The first Saturday of May is the working start of boating season in Seattle. For over a century, the Seattle Yacht Club has hosted a boat parade through the Lake Washington Ship Canal — a miles-long procession of decorated vessels, from tiny runabouts to towering sailboats, passing beneath the Montlake Bridge in front of crowds of tens of thousands. Opening Day, every year, the same first Saturday in May.
It is not just a regatta. It is a civic event, a party, a working tradition, and an unofficial holiday for anyone who loves boats. For boats based in or visiting Seattle in late April or early May, Opening Day is the working photograph the Seattle cruising year is remembered by.
The history
The Seattle Yacht Club has hosted Opening Day since 1913, making it one of the oldest continuous boating events in the United States. The tradition began as a practical celebration: the opening of the Lake Washington Ship Canal in 1917 connected Lake Union and Lake Washington to Puget Sound, and Seattle boaters have been celebrating the spring access ever since.
Over the decades, Opening Day has grown from a small club event to a citywide festival. The decorated boat parade draws hundreds of participants. The crew race through the Montlake Cut draws college rowing teams from across the region. The galleries along the canal banks fill with spectators who may not own a boat but understand that Opening Day means summer is close.
The parade
The decorated-boat parade is the centrepiece. Boats of every size and description — powerboats, sailboats, kayaks, inflatable rafts, and floating contraptions — are decorated with flowers, flags, banners, and whatever the crews’ imagination allows. Themes range from nautical classics to pop culture to pure absurdity.
The parade route runs through the Montlake Cut, under the Montlake Bridge, and into Union Bay on Lake Washington. The bridge viewing area fills early; arrive by 0900 for a working spot. The parade typically begins around 1000 and runs for two to three hours.
Working viewing spots:
- Montlake Bridge. The prime location. Boats pass close underneath; the decorated crews are visible. Arrive very early — the bridge fills by 0830 on a sunny year.
- Portage Bay. Along the water on both shores. Slightly less crowded than the bridge.
- Stan Sayres Memorial Park. On the Lake Washington side. Good views of the arriving parade formation.
- On the water. The working best way to see Opening Day is from a boat. Join the parade or station the boat along the route as a spectator.
How to participate
Any boat can participate in the Opening Day parade. Registration is through the Seattle Yacht Club. The entry fee is modest. Decorated boats are encouraged — judges award prizes for the best themes, though the judging is friendly and the working reward is participation.
For a first-time parade boat:
- Arrive at the staging area well before the parade start (the staging area gets crowded; allow 60 minutes minimum)
- Flowers are the classic Opening Day decoration — dahlia and carnation arrangements are traditional on larger yachts
- The canal can be crowded; go slow and keep watch
- Bring more food and drinks than seems necessary; the parade takes time
Even for boats not decorated, spectator-vessel participation is workable. Follow the parade at a respectful distance and enjoy the scene.
The crew race
Running alongside the parade, the Opening Day Crew Race is a sanctioned regatta through the Montlake Cut. University of Washington, Seattle University, and other collegiate programmes race the Cut in front of the packed bridge galleries. The UW–Washington State rivalry race is traditionally held on Opening Day, drawing passionate fans.
The crew race creates a working spectacle from the bridge: long rowing shells cutting through the channel at speed while the parade boats drift past on either side.
The social scene
Opening Day is as much about gathering as racing. The SYC moorage fills with club members hosting parties on their boats. The lakefront bars and restaurants near Eastlake and Portage Bay fill to capacity by mid-morning. Neighbourhoods along the canal hold block parties.
For the non-boating public, Opening Day is the working excuse to spend a spring Saturday along the water — eating good food, watching extraordinary boats, and feeling optimistic about the summer ahead.

Closing notes
Opening Day is one of those Seattle traditions that reminds the city why living near the water is special. For one Saturday every May, the city turns its face to the water and celebrates the boats, the sailors, and the season to come. The bridge gallery, the marching college shells, the parade boats covered in dahlias, the crowds along the canal banks — it is the working photograph of Pacific Northwest boating, and it has been for over a century.
See you on the canal.
