The Vancouver Fraser Port Authority is encouraging boaters to slow down when transiting the First Narrows Traffic Control Zone, which includes the area either side of the Lions Gate Bridge. The voluntary 15-knot speed restriction to help keep port users safe will be in effect between July 6 and October 1, 2018. It is applicable to all tier 2 vessels, which includes any vessel that is not a deep-sea piloted vessel. Most recreational vessels such as power boats, fishing boats, and sailboats fall into this category, in addition to tugs, ferries, and whale watching boats, among others. Deep-sea commercial vessels already follow a speed restriction of 10 knots through the First Narrows Traffic Control Zone.
