Access, Safety and Regulations
Access
Use public harbor access, town landings, and lawful wade areas. Respect private docks and marked restricted zones.
Primary hazards
Strong entrance exchange, boat traffic, and changing flats depths are primary hazards. Open-sound seas are not the wave height inside the harbor.
Regulations
Size limits, seasons, and possession rules change. Verify the current official regulations before fishing.
