DOCK-TIONARY: FLOATS AND GANGWAYS
Welcome back to Dock-tionary, where we help ferry fans learn how to speak boat. This month, we’re breaking down the nautical terms starboard and port and why these words are used by mariners worldwide, including our ferry crews.
Gangways and floats work together to provide a raised walkway area for passengers to safely walk between a docked vessel and the on-land terminal facility. The float is a floating platform on the water in which vessels dock beside and are part of every terminal in the San Francisco Bay Ferry network. Connected to the float is the gangway with joints at either end to allow the walkway to adjust with the changing tide levels while at the same time giving passengers access between the vessel, float and on-land facilities.
At some terminals with restricted space, the setup of the gangway and float can vary depending on topography of the body of water. For example, the Richmond terminal’s float and gangway is constructed in a way where only one vessel is regularly allowed to dock at a time. This is different from other terminals like the Alameda Seaplane Lagoon terminal or Oakland terminal, where two vessels can dock simultaneously at the same float.
While the set-up of each terminal may vary, there will always be these two structural elements to facilitate safe passenger operations. The next time you are boarding or alighting the ferry, see if you can differentiate the float and gangway sections of your terminal.
