SPS

Stress Distribution: Since the blades are fully CNC machined, the root sections’ fillets are precisely made according to design specifications, rather than being hand-finished like monoblock propellers. This ensures proper stress distribution as per the engineer’s analysis.
Vibration Reduction: The precise CNC milling of the entire blade provides the most accurate geometric and mass tolerances which are critical for reducing hydrodynamic and mechanical vibrations, thus ensuring smoother operation and a longer lifespan for the propulsion system components.
The SPS is unbeatable in the lead time production.
The hubs are made in various standard sizes and are available at all time.
Their corresponding blades are produced in our factory in short time.
The gather design also means that an SPS propeller or its components can be air-freighted in a reduced-size crate, whereas a whole monoblock propeller would incur significantly higher transportation costs.
The gathered design means as well that a replacement of a conventional propeller requires weeks of work in a dry dock, while a SPS propeller or individual blades can be replaced in hours by a scuba diver in port.
