Set spare 6 blade prop D 185mm f/BOW45/80, until '98This is a 6 bladed propeller suitable as replacement for the BOW45/80, until '98 Working in close collaboration with the Maritime Research Institute Netherlands (MARIN), the world-famous hydrodynamic laboratory, VETUS has optimised the performance of its thrusters. This has been achieved by utilising a unique propeller blade profile, which creates little or no cavitation.As cavitation produces unwanted noise, this new blade design offers a major reduction in the operating sound levels for VETUS bow thrusters. Moreover, the application of this new propeller has reduced the current consumption by up to 10%.
