South Carolina doesn’t have the universal boater education mandate that some neighboring states do. But that doesn’t mean there are no rules. Between age-based education requirements, equipment mandates, distance laws, and BUI penalties, there’s more to know than most boaters realize.

Who Needs a Boating Safety Course

As of August 2023, anyone born after July 1, 2007 must complete a NASBLA-approved boating safety course before operating any vessel powered by 10 horsepower or more on SC waters.

If you were born before that date, no course is required. You can operate any vessel without certification.

For operators under 16:

  • Cannot operate a vessel with 15+ HP without direct supervision by a certified adult (18+)
  • Exception: if the minor holds a Boater Education Card, they can operate unsupervised

Exemptions from the education requirement:

  • Supervised by a person 18+ who holds a boating safety certificate or USCG credential
  • Non-residents with a valid boating safety certificate from their home state
  • Holders of a U.S. Coast Guard vessel operator license
  • Holders of a rental safety certificate (valid 30 days, rental use only)

Course options:

  • Free in-person SCDNR instructor-led class (about 6 hours, one day)
  • Online NASBLA-approved courses ($10-$80 depending on provider)

Once you pass, you get a Boater Education Card. Carry it on board any time you’re operating.

Required Safety Equipment

The requirements scale with vessel size. Here’s what you need.

Personal Flotation Devices (PFDs)

  • All vessels: One USCG-approved wearable PFD (Type I, II, III, or V) for each person on board or being towed. Must be in good condition, readily accessible, and the right size for the wearer.
  • Vessels 16 feet and longer: Must also carry one Type IV throwable device (seat cushion or ring buoy).
  • Children under 12: Must WEAR a USCG-approved PFD at all times on vessels under 16 feet.
  • PWC operators and passengers: Must wear a PFD at all times. No exceptions.

Fire Extinguishers

Required if your vessel has an enclosed engine compartment, a permanently installed fuel tank, or carries passengers for hire.

Vessel LengthRequirement
Under 26 feetOne 5-B rated portable extinguisher
26 to 40 feetTwo 5-B OR one 20-B
40 to 65 feetThree 5-B OR one 20-B plus one 5-B

Note: As of 2022, the USCG requires disposable fire extinguishers to be replaced 12 years after the manufacture date stamped on the bottom. Old B-I/B-II labels are no longer accepted on vessels model year 2018 and newer.

Visual Distress Signals

Required on coastal waters only (not required on inland lakes or rivers). You must carry USCG-approved signals for both day and night use. Options include pyrotechnic flares, smoke signals, orange distress flags, or electric distress lights.

Sound-Producing Devices

  • Vessels under 65.6 feet: a whistle, horn, or other device capable of producing a loud sound
  • Vessels 65.6 feet and longer: both a whistle/horn AND a bell

Required between sunset and sunrise. Power-driven vessels under 39.4 feet need red and green sidelights (visible 1 mile) plus an all-round white light, or a masthead light and sternlight. Anchored vessels must display anchor lights.

BUI: Boating Under the Influence

South Carolina takes BUI seriously. The rules mirror DUI on the road.

BAC limit: 0.08%

Implied consent: By operating a watercraft on SC waters, you consent to chemical testing (breath, blood, or urine). Refuse the test and your boating privileges are suspended for 180 days automatically.

Penalties:

OffenseFineJailSuspension
1st$20048 hours to 30 days6 months
2nd$1,000-$5,000Up to 1 year1 year
3rd$3,500-$6,00060 days to 3 years2 years
Felony (great bodily injury)Up to $10,000Up to 15 years-
Felony (death)Up to $25,000Up to 25 years-

All offenders must complete an Alcohol and Drug Safety Action course and a boating safety course at their own expense. No part of the minimum sentence can be suspended.

Speed and Distance Rules

SC has specific idle-speed zones that vary by water body. Getting these wrong can result in fines of $25-$200 or up to 30 days in jail per violation.

Standard rule (most waters):

  • Idle speed within 50 feet of any moored or anchored vessel, wharf, dock, pier, bulkhead, or person in the water

Major lakes (Murray, Hartwell, Marion, Greenwood, Jocassee, Keowee, and others):

  • Idle speed within 100 feet of wharfs, docks, piers, or bulkheads (expanded from 50 feet in 2022)
  • Idle speed within 50 feet of moored/anchored vessels or people in the water

Atlantic coastline:

  • Idle speed within 100 yards of the coastline

Wake surfing:

  • Idle speed within 200 feet of any dock, moored vessel, anchored vessel, or person in the water

PWC wake jumping:

  • Cannot leave the water while crossing another vessel’s wake within 200 feet of that vessel

Diver-down flag:

  • Maintain at least 50-100 feet from any vessel flying a diver-down flag

Age Restrictions Summary

  • 16 and older: Operate without restrictions (assuming education requirement met if born after July 1, 2007)
  • Under 16: Cannot operate 15+ HP without adult supervision or Boater Education Card
  • PWC: Nobody under 16 can operate without an adult 18+ present
