Diminutive but amazingly powerful, the Rotor Tug is capable of manoeuvring a 1,000ft-long 250,000-ton bulk carrier in and out of harbour. Thanks to its revolutionary propulsion system the Rotor Tug is blessed with spectacular agility, a high rate of turn, and the ability to move rapidly sideways and exert a high proportion of its 75-tonne bollard pull in any direction.
