This is a pilot project funded by the city of Alameda, the San Francisco Bay Ferry, the Port of Oakland, and a transportation nonprofit (Alameda Transportation Management Association). They claim it was inspired by water transportation in Amsterdam, although I'm thinking across an estuary like this isn't quite the same.
They're using an old boat that used to do tours in Buffalo, NY. Never knew that was a thing. The service is free, connecting between Jack London Square in Oakland and a city park in Alameda. I've taken San Francisco Bay Ferry between Oakland and Alameda as a longer trip to/from San Francisco, but the Alameda location is further away and kind of in the middle of nowhere. At least the Alameda location for the water taxi is a fairly close walk to a Target and other shopping. Still - I've gone there before, and I'm thinking anyone with a car would probably just drive there from Oakland through the Webster Tube. The distance of the water taxi route looks to be about 600 feet across the Oakland Estuary.

- Be ADA-accessible
- Accommodate bicycles easily
- Run between Alameda Landing (behind Target, at the Bohol Circle Immigrant Park dock) and Oakland's Jack London Square (at the foot of Broadway)
- Operate 5 days per week, Wednesdays through Sundays. Service levels may change later depending on funding and season.
- Be a two-year pilot, with the opportunity to grow over time
