predecessors of similar size with a number of clever design features. They include individual steerable quartz nozzles, making her perform more like a Z-drive ship- handling tractor tug than a traditional working towboat. "Independent steerable nozzles give her exceptional manoeuvrability," says her skipper, Lance Brown, a senior master for the Auckland company Thompson Towing who was contracted to trial and prepare the PT May for delivery. "This includes being able to move sideways, which is a step ahead from most standard twin-screw tugs." The nozzles are top-hung and have 35 degrees of steerage to port and starboard, taking a total of 12 seconds lock-to-lock. Shipco made her steering gear with TQM autopilot and electronic steering levers. There are steering stations in the wheelhouse, the flybridge and the winch station. The amount of grunt this little workhorse delivers
from 900kW is most impressive. During her trials she comfortably delivers a bollard pull of 17 tonnes ahead, with a couple of sneaky tonnes still up her sleeve if the skipper wants to put the hammer down in an emergency. The impressive bit is the 14 tonnes she pulls with relative ease astern, once again reinforcing the value of the nozzles and directional thrust. "This makes her a very powerful and lively vessel that can be used to best advantage with fingertip control," says Lance. Not only is she nimble in confined spaces when traveling, but also the steering is by one nozzle only and she remains very positive to the helm. Shipco also designed and built the PT May's fenders, a 1.1m-wide sweep of double-loop tyres 500mm deep around the bow and extending to the for'ard shoulders.
