwork.
Renewal
Alaska boat registration is valid for three years and expires at the end of the month in which the boat was first registered. Renewal fees match the initial fees ($24 powered, $10 non-powered, $75 barge). The DMV mails a renewal notice if it has your current address; renew online, by mail, or in person. No formal statutory grace period is published, so renew before the month-end expiration.
Exemptions
Non-powered boats — canoes, kayaks, rowboats — are exempt from registration unless they carry an auxiliary motor or are used as a sport-fishing-guide boat, in which case the motor or guide use is the trigger, not length. A boat validly registered in another state or country may operate in Alaska for up to 90 consecutive days without Alaska registration. Boats owned by the U.S. government or a state (or their subdivisions) are exempt, as are seaplanes, ships' lifeboats, USCG-inspected passenger vessels, and water toys. Federally documented boats of any length are exempt from state numbering and titling but must still register and display the Alaska decal.
Frequently asked questions
Does Alaska title boats?
Yes. An undocumented boat that is subject to registration and is more than 24 feet long must be titled (or registered as "No Title Issued"). A boat 24 feet or shorter can be titled optionally — registration is required either way. Federally documented vessels are exempt from state titling.
Do I have to register a kayak or canoe in Alaska?
No — non-powered craft such as kayaks, canoes, and rowboats are exempt from registration. That exemption ends if you add an auxiliary motor or use the craft as a sport-fishing-guide boat, either of which requires registration.
How long is an Alaska boat registration good for?
Three years. It expires at the end of the month in which the boat was first registered, and the renewal fee matches the original ($24 for a powered boat).
Do I still register my boat in Alaska if it is USCG documented?
Yes, if it is principally used in Alaska. A documented vessel is exempt from state numbering and titling, but it must still register with the DMV and display the Alaska validation decal.
My homemade boat has no HIN — what do I do?
A Marine Safety Officer inspects the hull and assigns a state hull number, which Alaska issues with an "AKZ" prefix. If you also lack ownership documents, file an Affidavit of Boat Ownership (form 848); a title can issue after three years if ownership stays uncontested.
