Delaware Vessel Registration: How to Legally Enjoy Boating in the First State

Whether you’re planning a lazy afternoon on the Delaware Bay, a fishing trip on the Nanticoke River, or a fast ride on the Rehoboth Canal, one thing is certain—your boat (or personal watercraft) needs to be properly registered before it hits Delaware’s public waters. Delaware makes the registration process pretty straightforward, but missing a step can turn a fun day into a hassle. Here’s your complete, easy-to-follow guide to registering a vessel in Delaware, including who needs to register, what documents you’ll need, fees, renewals, and a few tips to keep things smooth and legal.

Who Needs to Register a Vessel in Delaware?

Delaware law, overseen by the Department of Natural Resources and Environmental Control (DNREC), says you must register:

Any motorized boat, regardless of length, used on Delaware public waters.
Any sailboat 12 feet or longer.
Personal watercraft (PWCs) like Jet Skis, Sea-Doos, and WaveRunners.
Boats documented with the U.S. Coast Guard, if primarily used in Delaware (they must obtain a state decal).

Exemptions: Canoes, kayaks, and other non-motorized vessels under 12 feet, lifeboats used only in emergencies, boats registered in another state using Delaware waters for less than 60 consecutive days, and boats used solely on private property.

How to Register Your Vessel in Delaware

Gather Required Documents:
- Proof of ownership: bill of sale, manufacturer’s certificate of origin (for new boats), out-of-state title or registration, or Coast Guard documentation.
- Hull Identification Number (HIN), required for all boats built after 1972.
- Completed application for vessel registration (available from DNREC’s website or in person).
- Payment for registration fees (see below).
Submit Your Application:
- Register in person at a DNREC office or at some authorized boat dealers. You can also renew online or by mail.
Receive Your Registration and Decals:
- You’ll get a Certificate of Number and two decals. Keep the certificate on board and display the decals on both sides of the boat’s bow.

Where and How to Display Your Numbers and Decals

Delaware registration number (DE followed by numbers and letters) must be painted or attached to each side of the forward half of the vessel, in block letters at least three inches high, contrasting with the hull color.
Decals are placed within six inches after (toward the stern) the registration number.

Renewals, Transfers, and Changes

Renewals: Can be done online, by mail, or in person before expiration. Late renewals may result in penalties.
Transfers: Must be completed within 15 days of buying or selling a boat. The new owner submits a new application, bill of sale, and pays the fee.
Change of Address: Notify DNREC within 15 days of moving.
Lost Certificate or Decals: Request replacements from DNREC for a small fee.

Special Cases and Exemptions

Coast Guard Documented Vessels: Must obtain a Delaware decal to operate in state waters.
Homemade Boats: Must be inspected and assigned a HIN before registration.
Boats Used Solely on Private Lakes: Exempt from state registration.

Boater Safety Requirements

Anyone born after January 1, 1978 must complete a DNREC-approved boating safety course to operate a motorized vessel. Carry your safety certificate and registration onboard at all times.

Penalties for Not Registering Your Vessel

Using an unregistered or expired vessel can result in fines, citations, or having your boat removed from the water. You also risk losing proof of ownership if the vessel is stolen or in an accident.

Tips for Smooth Registration

Check your paperwork for accuracy before submitting—incorrect HINs or missing bills of sale cause delays.
Renew before the busy summer boating season to avoid last-minute rushes or fines.
Keep your registration and safety certificate on board at all times.
For special cases (homemade boats, missing HINs), call DNREC for help before applying.
