Set spare 6 blade prop D 185mm for BOW45/80 until '98 This is a 6 bladed propeller suitable as replacement for the BOW45/80 until '98Working 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 bladeprofile 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%.
