Propulsion: ZF Project Disruption
ZF's global Marine and Special Driveline Technology business unit introduced the Project Disruption concept to the public on the opening day of the 2017 Fort Lauderdale International Boat Show. The new propulsion concept introduces contra-rotating technology to conventional inboard shaft line applications. The Project Disruption concept allows shaft line boat builders to harness the benefits of contra-rotating propellers, including increased efficiency, acceleration and reverse authority. The concept changes all of the pre-established constraints of trying to optimize propeller diameter with gear ratio. The concept, intended to interface with a standard ZF marine transmission, is comprised of a strut-housed underwater gearbox which transmits power to two contra-rotating propellers. In addition to providing increased efficiency and acceleration, Project Disruption's contra-rotating propellers will allow boat builders to consider a wider range of transmission ratios than what is possible today given propeller sizing constraints for single propeller shaft-lines. This will allow naval architects the opportunity to better optimize the propeller to gear ratio relationship depending on vessel application and loads. The contra-rotating propellers will also offer improved reversing performance and low speed maneuvering by eliminating the propeller torque that currently affects single shaftline applications. While initially sized for tow sports boats, the concept could be extended to larger propulsion packages, or hybrid systems for a multitude of vessel applications.

Propulsion: Volvo FWD
A revolutionary new concept in marine propulsion, the first Volvo Penta Forward Drive (FWD), debuted at an exclusive event at the Miami International Boat Show. Opening up a new realm for recreational water sports, the Volvo Penta FWD begins with forward-facing dual counter-rotating props with an adjustable-trim drive. This patented and innovative design pulls the boat through the water rather than pushing, with an undisturbed water flow to the propellers. This clean and efficient propulsion system delivers superior responsiveness, acceleration, fuel economy and versatility, allowing for an array of activities behind the boat, including wakesurfing and wakeboarding. Drivers will also be able to customize the wake for different ability levels and feel the difference in tighter high-speed turns, as well as more responsive slow-speed maneuvering and docking. Additionally, the forward-facing DuoProp, with counter-rotating propellers, offers a unique and industry-first symmetrical wake-boarding wake and equally shaped wake-surfing wave on your side of choice. FWD also reduces noise and vibration, and virtually eliminates annoying fumes on deck since engine exhaust is expelled underwater beneath the boat. The adjustable tilt makes it easy to trim the boat for optimum fuel efficiency and comfort when cruising. When at rest with the drive trimmed down, the forward-facing propellers are inboard of the boat making activities like fishing and swimming more practical astern of the boat. The Volvo Penta FWD, coupled with the new-generation marine gas engines, is an unbeatable combination for boat builders, providing higher speeds and better performance with a smaller, lighter engine. The engine and drive system are proven and feature accessible service points for easier maintenance. Dealers and boat owners will also benefit from the commonality of parts across the full range of engines and drives. Most importantly, the builder, dealer and customer have the peace of mind that comes with a fully integrated helm-to-prop solution designed, built and supported by a single manufacturer with an unmatched reputation for customer satisfaction and after-the-sale customer service. The new Volvo Penta FWD and gas engines are covered by Volvo Penta’s warranty with five years of factory protection. The Volvo Penta FWD has been tested and developed with several key boat-builder partners. New boat models featuring FWD will be available starting in 2015.

Propulsion: Rolls-Royce Azipull
The Azipull combines the advantages of the pulling propeller with the flexibility of mechanical drive, and can be linked to any prime mover; diesel, gas turbine or electric motor, dependent on individual customer requirements. It is designed to offer efficient propulsion and maneuvering on higher speed vessels. The streamlined leg and skeg recover swirl energy from the slipstream, raising overall propulsive efficiency. The leg has a wide chord to optimism rudder effect and improve course stability. Azipull is available with a controllable or fixed pitch propeller. Control Pitch propellers give greater flexibility with regard to prime mover selection. With fixed pitch propeller selection the Azipull units must be integrated to the ship and designed into the hull form for the best results, with reduced hull insertion loads. The upper gear housing, steering gear and auxiliaries are from the standard Rolls-Royce azimuth truster range to maximize spares commonality. Rolls-Royce Azipull is available in four models AZP085, AZP100, AZP120, and AZP150. Azipull models can take from 900 up to 5000hp, and are so far directed more towards commercial vessels.

Propulsion: Voith Inline Propulsor
The initial idea was to develop a propulsion system with minimum vibration and noise emissions. The result is a rim driven propeller powered by a permanent-magnetic electric motor. The thruster system requires neither axle nor shaft or gearing. VIPs impress by their prompt steering and can also be retrofitted as propulsion systems or thrusters. If required, the propeller blades can be replaced individually. That is fascinating technology lending itself to a wide variety of applications. Voith Inline Propellers are used as propulsion systems for passenger boats, barges and large yachts. The Voith Inline Propulsor systems are driven by an integrated permanent magnetic synchronous ring motor. The motor windings are housed in the stator, the permanent magnets are housed in the rotor. The rotor is supported by water-lubricated bearings for the radial and axial load. The propeller blades made from Carbon Fibre-Reinforced Plastic are directly connected to the inner ring of the rotor, which eliminates the need for a central shaft or gearbox. The sense of rotation, as well as the speed, is controlled by frequency converters. Thruster housings are pressure-tested to verify water tightness and are filled with resin to encapsulate all electric parts and permanent magnets. The Voith Inline Propulsor is available in nine units from 67 up to 2010hp.

Propulsion: Reintjes Fortjes 1000, 2000, 3000, 4000, 5000
Reintjes from Germany has come with a new innovative pod drive drive system suitable for yachts from fifteen up to 36 meters in length. The Fortjes drive system consists of an upper reversing gearbox, a foundation plate and a non steerable pod with two counter-rotating propellers. Ideal flow conditions are achieved by means of an asymmetrical shaft. This effect is enhanced even further by two counter-rotating propellers. This not only results in considerably reduced cavitation but also in an almost irrational flow at the rudder blade, which makes the drives far more efficient and wear-resistant than other system types. The fixed-pod design, as opposed to steerable pods, has a positive effect on the sailing stability. In practice, this becomes obvious instantaneously. Also in challenging power ranges, the yacht can be safely handled and precisely manoeuvred, which makes the boating experience even more enjoyable and increases the comfort. With its extremely compact design Fortjes not only contributes to a considerable weight reduction, but also saves a lot of space: a drive system with a 5000 series, as compared to a conventional fixed-propeller drive with a propulsive power of 2600hp, needs two meters less installation space and provides the designer with additional room for individual configurations. The Reintjes Fortjes system also offers advantages to shipyards: All components can quickly and easily be integrated into the ship’s hull within just four hours. Here the specially developed installation system plays a crucial role. It takes up the gearbox in the engine room and, below the waterline, forms the basis for mounting the pod. After the foundation plate has been built into the hull, the gearbox and the pod can be connected with each other. The installation costs of this drive train are considerably lower. An important note is that the Fortjes drive system has been designed for use in different hull forms and is compatible with all customary engines. Yachts with a Fortjes drive can be traditionally steered using a steering gear and engine control or, optionally and very elegantly, via a joystick. All steering and control functions, including those for bow thrusters and stern thrusters, can be integrated in one control system. The German Reintjes Fortjes is available so far in five versions; 1000 up to 670hp, 2000 up to 938hp, 3000 up to 1200hp, 4000 up to 2000hp, and 5000 up to 2600hp. There is also at works the smi custom 6000 unit which can be available for larger horsepower engine.
