Interesting to read that this is a Pilot and Tug - 20 metre vessel with a bollard pull of 19 tonnes.
Newbuild cost was £1.8 million and was built at the Vestvaerftet shipyard, of Hvide Sande, Denmark.

Knab is a twin screw vessel of 20.3m in length overall, with breadth of 7.4m and service draft of 3.3m. The vessel is heavily built, with a raised forecastle, to deal with the extreme weather conditions prevalent in the area during the winter months and complies with the requirements of DNV 1A1 TUG R1.
Power for the twin screw propulsion system is supplied by two Volvo Penta D30 diesels, each developing 720bhp at 1,400rpm. The twin three blade propellers rotate within fixed Kort nozzles and are driven via Heimdal reverse-reduction gearboxes. High performance 'Becker' rudders are installed and controlled by Tenfjord steering gear and independent Rolls-Royce controls. A Hundested fixed pitch bow thruster is powered by a dedicated, variable speed Volvo Penta TAMD 74Q diesel engine of 350bhp. On trials Knab produced a bollard pull of 22 tons and maximum free running speed of 11.4 knots.
The towing gear fitted aboard Knab leaves no one in doubt as to its viability as a tug.
A Hydracraft T16176B100 twin drum hydraulic towing winch has a line pull of 25 tons and maximum brake holding load of 80 tons. Each drum is equipped with a 110m towline of 32mm diameter Dextron 12 plus (12 strand Dyneema within a protective cover). Hydracraft also supplied the T10438A100 hydraulic 'tugger'winch located on the port side of the after deck. Mampaey supplied a quick release towing hook for secondary, or emergency use, and Karmoy Winch the capstan, aft, and the combined capstan and anchor windlass on the foredeck.
