Abstract: Disclosed is a marine steering assembly having a steering wheel pedestal, a steering output member, a manual steering mechanism and an auto-pilot drive. The manual steering mechanism is connected to a steering wheel. The manual steering mechanism is retained by the steering wheel pedestal for manual control of the steering output member. The auto-pilot drive is connected to the steering output member and provides automatic control of the steering output member. The auto-pilot drive is aligned with and located adjacent the steering output member. The steering output member, the manual steering mechanism, the pedestal and the auto-pilot drive are accommodated within an outer casing.

Abstract: Disclosed is an assembly for assisting in the attachment of an applicant such as a winch to a surface (e.g. deck) of a watercraft such as a sailing boat.

Abstract: A thruster is adapted to be laterally mounted through the hull of the vessel and has propulsive ducts for opening to respective sides of the vessel and an inlet to the inboard end of both of the ducts, the inlet being at least partially provided by a tunnel having an internal cross-sectional area greater than that of the ducts, the tunnel at least partially surrounding each of the ducts and opening to each side of the vessel.

Abstract: Rope-holding characteristics of a winch drum (2) are determined by a staggered array of pyramidal protuberances (12, 14, 17, 19) on its surface. The staggering is such that there is no true circular path round the drum within the array, and a rope wound on it in the hoop direction is deflected sinusoidally.

Abstract: A windlass assembly includes a single-turn gypsy for engaging the line and/or chain of an anchor rode of a water craft. This has to be driven from a drive shaft, but also has to have the capacity to rotate relative to the shaft under the influence of the anchor as it is paid out. A lever is movable between positions where it engages drive to and disengages drive from the gypsy. It is biased (e.g. by a spring) towards the engaged position, but in its other position can be pressed onto the gypsy to control the friction to which the latter is subject while rotating relative to the shaft.
