Though superyachts require intricate, specially designed systems across board, motorboats are far more easily customizable. The Piening Controllable Propeller is a green alternative to traditional systems, available with 4 or 5 blades.

The “green tech” propeller is designed to use hydraulic technology instead of the standard oil-based system. The hydraulic pitch control uses ordinary water and boasts very low operational costs, low noise and vibration, and environmentally-friendly design.

Though conventional, oil-operated versions are also available, the propeller’s true innovation lies in the its hydraulic system which operates well under pressure without using any type of oil.
