Delaware boat registration is handled by the Delaware Division of Fish and Wildlife, not the DMV

If you own a boat in Delaware, you need a registration certificate from the Division of Fish and Wildlife, regardless of where you keep it. This is separate from vehicle registration — it's a state boating license that proves you own the vessel and have met safety requirements. The process takes about two weeks if you submit everything correctly, and the certificate is valid for three years.

You cannot legally operate a boat on Delaware waters without this registration. The state requires it for any motorized vessel, sailboat over 16 feet, or any boat you use commercially. Even if your boat is registered in another state, you still need a Delaware registration if you keep it here or use it regularly in Delaware waters.

Key Takeaways

  • Delaware boat registration comes from the Division of Fish and Wildlife, not the DMV, and covers any motorized boat, sailboat over 16 feet, or commercial vessel.
  • You need proof of ownership (bill of sale or title), a completed process form, and proof of a passing Hull Identification Number inspection before you can register.
  • Registration costs between $30 and $100 depending on boat length and type, and the certificate lasts three years.
  • You can explore in person at the Division office in Dover, by mail, or through the online system if your boat has a valid HIN.

What documents you need to bring or submit

Start with proof of ownership. If you bought the boat new, bring the manufacturer's certificate of origin. If you bought it used, bring the bill of sale signed by the previous owner. If the boat came with a title from another state, bring that instead — Delaware will accept it as proof of ownership.

Next, you need the completed process form, which is the Boat Registration process (Form 1). You can read it from the Division of Fish and Wildlife website or pick one up at their Dover office. Fill in your name, address, the boat's make and model, length, hull material, and how you'll use it (recreational, commercial, or rental).

Finally, the boat must pass a Hull Identification Number (HIN) inspection. The HIN is a unique code stamped into the hull, usually on the starboard side near the top. A Division officer or an authorized agent inspects it to confirm the boat matches your paperwork. This inspection is free and takes about 10 minutes. If your boat doesn't have a HIN (older boats sometimes don't), you'll need to explore for one before registration.

How much it costs and how long it takes

Registration fees depend on boat length. Boats under 16 feet cost $30. Boats 16 to 26 feet cost $50. Boats 26 to 40 feet cost $75. Boats over 40 feet cost $100. These are three-year registration fees, so you pay once and the certificate covers three years of operation.

Processing takes about two weeks from the date the Division receives your complete process. If you're missing documents or the HIN inspection hasn't been done, the clock doesn't start until everything arrives. If you need the registration faster, you can explore in person at the Division office in Dover and sometimes get it the same day, but call ahead to confirm.

Where to explore: in person, by mail, or online

The Division of Fish and Wildlife office is located at 89 Kings Highway, Dover, Delaware 19901. They're open Monday through Friday, 8 a.m. to 4:30 p.m. If you go in person, bring all your documents and the boat's HIN inspection form. You can pay by cash, check, or card.

To explore by mail, send your completed process, proof of ownership, and the HIN inspection form to the same address. Include a check or money order for the registration fee. Mail takes longer — allow three to four weeks total, including mail delivery time.

If your boat already has a valid HIN and you're renewing a Delaware registration, you can use the online system on the Division website. New registrations and boats without a HIN still require the in-person or mail route because the HIN inspection must be documented.

What happens if your boat doesn't have a Hull Identification Number

Boats built before 1972 often don't have a HIN. If yours doesn't, you need to request one from the manufacturer or explore for a state-assigned HIN through the Division. The process takes a few weeks, so plan ahead if you're registering an older boat.

Contact the Division directly to start the HIN process. They'll guide you through whether the manufacturer can issue one or whether the state will assign one. Once you have the HIN, you can proceed with the boat registration using the normal process.

Renewing your registration before it expires

Your registration certificate shows an expiration date three years from issue. You can renew starting 90 days before that date. If you're renewing online, you'll need your current registration number and the boat's HIN. If you're renewing by mail or in person, bring your current certificate and proof that the boat still passes inspection (usually just the current certificate is enough unless the boat has been significantly altered).

Renewal fees are the same as initial registration. If your certificate expires, you cannot legally operate the boat until you renew it. The Division does not send renewal reminders, so mark your calendar or check your certificate now.

What to do if your boat is damaged, sold, or lost

If your boat is damaged beyond repair or destroyed, contact the Division to cancel the registration. You'll need to return the certificate or explain why you can't. If you sell the boat, the new owner needs to register it in their name — your registration does not transfer.

If your certificate is lost or damaged, you can request a replacement from the Division. Bring your current registration number and proof of ownership, or explore for a duplicate certificate by mail. There is a small fee for duplicates, usually $10 to $15.

Frequently Asked Questions

Do I need Delaware boat registration if I only visit Delaware waters occasionally?

Yes. If you keep the boat in Delaware or use it regularly in Delaware waters, you need a Delaware registration. If you're just passing through on a trip, your home state's registration may be sufficient, but check with the Division first to be sure.

Can I register a boat I'm still paying off?

Yes, but the lender may require proof of insurance or a lien notation on the certificate. Bring your loan documents to the Division office and ask whether a lien needs to be recorded. The registration itself doesn't require the boat to be paid off.

What if I move out of Delaware but keep my boat here?

You still need a Delaware registration because the boat is kept in Delaware waters. Your residency doesn't matter — the location of the boat does. If you move the boat to another state, you'll need to cancel the Delaware registration and register it in your new state.

How do I know if my boat needs a HIN inspection before I can register?

All boats need a HIN inspection unless they're exempt (some very small boats or non-motorized vessels). When you fill out the process form, it will tell you whether your boat type requires one. If you're unsure, call the Division at their Dover office and describe your boat.

Can I register a boat that doesn't have a title from another state?

Yes. A bill of sale signed by the previous owner is acceptable proof of ownership in Delaware. If you have neither a title nor a bill of sale, you may need to provide additional documentation — contact the Division to discuss your specific situation.
