Title Swiftsure Bank Voluntary Slowdown
Areas Juan de Fuca Strait
West Coast Vancouver Island South
Categories Waterway Information (Other)

As of June 1, 2023, the ECHO program voluntary ship slowdown in Swiftsure Bank is now in effect for all inbound and outbound commercial and government vessels to reduce the impacts of commercial shipping on at-risk whales in this key foraging area. This initiative will remain in effect 24 hours per day until 2359 PDT on October 31, 2023.      


If it is safe and operationally feasible to do so, commercial and government vessels are requested to not exceed the following speeds through the water:  


11 knots – Bulkers, tankers, general cargo vessels, and government vessels; and,  

14.5 knots – Vehicle carriers, cruise ships, and container vessels.  


The voluntary vessel slowdown takes place in the inbound and outbound lanes of the vessel traffic separation scheme between the start or end of the traffic separation scheme on the western or southern side, and the 124° 40’ W longitudinal line (traffic calling in point 1) on the eastern side.  Speed transition zones are in place about 5 nautical miles prior to entering the slowdown area.
