- Boaters seeking moorage on two Seattle-area lakes
- Worth noticing
- The page says its directory draws from public sources and clarifies that listed marinas are not affiliated unless they say so.
Field notes
The signup form collects a preferred lake and optionally a boat length, plus a mobile number for text alerts. Harbor Base describes a separate operator side with a live dock map, waitlists, agreements, billing, and paperwork; these are presented as product features, while the page itself offers early access rather than an app to use now. Its map preview names 30 places, while the broader search copy says 46.
