Transport Canada’s Ship Safety Bulletin 05/2023 provides information on speed restriction zones in the Gulf of St. Lawrence aimed at reducing vessel collisions with North Atlantic right whales (NARW). The zones include static zones, dynamic shipping zones, seasonal management areas, voluntary seasonal slowdown zone, and restricted areas. Vessels must follow Navigational Warnings (NAVWARNs) and Notices to Mariners (NOTMARs) for specific speed restrictions. Exceptions apply to vessels in distress, government vessels, and vessels engaged in specific activities. The bulletin outlines the requirements and exceptions for each zone and highlights the need for mariners to consider the risk of whale strikes when determining safe operational speeds.
