Tropes involving vehicles capable of travelling on and/or under water (or other liquids if need be). Can also include amphibious vehicles.

Vehicles can include anything from rafts, rowboats, aircraft carriers, submarines, or even [[Radio/GTARadio special helicopters that can go underwater]].

Despite the name, GunboatDiplomacy does not go here -- it refers to the use of displays of strength to intimidate others into doing things your way, and is named after a real-life trend of using fleets for this purpose.
