278 slips on Lake Union ranging from 12-200', offering both covered and uncovered options with power up to 100A. Some offer pump-out and other amenities.
Marinas typically need to separate slip holder parking from day-visitor parking, trailer areas, launch ramps, and secure dock access points. Modern facilities use barrier gate systems to enforce these zones automatically — allowing permitted vehicles through via transponder or keycard while logging all access events.
