A device coupleable to a remote source of pressurized fluid for producing fluid that can be discharged by the device and thereby propel the device over or through a surface. The device comprises a buoyant hull with one or more fluid communicators for directing fluid flow. A nozzle at the distal end of each fluid communicator creates a fluid discharge from the fluid communicator directed horizontally or at an angle away from horizontal. Flexible tubes connect the fluid communicators to the remote fluid source.
