Recommendation: 17

Status: Complete

Establish a statewide, “go-slow” bubble for small vessels and commercial whale-watching vessels within half a nautical mile of Southern Resident orcas.


Action 1

Enact legislation to create a half-mile, “go-slow” zone around Southern Resident orcas. Vessels within the zone should not exceed 7 knots.

Action 2

Coordinate and align regulations among state, federal, and Canadian authorities and provide enforcement, public outreach, and education as needed.

Implementation Details

In the 2019 legislative session, the Washington State Legislature and Governor should update Revised Code of Washington 77.15.740 to establish a statewide, “go slow” bubble for small vessels operating within a half nautical mile of Southern Resident orcas. “Go slow” is defined as a 7 knot speed over ground, as measured using a Global Positioning System. It is intended that law enforcement officers will use discretion when enforcing this section and granting exceptions for safety, and will provide public outreach and education when appropriate.

Recent Progress

  • The Washington Department of Fish and Wildlife submitted its Southern Resident Killer Whale Vessel Adaptive Management 2022 report to the Legislature. It’s required to report on new vessel regulations every 2 years.
  • Senate Bill 5371 and House Bill 1145 are being considered by the Legislature.
  • In 2019, the Legislature revised Revised Code of Washington 77.15.740 to prohibit vessels from exceeding a speed of 7 knots within a half nautical mile of Southern Resident orcas.
  • The Washington State Parks and Recreation Commission received a one-time payment of $150,000 to train staff and local governments and add regulation information about Southern Resident orcas to its boater education curriculum and testing. Most recreational boaters must pass a test to receive their boater safety card.
