Two German twin-rig trawlers, 'Iris' and 'Janne-Kristin' have been equipped for optimal manoeuvrability and propulsion efficiency with the incorporation of controllable pitch propellers from Schottel.

The two vessels, each 35m long and 10m wide, were recently handed over to German fishing company Kutterfisch. Both vessels were constructed and designed at Nodosa shipyard in Spain for operation in the North Sea. The projects were realised in close cooperation with Reinjes España.

Janne-Kristin and Iris are each powered by an ABC 6DZC engine with an input power of 1,326kW driving a Schottel Controllable Pitch Propeller type SCP 71 4-X of diameter 3.3 m for a speed of 11 knots. The SCP meets the demands of the fishing industry thanks to the adjustability of the pitch of the propeller blades. This makes them suited for a wide range of operating conditions such as manoeuvring, berthing, casting or hauling nets. As a result, the operator benefits from a high degree of efficiency – leading to lower operating costs and reduced fuel consumption.

Janne-Kristin and Iris are claimed to be among the most modern trawlers. They are equipped with a highly automated system for loading and unloading fish containers as well as a reversed bow designed to facilitate navigation and to improve functionality – especially in rough seas. The catch handling deck has been given a high level of automation to minimise heavy lifting and maximise fish quality. The trawlers are capable of demersal and semi-pelagic trawling for a variety of species.
