An extensive research in cavitation tunnel has been carried out in the design phase of this propeller, to avoid noise and vibration.
Cavitation levels and performance at cruising and hump conditions are greatly improved.
FH 4 125
This four blade propeller is used by most of the major shipyards for superyachts applications able to achieve speed above 30 Knots.
The blade shape and design is calculated to match the specific requirement of propellers working in tunnels.
FH 5 105
This propeller has been developed to give minimum vibrations on heavy fast boats.
Tested with success on american's fast "sportfisherman", it became a new line in the year 1989. No noise or vibration. Also used when tunnels are needed to work in shallow water. Smoothness guarantee.
