Voluntary Vessel Speed Reduction Zone In Effect NOAA recommends that vessels > 300 gross registered tons transiting the zone do so at speeds of 10 knots or less

2018, 2019, and 2021 Were the Worst Years on Record for Whale-Ship Collisions off the West Coast of the United States.

Despite this trend, there are solutions to combat the problem. Research demonstrates ships that slow to 10 knots in areas with high whale presence significantly reduce the danger to whales.

Whale Safe is a technology-based mapping and analysis tool displaying whale and ship data—designed to prevent fatal ship collisions with whales.
