Boating off the Jersey Shore? Heads up! The Mid-Atlantic Seasonal Management Areas (SMAs) are in effect November through April

Here is what you need to know:

What is an SMA?

A Seasonal Management Area is a designated zone where vessels 65 feet or longer must follow mandatory speed limits to help protect the endangered North Atlantic right whale.

Where are the SMAs?

They cover key areas along the Mid-Atlantic coast, including waters off the Delaware Bay and the New York–New Jersey Bight.

Why do SMAs matter?

Speed restrictions reduce the risk of vessel collisions with migrating whales and help protect these critically endangered animals.

How can you help?
