The XLS: Extra large and extra strong
For tall ships and Superyachts!
Its remarkable solid is what makes the VARIPROP XLS stand out the most. Like the VARIPROP Blue Water, it offers a large blade surface for high thrust, excellent sailing properties thanks to low drag, as well as perfect handling during harbour manoeuvres.
The construction and design of the VARIPROP XLS are in accordance with the propeller classifications for commercial shipping.
SPW is the only manufacturer of feathering propellers in the world to offer this model for a maximum engine output of up to 550 KW/750 HP. The VARIPROP XLS is available up to a size of 62” (almost 1.6 m in diameter).
The XLS model was designed for tall ships and super yachts that do not have a controllable pitch propeller system installed. It can easily be mounted on conventional shafts.
The VARIPROP XLS has some unique features compared with other feathering propellers:
Separate externe Steigungsverstellung (patentiert)
Independently adjustable external pitch control.
Forward and reverse pitches can be changed in just seconds — even underwater!
Benefits: Custom fine tuning (in micrometer-small increments) of reverse thrust vs. prop-walk. (For most owners, eliminating prop walk is more important than maximizing reverse thrust.)
VARIPROP XLS allows you to customize that balance for optimum control, maneuverability and safety. Independent fine tuning of forward thrust means that VARIPROP XLS delivers the best possible performance (speed, thrust, fuel economy) in forward without compromising reverse performance – and vice versa
Werkseitig montagefertige Lieferung
Integrated shock absorber (patented) build into the VARIPROP XLS hub
Benefits: dramatically reduced shock loads on gearbox and drive train, permits shifting at higher speeds without damage, preserves preset pitches by eliminating hard limit stop impacts
The entire drive train benefits: longer cutlass bearing life, minimized wear on gearbox, clutch plate, bearings.
German precision engineering, robustness and long life
Benefits: All XLS-VARIPROP are sealed to avoid loss of grease from the housing during operation. This ensures long life of the mechanical parts and also substantially extends service intervals.
Made following the ISO 9001 quality standard
Custom made propeller vs. mass-produced competitors every VARIPROP is built to order-consistently 100% up to stringent specifications for reliable, smooth and efficient operation.
Gears are 35% - 50% larger and stronger than competing props for substantially improved service life.
Comes fully assembled
Benefits: VARIPROP XLS mounts on your shaft just like a solid propeller. No disassembly.
