Boaters play a crucial role in safeguarding the diverse species that inhabit the Salish Sea. As you explore and enjoy the stunning waters and shores, it’s important to minimize your wake. Whether you’re on a sailboat or powerboat, continue reading to discover how you can lessen your impact on the wildlife and communities that rely on these waters for sustenance and shelter.

Once you’re done reviewing,

Protect this place. Anchor out of Eelgrass!

Download Friends of the San Juans’ free eelgrass depth map to help guide where you anchor while cruising in the San Juans. Keep a copy on your boat for when you are offline! Printed and laminated versions are also available by emailing [email protected].

Protect this place. Give Them Space and Be Whale Wise!

Give Southern Resident killer whales more space. The critically endangered Southern Residents are impacted by vessel noise and presence. Current regulations require boaters to travel at 7 knots or less within one-half nautical mile of these whales. Boaters are also encouraged to turn off depth finders within one-half nautical mile.

New vessel distance requirements will take effect in 2025 but you can take the pledge today to voluntarily stay 1,000 yards away. Give Southern Residents the space they need to forage, feed, rest, and rear their young!

Visit BeWhaleWise.org for more info about current regulations. Learn about the Voluntary No-Go Zone for Southern Resident killer whales on the West Side of San Juan Island.

Help other people know whales are near. Watch for whale warning flags hoisted on other vessels so you can slow down or bring your boat to a stop in the presence of vulnerable marine mammals. You can get your own whale warning flag by picking up a free Green Boater Kit at our Friday Harbor office! Email us at [email protected].

Protect this place. Help keep marine animals safe.

Use the following resources to report any stranded, hurt, entangled, or endangered marine mammals. This includes sea lions, seals, whales, porpoises, and otters.

  • (800) 562-8832 marine mammal stranding network.
  • (800) 853-1964 harassments and other violations.
  • For entangled marine mammals, please call (877) 767-9425 or hail the U.S. Coast Guard on VHF Channel 16. 
  • WhaleReport Alert System – an alert system that broadcasts pertinent details of whale presence to large commercial vessels. 

Protect this place. Keep it Clean and Green!


Do your part to keep marine waters clean by using pump outs, ensuring your boat is in good working order, and quickly cleaning even small oil spills. 

  • Report Spills—It’s the law. In the event of an oil spill call 1-800-OILS-911. Even small spills need to be reported. 
  • Small Spills Aren’t Slick. Get free small spills prevention materials from SeaGrant, which includes free absorbent fuel pads, videos, tips, and more! Contrary to popular belief, Dawn Liquid Soap is not effective for small oil spills. Dawn sinks the oil to the sea floor where wildlife ingest it, and it can do more harm. Instead, place an absorbent pad over the top of the spill to soak up as much as possible—just make sure it can be retrieved!

Protect this place. Take the Pledge!
