The At Lake Union Park Working Group consists of many of the Partner Organizations that use Lake Union Park, or just Lake Union, as their hub.

Many of the participants are non-profit organizations who want to continue to provide access to and educate people about one of Seattle's gems, Lake Union.

The Lady Washington and Hawaiian Chieftain, both home-ported in Grays Harbor and owned by the Aberdeen-based Grays Harbor Historical Seaport Authority, provide educational, vocational, recreational, and ambassadorial activities and experiences that promote and preserve the maritime history of Grays Harbor, the Pacific Northwest, and our nation while serving the needs of the community.

The Lady Washington is the Official Ship of the State of Washington. The Hawaiian Chieftain accompanies her on her voyages and goodwill missions. Both ships welcome the public during visits to ports in Washington, Oregon, California, British Columbia, and at Lake Union Park!
