How old do you have to be in SC to operate a boat? Here’s what the law says
Whether you’re heading out from sunny Beaufort or the shores of Hilton Head, there are a handful of safety tips to keep in mind before getting on the water, no matter if you’re a seasoned pro or just learning your way around the docks.
As boats begin to fill local waterways for the Fourth of July holiday, it’s a critical time to review South Carolina’s boating laws to stay smart on the water and enjoy the remainder of the warm summer months
Here’s everything to know about boater safety, operation age limits and penalties for boating under the influence as patrols and safety checks are planned across the state this holiday weekend.
Boater Education and Age Requirements
South Carolina law now requires boaters born on or after July 1, 2007, to complete a state-approved boater education course and carry their boating safety certificate if operating a vessel with a motor of 10 horsepower or more.
Exemptions to this course include those born before July 1, 2007, holders of Coast Guard or merchant mariner credentials, nonresidents with equivalent credentials or those accompanied by a certified adult.
Here’s how the law breaks down in terms of horsepower restriction, safety requirements and supervision:
No driver’s license is required to operate a boat in South Carolina.
Adults 16 and older can operate any boat without restrictions, provided they meet the state’s boating regulations.
For those under 16, if the vessel has 15 horsepower or more, they must have a boater education card or be supervised by someone 18 years or older who meets the state’s boating regulations.
Boater safety courses can be completed in person through the South Carolina Department of Natural Resources or online via providers like Boat-Ed and BoatUS Foundation.
The SCDNR accepts any course approved by the National Association of State Boating Law Administrators.
Even if you were born before 2007, these courses are helpful for boaters of all ages to learn the rules of the water.
Know the Local Boating Rules
While the waters in Beaufort County are not treacherous, they can be tricky to navigate due to the tides.
Tides in Beaufort County can rise or fall by 8.5 feet every 6 hours. Shifting water levels, sandbars, submerged hazards and changing weather conditions are important to pay attention to so you can avoid running aground or getting stranded.
During low tide, it’s easier to see the sandbars, whereas at high tide it’s not, so ensure to follow any signs posted and stay in areas you are familiar with.
The SCDNR and Coast Guard have signs posted for restricted areas and no-wake zones. If you see a sign for a no-wake zone, make sure to slow down your speed so you don’t cast a wake.
Make sure to also stay aware of the weather conditions, including any hazards or storm warnings.
Boating Under the Influence (BUI)
Boating under the influence of alcohol or drugs is both dangerous and illegal, with almost half of boating accidents involving alcohol.
Driving a boat is just like driving a car, except on the water, lending South Carolina’s BUI laws mirroring DUI laws for vehicles.
All motorized watercraft and outboards 5 hp or greater must be titled and registered in South Carolina. Annual registration costs $20. Details and applications are available here.
It is unlawful to operate any boat or personal watercraft while under the influence of alcohol or drugs to the point that your faculties are “materially and appreciably impaired.”
Penalties can include:
1st offense: Fine up to $200 or jail up to 30 days
2nd offense: Fine between $2,000 and $5,000 and/or up to 1 year in jail
3rd offense: Fine between $3,500 and $6,000 and jail time of up to 3 years
In addition, BUI convictions result in a mandatory boating suspension for up to two years for repeat offenses.
To report reckless or intoxicated boaters, you can contact the SCDNR 24-hour hotline at 1-800-922-5431 or dial #DNR on your mobile phone.
Safety Checks and Required Equipment
The SCDNR will be out in full force over the Fourth of July holiday weekend, conducting courtesy safety checks on boaters to keep those out on the water safe and informed.
SCDNR Safety Inspection Locations in Beaufort County include:
Battery Creek Boat Landing on Friday, July 4, from 9 to 11 a.m.
Lemon Island Boat Ramp on Sunday, July 6, from 9 to 11 a.m.
Other than these courtesy checks, SCDNR officers will be out on the waters.
DNR officers are legally allowed to stop vessels to ensure compliance with safety and registration regulations. Make sure to stop for all patrol vessels with blue flashing lights.
Per law, all boats must carry:
One life jacket (personal flotation device) per person on board
One Type IV throwable flotation device
Visual distress signals, like an air horn or whistle
A Coast Guard-approved fire extinguisher
Up-to-date boat registration and title (motorized vessels and outboards 5 hp+)
These inspections are non-punitive, meaning you won’t be ticketed during the check if you’re missing an item, but you’ll be advised to correct it before launching.
Safety Tips
All riders must wear a life jacket (PFD)
Keep hands, feet and clothing inside the vessel
Never exceed the manufacturer’s capacity or your own skill level
Inspect electrical components regularly to prevent issues
Avoid sharp turns at high speeds, and steer clear of other boaters and docks
Take your boater safety course if required
Have all required safety gear onboard
Register and title your vessel properly
Assign a sober driver
Respect patrols and no-wake zones
