Speed Regulations

Failure to regulate speed is defined as operating a boat or PWC at speeds that may cause danger, injury, damage, or unnecessary inconvenience. In South Carolina, speed regulations can vary depending on local conditions. Be aware of and obey all regulatory markers, including those marked as “idle speed” or “no wake, idle speed.”
- You may not operate a boat or PWC in excess of “idle speed” within 50 feet of:
- A moored or anchored vessel
- A wharf, pier, or dock
- A person in the water
- Operating in excess of “idle speed” within 100 yards of the Atlantic coastline is prohibited.
- You may not operate too fast for the conditions on the water (vessel traffic, weather, etc.).
- You must maintain “idle speed” when in the vicinity of a boat flashing a blue light.
- Vessel operators are responsible for any damage caused by their wake.
