About Stimson Marina
It's Seattle's largest covered and sprinklered fresh-water marina. Located on the Salmon Bay Waterway just inside the Hiram M. Chittenden Locks, we're a block away from Ballard's great shops, restaurants, and the farmers market on Sundays. We have 200 covered slips from 25 to 50 feet and over 2,000 lineal feet of open moorage. We have plenty of customer parking, showers, bathrooms, laundry, and on-site security.
