South Carolina boat registration is handled by the Department of Natural Resources (SCDNR), not your county clerk

If you own a boat in South Carolina, you register it through the SCDNR's Boat Registration Section, not through your vehicle registration office. The process differs from car registration because boats are regulated under state boating laws rather than motor vehicle codes. You can register online, by mail, or in person at an SCDNR office.

Registration is required for any motorized vessel — including boats with outboard motors, jet skis, and sailboats with auxiliary motors — if it operates on South Carolina's public waters. Non-motorized boats like canoes and rowboats do not need registration. The registration serves as proof of ownership and is valid for three years from the date of issue.

Key Takeaways

  • South Carolina requires registration for any motorized boat, and the SCDNR issues the certificate directly — not your county clerk's office.
  • You need proof of ownership (bill of sale, manufacturer's certificate, or previous registration), the boat's hull identification number, and the owner's driver's license or ID.
  • Registration costs vary by boat length and motor type, and the certificate is valid for three years.
  • You can register online through the SCDNR website, by mail, or at any SCDNR regional office or authorized agent location.

Documents you need to register a boat

Before you contact SCDNR, gather your proof of ownership. If the boat is new, you will have a Manufacturer's Certificate of Origin (MCO). If you bought it used, you need a bill of sale signed by the previous owner. If the boat was already registered in South Carolina, bring the previous registration certificate.

You will also need the boat's hull identification number (HIN), which is permanently stamped on the hull, usually on the starboard (right) side near the stern. Write down the 12-character number exactly as it appears. Bring a valid photo ID — your driver's license works — and the owner's Social Security number or federal tax ID if the boat is owned by a business.

If someone other than the owner is registering the boat, bring a notarized power of attorney or a letter from the owner authorizing the transaction. SCDNR staff can tell you whether your specific ownership document is acceptable before you submit it.

Registration fees and how long the certificate lasts

SCDNR charges registration fees based on the boat's length and motor type. Boats under 16 feet cost less than boats 16 to 26 feet, which cost less than boats over 26 feet. Sailboats with auxiliary motors are charged differently than powerboats. The SCDNR website lists the current fee schedule by category — fees change periodically, so check the official rate table rather than relying on a quoted amount.

Your registration certificate is valid for three years from the issue date. You do not renew it annually like a car registration. When the three years expire, you renew the entire registration with SCDNR, not through a county office. You will receive a renewal notice by mail before expiration if your address is current.

How to register online, by mail, or in person

Online registration is the fastest route. Visit the SCDNR website, navigate to the Boat Registration Section, and use their online portal. You will upload images of your proof of ownership and HIN, enter the boat and owner information, and pay the fee by credit card. Processing typically takes five to seven business days, and SCDNR will mail the certificate to your address.

Mail registration requires you to print the process form from the SCDNR website, include copies of your proof of ownership and a photo ID, write a check or money order for the registration fee, and mail everything to the SCDNR Boat Registration Section address listed on the form. Mail processing takes two to three weeks from receipt. Include a phone number so SCDNR can contact you if documents are missing or unclear.

In-person registration is available at SCDNR regional offices and at authorized agents in some counties — typically bait and tackle shops or marine dealers. Bring originals of all documents, your payment method, and the HIN. Staff can process your process on the spot and issue a temporary registration receipt while your permanent certificate is mailed. This route is fastest if you need proof of registration when ready.

What happens if your boat information changes

If you sell the boat, the new owner must register it in their name. The previous registration does not transfer. Provide the buyer with a bill of sale and any documents that came with your registration packet. The new owner then follows the standard registration process with SCDNR.

If you change your address, move to a different county, or change the boat's name or motor, contact SCDNR to update your registration. Some changes require a new certificate; others are noted on your existing one. The SCDNR website explains which changes require a new process and which are updates only.

Where to find SCDNR boat registration offices and contact information

The main SCDNR Boat Registration Section is located in Columbia. You can reach them by phone during business hours to ask questions about your specific boat or documents before you submit an process. The SCDNR website lists all regional office locations, hours, and phone numbers. Many counties also have authorized agents — marine dealers, bait shops, or sporting goods stores — that can accept applications in person.

If you are unsure whether your boat needs registration or whether your documents are acceptable, call SCDNR before you gather everything. Staff can confirm your boat type, tell you the exact fee, and let you know if your proof of ownership will work. This saves a trip or a mailed process that comes back incomplete.

Frequently Asked Questions

Do I need to register a sailboat with no motor?

No. South Carolina requires registration only for motorized vessels. A sailboat with no auxiliary motor does not need to be registered with SCDNR. If you add a motor later, you must register it before operating the motor on public water.

What if I bought my boat out of state and it was registered there?

You must register it with SCDNR within 30 days of bringing it to South Carolina. Bring the out-of-state registration certificate as proof of ownership along with your other documents. SCDNR will issue a South Carolina certificate, and you can use the out-of-state one until yours arrives.

Can I register a boat if I do not have a bill of sale?

A bill of sale is the standard proof of ownership for used boats. If you do not have one, contact SCDNR to ask what documents they will accept instead — a previous registration, a manufacturer's certificate, or a notarized statement of ownership may work depending on your situation. Call before you explore so you know whether your documents are acceptable.

How do I renew my boat registration after three years?

SCDNR will mail you a renewal notice before your certificate expires. You can renew online, by mail, or in person using the same methods as initial registration. You do not need to provide proof of ownership again — just your current certificate, the renewal form, and payment.

What if I lose my registration certificate?

Contact SCDNR and request a duplicate. You will need to provide your boat's HIN and proof of ownership. SCDNR can issue a replacement certificate by mail or, at some locations, in person. There is usually a small fee for a duplicate.
