2020 NARW Speed Restriction - Updates

Due to the increased presence of North Atlantic Right Whales (NARWs) in the Gulf of St. Lawrence, seasonal speed restrictions apply from April 28 to November 15, 2020 through a combination of a static speed zones and five dynamic shipping corridors.

Latest information on the speed limits applicable in the dynamic zones can be found below (*)

A. Mandatory Static Zones: 

Two static zones are established, to the north and to the south of the Dynamic Shipping Zones. Vessels are instructed to proceed at a speed not exceeding 10kts over the ground in these two static zones.  Mariners are however encouraged to take into consideration the potential for their vessel striking NARWs when considering a "safe operational speed" during navigation.

New for 2020: Two Seasonal Management Areas where the static speed restriction will apply only between April 28 to June 30, in recognition of NARW distribution in past season (see SMA-1 and SMA-2 in map below). 

B. Mandatory Dynamic Shipping Zones:

Vessels may proceed at a safe operational speed when the Government of Canada has completed aerial surveillance over the dynamic shipping zones and determined that no whales are present in these areas.  Information on applicable speed limits is continuously broadcasted to vessels by the CCG MCTS via Navigation warnings (NAVWARNs, formely known as NOTSHIPs).  

As per the latest NAVWARN NW-Q-0842-20 (effective 2100 UTC, June 30, 2020):

    Sector A: Vessels to proceed at speed not exceeding 10 knots as a NARW sighted on June 30

    Sector B: Vessels may proceed at a safe operational speed

    Sector C: Vessels may proceed at a safe operational speed

    Sector D: Vessels may proceed at a safe operational speed

    Sector E: Vessels may proceed at a safe operational speed

C. Trail Voluntary Speed Restriction in Cabot Strait (new for 2020 - shaded grey area below)
Between April 28 to June 15:  Vessels are asked to voluntary reduce speed to 10.0 knots, in order to minimize the risk of vessel collision, as NARWs are migrating into the Gulf through this corridor - click HERE for NW-M-0585-20.
