The Kamewa Type-A Controllable Pitch Propeller for boat
Reliable, cost effective, and hydrodynamically efficient the Type-A CPP builds on the success of the well-proven XF-5 CPP design. Available in a range of sizes, covering powers from 0.5-75MW, the Type-A CPP is suitable for both naval and commercial applications, and has been designed to meet current, and anticipated future CPP market requirements.
The new Rolls-Royce Kamewa type-A hub is available in over 40 hub sizes for 4 or 5 blades. |

E3 (E-cubed) is a propeller that features innovative technical solutions in its shell, which are combined with the use of materials and treatments so far only applied in advanced technology fields. These innovations guarantee an absolutely superior resistance to mechanical shocks and galvanic corrosion, by no means comparable to the performances of common feathering, folding or solid blade propellers for boats.
Thorough studies and tests have been carried out over several years for the development of the project, allowing to obtain an extremely reliable product in a particularly slim body.
All this guarantees a long endurance propeller with a wide range of applications, making E3 suitable for all race and cruise boat sailing boats.
The adopted solutions are in line with the latest navigational trends, always oriented towards innovative materials and technologies capable of exalting modern boats' performances.
The feathering 3 blades for boats propeller E3 (E-cubed) is available either for shaft-drive and S-Drive.
E3 is built completely with high-strength and high corrosion resistance stainless steels and has a micrometric pitch-setting device allowing to set the most appropriate pitch from the outside.
E3 doesn't require disassemblage of its parts in order to be installed or removed and doesn't require any hub puller, therefore it can be installed in few minutes easily even underwater. |

SCHOTTEL controllable-pitch propellers for boats (SCP), manufactured by SCHOTTEL-Schiffsmaschinen GmbH (formerly WPM), are marine 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. |

| Rolls-Royce is a market leader in the supply of Kamewa® and Bird-Rolls-Royce has many years of experience in the design of fixed pitch propellers for boats (FPP). The characteristics of our Bird-JohnsonTM and Kamewa® FPPs provide good fuel economy, low vibration/noise levels and minimal cavitation. They are usually individually designed for the specific vessel to deliver the optimum in propeller efficiency. |

An innovative new propeller for boat 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. |

| 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 for boats. 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 Racing 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 for boats are an extra safety. At the same time low fuelconsumption is important for the boatman, because with long boat boot expeditions filling stations are often not close by. |

| The 5-bladed FASTER Propellers for boats with a blade area ratio of 80% are specially designed for a quiet run and a minimum on vibrations and noise. FASTER 5-bladed propellers are extremely suitable in marine cases where a propeller with limited diameter must be applied. The 5-blades have large influence on the pressure differences. The higher the number of blades, the smaller will be the pressure differences, what results in less noise. FASTER propellers are cast from Manganese-bronze and on request we can also supply these in Nickel-Aluminium bronze. All FASTER Propellers are dynamically balanced. |
