Mufflers and Noise Level Limits
All vessels propelled by internal combustion engines must be equipped with an effective muffling device. Vessel operators may not hear sound signals or voices if the engine is not adequately muffled.
- It is illegal to remove the muffler or render it inoperative.
- You may not modify a muffler or muffling system if the result is increased noise level.
- Vessels participating in regattas, races, or similar events being held with permission from the mayor are exempt from these requirements.
