Keep an eye out for us on Lake Washington during the Seattle Seafair Weekend Festival!
July 30th – Aug. 2nd we’ll be on-scene to ensure safety on the water in two distinct regulatory areas.
Regulated Navigation Area (RNA): Active daily from 8 a.m. to 6 p.m., July 30-Aug. 2, all vessels in this designated portion of Lake Washington must operate at a slow, minimum wake speed of 7 mph or less. A slightly higher speed is permitted if necessary to maintain steerage.
Safety Zone: Active from 10 a.m. to 4 p.m. July 30 to Aug. 2, this zone encompasses the waters of Lake Washington west of Mercer Island between the Interstate 90 bridge and the easternmost point of Bailey Peninsula, including Andrews Bay. Except for official support vessels, crafts registered with the event organizers, or other vessels authorized by the Captain of the Port, no unauthorized vessels may enter or remain in the safety zone without permission from the Coast Guard.
Mariners can request authorization via VHF-FM Channel 16.
If you’re heading out onto the water this weekend, remember:
Wear a lifejacket
Don’t drink and drive - Yes, boats count!
VHF-FM marine radio
Don’t overload your vessel
File a float plan
Prepare for water exposure and the potential for cold water shock or hypothermia – the water’s cold!
