External pitch adjustment (no tools required for pitch adjustment), increased motor efficiency, very low drag under sail, legendary reverse, and great reliability.
SCHOTTEL controllable-pitch propellers (SCP), manufactured by SCHOTTEL-Schiffsmaschinen GmbH (formerly WPM), are propulsion systems that can be used with almost any type of vessel. The power spectrum ranges from 600 kW to 30,000 kW, with propeller sizes varying between approximately 1.5 to 8.0 metres.
Advanced calculation methods allow the controllable-pitch propeller systems to be optimally adapted to the vessel’s hull form, thereby maximizing efficiency and minimizing noise generation.
The simple structure of the SCP guarantees a high level of user-friendliness, and the robust design keeps maintenance requirements to a minimum and ensures it a long service life.
Unlike a fixed propeller which efficiently transfers motor power in only a limited r.p.m. range, the Controllable Pitch Propeller guarantees optimal power transfer throughout the whole r.p.m. range of an engine. Advantages AWM-Controllable Pitch Propeller: more speed in calm sea, more power reserves in rough sea, lower fuel consumption, improved manoeuvring and the maximum power transfer throughout the whole r.p.m. range of an engine Advantages of low fuel consumption: Motor-sailing yachts and motorboats has to cope with changing sailingconditions and wether types. In contrast with Regatta yachts (they can get help from a Regatta organisation) motor-sailingyachts and motorboats have to have thrust in themeselves when something goes wrong. In this kind of situations AWM-Verstelbare Propellers are an extra safety. At the same time low fuelconsumption is important for the boatman, because with long boot expeditions filling stations are often not close by.
An innovative new propeller for sailing yachts ...
The Kiwiprop™ is a unique cost effective feathering propeller that eliminates gears, aligns the blades with the streamlines not the shaft, minimises corrosion potential from the lightweight composite blades and offers users easy variable pitch adjustment. In the Kiwiprop™ the individual blades are always free to "weather vane" in the actual water flow, to a minimum drag position so don't cause autorotation.
This modern light weight three bladed feathering propeller has proved much smoother and quieter in operation than equivalent two bladed units and offers the additional benefits of variable pitch, fully lubricated, minimal corrosion potential and the full reverse thrust.
