HM-RAT-2000 stern

Hydromaster HM-RAT-2000 stern is listed as a Stern Thrusters / Retractable Azimuth Thruster within the Bow category. It is typically installed at the aft end of the propulsion shaft line, operating in the vessel’s wake outside the hull. Its engineering role is to convert shaft torque into hydrodynamic thrust for vessel propulsion. The source entry additionally records power 2000.0 kW. The complete model designation should be retained when matching drawings, certificates, service information and spare parts because neighboring variants may differ in configuration even when they share the same equipment family. The exact shipboard arrangement and interfaces remain installation-specific and should be checked against the vessel’s approved drawings and equipment documentation. Where an operating value, tolerance, wear limit or setting is not explicitly stated in the source data, refer to the manufacturer documentation for the exact figure.
