The effect of the propeller surface condition is less important than the hull condition, but significantly more important in terms of energy loss per unit area. Reducing the surface roughness of a propeller prevents marine organisms from anchoring and developing which in turn creates increased drag. Therefore a well-maintained polished propeller is a cost and time-effective asset for a vessel, a low investment with very high returns.
