The hydrodynamic laws behind contra-rotating propellers (CRP) efficiency
About Twenty-five years ago, the newly formed Steerprop delivered its first propulsion units to the river cruise vessels River Aria. The propulsor design was also novel, with double-ended, dual propeller units that offered unique efficiency and maneuverability. Since then, the Contra-Rotating Propellers (CRP) has proven itself time and again on a wide range of vessels, from river cruises to heavy-duty offshore ships, high-speed coast guard vessels and icebreakers.
