Right Whale Slow Zone Extension: South of Nantucket, MA
Effective through February 2
On January 18, 2026, the Northeast Fisheries Science Center's aerial survey team redetected the presence of right whales south of Nantucket, MA. The right whale Slow Zone is in effect through February 2, 2026.
As a reminder, five additional Slow Zones are also currently in effect. Locations and effective dates are listed below.
Voluntary Right Whale “Slow Zone” Areas
Mariners are requested to avoid or transit at 10 knots or less inside the following Dynamic Management Areas and Slow Zones where endangered right whales have been detected. Vessel strikes are one of the primary causes of injury and death for right whales. Slower speeds are known to reduce the severity of impacts to whales when strikes occur and may provide boat and vessel operators an opportunity to avoid a collision.

Give Right Whales Room
North Atlantic right whales are on the move along the Atlantic coast of the United States. To protect right whales, regulations prohibit approaching or remaining within 500 yards (1,500 feet) of a right whale. That’s the length of about five football fields.
Right Whales in Trouble
Endangered North Atlantic right whales remain highly vulnerable to extinction, as human impacts continue to threaten the survival of this species. There are approximately 380 individuals remaining, including about 70 reproductively active females.
In August 2017, NOAA Fisheries declared the increase in right whale mortalities an Unusual Mortality Event, which helps the agency direct additional scientific and financial resources to investigating, understanding, and reducing the mortalities. This work is done in partnership with the Marine Mammal Stranding Network, Canada’s Department of Fisheries and Oceans, and outside experts from the scientific research community.
