Oscar Patented PressurePores™ technology
URN is caused by cavitation, the formation and explosive collapsing of gas bubbles on the blade surfaces of marine propellers.
When Oscar’s PressurePores™ are precisely placed on marine propellers, cavitation will reduce significantly. Full scale sea trials on a high cavitating propeller have shown a 10dB URN reduction in the range most damaging to marine fauna.
Cavitation also causes serious damage to propellers, rudders and hulls. Our technology will extend their life and performance, and improve onboard comfort too.
