North Atlantic right whale vessel speed restrictions reduce the likelihood of lethal collisions between vessels and these endangered whales.
In 2013, NOAA Fisheries committed to publish a report evaluating the conservation value and economic and navigational safety impacts of the 2008 North Atlantic right whale vessel speed regulations (50 CFR § 224.105). The report was finalized in June 2020 and evaluates four aspects of the right whale vessel speed rule: biological efficacy, mariner compliance, impacts to navigational safety, and economic cost to mariners. It also provides a detailed assessment of the rule’s effectiveness, and assesses general trends in vessel traffic characteristics within Seasonal Management Areas over time.
NOAA Fisheries solicited public comment on the speed rule assessment. The comment period closed at the end of March 2021 and we are posting comments received for public reference.
All vessels 65 feet (19.8 meters) or longer must travel at 10 knots or less in certain locations (called Seasonal Management Areas or SMAs) along the U.S. east coast at certain times of the year to reduce the threat of vessel collisions with endangered North Atlantic right whales. The purpose of this mandatory regulation is to reduce the likelihood of deaths and serious injuries to these endangered whales that result from collisions with vessel.Because vessels of all sizes can strike a whale, NOAA Fisheries also encourages vessels less than 65 feet in length to help protect right whales by slowing to 10 knots of less within active SMAs as well.

Right Whale Slow Zones is a program that notifies vessel operators of areas where maintaining speeds of 10 knots or less can help protect right whales from vessel collisions. Under this program, NOAA Fisheries provides maps and coordinates to vessel operators indicating areas where right whales have been detected. Mariners are encouraged to avoid these areas or reduce speeds to 10 knots or less while transiting through these areas for 15 days.
Right Whale Slow Zones are established around areas where right whales have been recently seen or heard; these areas are identical to Dynamic Management Areas (DMA) when triggered by right whale visual sightings but, they will also be established when right whale detections are confirmed from acoustic receivers.
NOAA Fisheries announces Right Whale Slow Zones to mariners through its customary maritime communication media and displays any active zones below, with the most recent designation first.
All boaters from Maine to Virginia, or interested parties, can sign up for email or text notifications about the latest Right Whale Slow Zones. You can also follow us on Facebook (@NOAAFisheriesNEMA) and Twitter (@NOAAFish_GARFO) for announcements.
You can check for Right Whale Slow Zones on our online right whale sightings map. Or, you can download the free Whale Alert app, which will automatically notify you when you enter one of these areas.
Voluntary Dynamic Management Areas (DMAs) may be established by NOAA Fisheries based on visual sightings documenting the presence of three or more right whales within a discrete area. Mariners are encouraged to avoid these areas or reduce speeds to 10 knots or less while transiting through these areas. DMAs are announced to mariners through its customary maritime communication media and display any active ones, with the most recent designation first.
For ships weighing 300 gross tons or more, a voluntary seasonal Area To Be Avoided (ATBA) is in effect each year from April 1 to July 31, when right whales face their highest risk of ship strikes in this area.
The North-South lanes of the Traffic Separation Scheme servicing Boston were narrowed from 2 miles to 1.5 miles (consistent with the East-West Boston Traffic Separation Scheme lanes) to reduce vessel collisions with whales.
NOAA established recommended vessel routes in four locations to reduce the likelihood of ship collisions in key right whale habitats in Massachusetts, Georgia, and Florida.
When ships greater than 300 gross tons enter two key right whale habitats—one off the northeast U.S. and one off the southeast U.S.—they are required to report to a shore-based station.
In return, ships receive a message about right whales, their vulnerability to ship strikes, precautionary measures the ship can take to avoid hitting a whale, and locations of recent sightings.
Mandatory Ship Reporting System areas will soon be available on all NOAA Electronic Navigation Chart products.
