A Reaction Ferry is a boat pulled by a static cable piece meant to transport personnel and cargo on a river bed in a stable manner akin to a naval cable car. During the Locust War, Reaction Ferry's became a principle marine transport amongst the Stranded as higher tech Imulsion powered vehicles became harder to find and maintain.
These boats were built upon a flotation device, usually out of foam or wood. The ferry is than walled by metal sheets and scrap to prevent accidents. The ferry is controlled via a turn wheel which controls the overhang cables supporting the vehicle.
During the Lightmass Offensive, Dominic Santiago convinced Delta Squad to go to "New Ephyra" Outpost as he has personnel connections with the local Stranded and he knows a vehicle that could transport Delta Squad to the Lethia Imulsion Facility, so they could place down the Sonic Resonator and map out the Locust Hollow.
On the way to meet up with Chaps Aspho Gas Station, they found a Reaction Ferry and proceeded to sail the boat to the other end of the bridge. They had a brief firefight with Locust Drones, with Marcus and Dom shooting out the lights underneath the bridge and turning the Drones into a snack for the Kryll.
