                              Get ready to hear the nostalgic sounds of hydroplanes!

Seattle Outboard Association is hosting the 10th annual Kenmore Hydroplane Cup Event. The 2- and 3-cylinder outboards will leave the public Kenmore Boat Launch for a timed exhibition race around a buoy at the entrance to the slough upriver past the boat launch, and ƛ̕ax̌ʷadis (Tl' awh-ah-dees) Park, around the bend to the right and around another buoy at the Kenmore City Limits, and back to the Kenmore Boat Launch. Only one boat at a time will be on the river.

Vintage Inboards will be on display starting at 10am at the Kenmore Boat Launch along with meet & greet opportunities with the drivers, aged youth to adult.

Bring your cameras, and take your picture in one of their boats!

The opening ceremonies will start at 10 am. Races start at 12 noon and running until about 4 pm.

The best viewing areas will be the 68^th Ave bridge walkway and from ƛ̕ax̌ʷadis (Tl' awh-ah-dees) Park.

This historic event has brought the community to the banks of the Sammamish Slough since 1938 and ended in 1976.  The idea to reintroduce the event 11 years ago came after local artist, Amberly “Gaul” Culley organized the Sammamish Slough race exhibit at Kenmore City Hall in 2013.  Amberly and Jan Shaw restarted the event that year with great community support and has continued moving father up the river each year.

This will be an exciting event so please grab your friends and family and come on down to watch history once more in the making!
