a quick release hook and have not appreciated the safety value of towing off a modern tow winch incorporating the new controlled release system. Even in an emergency it still provides the ability for the crew to regain control without dumping the tow. This new position is probably the best compromise, in that the stopper and pendant may be attached keeping the tow wire in line with the pins reducing wear, and yet the load may be transferred back to the winch quickly if required.
The transom incorporates a unique system of tow wire control with towing pins and a hold down lug forward of a stern roller at the transom. The pins are electric/hydraulic in operation with three separate pins, plus the hold-down lug, all operated from the winch station. Each hardened pin slides up and down in bronze bushes and rotates on four roller bearings to reduce wire wear. In the centre of the transom is the 400mm diameter stern

roller, which is balanced, running in spherical bearings with a safe working load of 35 tonnes. The wire hold-down lug may be folded up or down hydraulically. Once locked in the grab position, the lug and pins maintain total control of the wire at the transom, eliminating the yawing effect in a seaway. Meanwhile, for'ard on the fo'c'sle, is a hydraulically driven vertical-type 500mm diameter waist capstan giving a five tonne pull at 20m per minute using a foot-operated switch. Slightly to starboard is the main anchor and cable winch, which incorporates both chain and wire on a hydraulically powered drum. On the bow, a large double-staghorn bollard incorporates the hauling fairlead or staple. When a line is hooked onto the bollard or led back to the capstan for hauling, and power is applied astern, this little beast of a tug just lifts her bum and delivers more power astern than many of her similar cousins can muster ahead.
