Hawaii Boat Registration Fee Calculator
Registering a boat in Hawaii costs $20–$35 per year, based on length. It's handled by the Hawaii DLNR Division of Boating & Ocean Recreation and renews annually. Non-motorized craft like kayaks and canoes are generally exempt (check local rules for sailboats). Boats with motors — including trolling motors on otherwise unpowered craft — almost always require registration.

Frequently asked questions
Do I have to register a kayak or canoe in Hawaii?
Generally no — unpowered craft are exempt in Hawaii. But the moment you mount any motor, including an electric trolling motor, registration is required.
How often do I renew a boat registration in Hawaii?
Annually.
Do I have to register my boat trailer separately in Hawaii?
Yes — in Hawaii the boat and the trailer are two separate registrations. The boat's fee is above; the trailer registers as a utility trailer with the motor-vehicle agency, priced by the trailer's weight (often a low flat fee or a one-time permanent plate). See our Hawaii trailer registration calculator for that cost.
Do I need a title for my boat in Hawaii?
Yes — Hawaii issues a boat title for a one-time $20 fee, generally required for larger or newer motorized vessels (smaller craft are often exempt). The title is separate from the registration fee shown above.
Do I have to register a jet ski or PWC in Hawaii?
Yes — personal watercraft (jet skis, Sea-Doos, WaveRunners) are motorized vessels, so they register just like boats in Hawaii, usually in the smallest length class. The same Hawaii DLNR Division of Boating & Ocean Recreation handles them, and the same fee schedule applies.
Where do I register a boat in Hawaii?
Boat registration in Hawaii is handled by the Hawaii DLNR Division of Boating & Ocean Recreation. You can generally register in person, by mail, or online, and you'll need proof of ownership (a bill of sale or title) plus the fee shown above. Renew every year before your decal expires.
