One aspect of optimizing propeller is material that is stronger than conventional this is called stainless duplex steel, the blades can be made thinner and powerful. stainless steel duplex steel Propeller is quieter, has better grip in the water, increased speed and lower fuel consumption.

Their reputation has found some US companies to use these performance-capable propellers.

Propellers manufactured from stainless Duplex steel

They have a reference of about 40 'SD which benefited from their optimized propeller at max speed of 2-3 knots (in Finland, no way to exaggerate marketing, cultural difference).
