Cape May-Lewes Ferry
From Geohashing
This ferry runs from North Cape May, New Jersey to Lewes, Delaware, across Delaware Bay. If the geohash is in the bay, within about a mile of the route on the map (or a bee line between the two docks), you can qualify for both the Water Geohash and the Public Transport Geohash. If you work for the ferry, you should probably get a Cubicle Geohash, even if you don't ride the ferry across.
