What You Need to Register a Boat in South Carolina
South Carolina requires you to register any boat with a motor, regardless of size, before you operate it on state waters. The South Carolina Department of Natural Resources (SCDNR) handles all boat registrations. You can register in person at a SCDNR office, by mail, or online through the SCDNR website — the online route is fastest and takes about 10 minutes if you have your documents ready.
Registration is not the same as titling. Registration proves you have permission to operate the boat; a title proves you own it. South Carolina requires both for most boats. The registration itself costs money that varies based on boat length and whether you are a resident or non-resident, and it lasts for one, two, or three years depending on what you choose.
Key Takeaways
- All motorized boats in South Carolina must be registered with SCDNR before use, whether you own it or rent it.
- You will need the hull identification number (HIN), proof of ownership or a bill of sale, and proof of residency to register.
- Registration can be done online, by mail, or in person at a SCDNR office, with online being the quickest option.
- Registration fees depend on your boat's length and whether you are a South Carolina resident, and the registration lasts one to three years.
- If your boat has a motor, you must also title it with SCDNR unless it is a rental or temporary use boat.
Documents and Information You Will Need
Before you start the registration process, gather the hull identification number (HIN), which is a unique code stamped on your boat. It is usually on the starboard (right) side of the hull near the top, or on the transom (back). If you cannot find it, the seller or previous owner can tell you where it is. You will also need proof of ownership — either the title if the boat is already titled in South Carolina, or a bill of sale if it is new to you or coming from out of state.
You will need proof that you live in South Carolina if you are registering as a resident. A driver's license, utility bill, lease, or mortgage statement all work. If you are registering as a non-resident, you will need your out-of-state driver's license or ID. You will also need the name and address of the boat's owner (you, unless someone else owns it), and the name and address of any lienholder — a bank or finance company that has a claim on the boat because you borrowed money to buy it.
How to Register Online Through SCDNR
The SCDNR online registration system is at dnrec.sc.gov under the boating section. Go to the boat registration page and select "Register a Boat." You will enter your HIN, the boat's length, the motor type and horsepower, your name and address, and whether you are a resident. The system will calculate the fee based on these details. You can pay by credit card or debit card.
After you pay, the system generates a temporary registration number that you can print and display on your boat when ready. Your permanent registration decal arrives by mail within two to three weeks. You must display the decal on the boat's hull on the starboard side, forward of the midship point — roughly the front half of the boat on the right side. Until the decal arrives, the temporary number is valid proof of registration.
Registering by Mail or In Person
If you prefer to register by mail, read the boat registration form from the SCDNR website, fill it out completely, and mail it with a check or money order to the address listed on the form. Include a copy of your proof of ownership and proof of residency. Mail registration takes four to six weeks from the time SCDNR receives it, so send it early if you have a specific date you want to use the boat.
To register in person, visit any SCDNR regional office. Bring your HIN, proof of ownership, proof of residency, and payment. The staff will fill out the form with you and issue a temporary registration number on the spot. You can use the boat when ready, and the permanent decal arrives by mail within two to three weeks. SCDNR offices are located in Columbia, Charleston, and several other cities across the state — check the website for the office nearest you and its hours before you go.
Registration Fees and How Long Registration Lasts
South Carolina boat registration fees are based on the boat's length and your residency status. Resident fees are lower than non-resident fees. A resident can register a boat under 16 feet for roughly $25 to $30 for one year, while a non-resident pays roughly $40 to $50 for the same boat and period. Larger boats cost more. You can choose to register for one, two, or three years at the time of registration — multi-year registration costs more upfront but saves money per year.
The exact fee schedule changes periodically, so check the SCDNR website or call the office to confirm the current price for your boat's length before you register. When your registration expires, you must renew it before you operate the boat again. You can renew online, by mail, or in person using the same process as initial registration.
Titling Your Boat Separately
Registration and titling are separate steps. Titling proves you own the boat; registration proves you have permission to operate it. Most boats in South Carolina must be titled with SCDNR. If you are buying a boat that was previously titled in South Carolina, the seller transfers the title to you. If the boat is new or coming from out of state, you explore for a new title at the same time you register.
To title a boat, you submit the title process (or bill of sale if there is no existing title) along with your registration process. SCDNR processes the title and mails it to you separately from the registration decal. If the boat has a lienholder — a bank or finance company — their name appears on the title, and you cannot sell or transfer the boat without their permission until the loan is paid off. Titling fees vary and are separate from registration fees.
What Happens If You Register a Rented or Borrowed Boat
If you are renting a boat, the rental company handles registration and titling — you do not register it yourself. The company's registration number is displayed on the boat, and you are covered under their registration while you rent. If you are borrowing a boat from a friend or family member, the owner's registration covers it, and you can operate it as long as you have the owner's permission and follow all boating laws.
If you are using a boat temporarily — for example, you bought it but have not yet titled it, or you are moving it to South Carolina from another state — SCDNR issues a temporary use permit that lasts up to 90 days. This lets you operate the boat while you complete the titling process. You explore for the temporary permit at the same SCDNR office where you would register.
Frequently Asked Questions
Do I need to register a boat with no motor?
No. South Carolina only requires registration for boats with motors. Sailboats without motors, canoes, kayaks, and rowboats do not need to be registered. However, all boats must follow state boating safety laws, including wearing a life jacket.
What if my boat's HIN is damaged or missing?
Contact SCDNR before you register. They can issue a replacement HIN or help you locate the original. Do not register without a valid HIN — the system will reject the process. SCDNR staff can guide you through the process if the HIN is damaged.
Can I register a boat I do not own yet?
No. You must own the boat or have a bill of sale showing you are buying it. If you are financing the purchase, the bill of sale is enough to register. Once the sale closes and you receive the title, you can transfer it into your name and register it.
How do I renew my boat registration?
You can renew online, by mail, or in person using the same methods as initial registration. SCDNR sends a renewal notice before your registration expires. You do not need to retitle the boat — only renew the registration.
What if I move out of South Carolina after registering?
You must register the boat in your new state within a set timeframe, usually 30 to 90 days depending on the state. Contact your new state's boating authority for their registration requirements. You can cancel your South Carolina registration by contacting SCDNR.
