NAV Navigator

The complete propulsion unit

For more than 50 years, the SCHOTTEL Navigator (NAV) has been a byword for a reliable and compact propulsion unit suitable for use on an extremely diverse range of vessels. In principle the NAV, an adaptation of the SCHOTTEL Rudderpropeller (SRP), is a largescale mobile outboard plant, providing the vessel with 360 degrees steerable manoeuvrability.

Compact design

All main components of the SCHOTTEL Navigator are mounted on the base frame, which also accommodates the daily fuel tank. A canopy protects the complete unit. A diesel engine is used as the prime mover. The electrical and electronic monitoring elements are installed in an integrated switch cabinet. The clutch between the prime mover and the Rudderpropeller transmits the power through a flexible coupling and a universal shaft.

Propulsion: Rudderpropeller (SRP)

The SCHOTTEL Rudderpropeller is mounted at the rear end of the base frame and can be hydraulically raised or lowered in vertical direction by means of a depth adjustment facility. This serves to ensure maximum propeller thrust with all vessel draughts by maintaining the correct propeller immersion. For maintenance purposes, the Rudderpropeller can be pivoted to the rear using hydraulic or mechanical lifting devices. The propeller is equipped with an anti-cavitation plate to protect it from damage, or alternatively with a nozzle, if higher bollard pull is required.

Simple Installation

Installation is fast and simple, since the Navigator merely has to be bolted onto a foundation prepared by the shipyard. Thus every kind of floating object can easily become motorized. The NAV is characterized by its wide variety of applications. As an extra service SCHOTTEL offers customers installation drawings according to the customer’s requirements. Our sales and engineering teams will be happy to provide assistance and advice.
