We have four KaMeWa water jets which are our means of propulsion (instead of a propellor). We also have a SeaState T-Max Rudder on each side. In harbor, the vessel maneuvers by directing the jet nozzles, this makes the vessel very maneuverable. While underway the rudders are used an the ship behaves more like a regular ship but it gives us more ahead thrust since we're not losing ahead to keep the bow pointed in the right direction.
