A sheave assembly comprises: a hub having an inner opening; an insert; a plurality of rolling elements; and a sheave arranged coaxially around the hub to define an annular space for receiving the plurality of rolling elements for rotatably mounting the sheave on the hub. The hub comprises a radially extending aperture which extends between the inner opening and the annular space, the aperture being sized to receive the rolling elements therethrough for inserting the rolling elements into the annular space from the inner opening during assembly of the sheave assembly. The insert is removably mountable in the aperture and is configured to be removed and inserted radially from within the inner opening. The annular space is bounded by an outer race provided by the sheave and an inner race. The inner race is defined by a surface provided by the hub and by a continuous surface of the insert. The continuous surface is shaped to fill the aperture when the insert is mounted in the aperture.

An apparatus (100) for actuating a locking mechanism (12) of a locking sail track car (10) comprises a latch formation (116) disposed in a fixed position with respect to the track (14), a control surface (112) spaced from the latch formation (116) in a hoisting direction, and an actuator assembly (120) for attachment to the car (10). The actuator assembly (120) comprises an actuator (124) for operating a control member (24) of the car locking mechanism, and a latch element (158) connected to the actuator (124) and moveable between a first detent position in which the latch element (158) is not engageable with the latch formation (116) and a second detent position. The latch element (158) is arranged to cooperate with the control surface (112) upon movement of the actuator assembly (120) in the hoisting direction to set the latch element (158) into the second detent position, and is engageable with the latch formation (116) upon subsequent movement of the actuator assembly (120) in a loading direction with the latch element (158) in the second detent position. Engagement of the latch element (158) with the latch formation (116) fixes the actuator (124) in position with respect to the track (14) for operating the control member (24) of the car locking mechanism (12) upon subsequent movement of the car (10) in the loading direction, and urges the latch element (158) out of the second detent position and towards the first detent position such that subsequent movement of the actuator assembly (120) in the hoisting direction to disengage the latch element (158) from the latch formation (116) sets the latch element (158) back into the first detent position.

A lock apparatus is provided for releasably securing a load, such as a sail, to a supporting structure, such as a mast while the load applies force in a load direction. The lock apparatus comprises a lock member attached or attachable to the load and a lock assembly for attachment to the supporting structure. The lock assembly comprises at least one locking element configured to move between a locked position in which the locking element blocks movement of the lock member in the load direction, and an unlocked position, an actuator, and a releasable coupling for coupling the actuator to the lock member. The coupling is arranged to couple the actuator to the lock member upon movement of the lock member towards the actuator in an insertion direction, opposite to the load direction. Subsequent movement of the lock member in the load direction first carries the actuator in the load direction to move the locking element towards the locked position, then causes the coupling to decouple the actuator from the lock member and brings the lock member into engagement with the locking element, thereby to keep the locking element in the locked position to block further movement of the lock member in the load direction. The apparatus is suitable for use as a halyard lock in a sailing vessel.

The hub assembly comprises an input shaft for connection to the input, an output shaft for connection to the output, a coupler for transmitting drive from the input shaft to the output shaft, and a reduction gear assembly. The reduction gear assembly comprises a plurality of layshafts, each layshaft carrying an input planetary gear and an output planetary gear, a carrier for supporting the layshafts, an input sun gear for coupling the input shaft to the input planetary gears, and an output sun gear for coupling the output planetary gears to the output shaft. The coupler is movable between a first position and a second position to switch the hub assembly from a first configuration in which the coupler is directly engaged with both the input shaft and the output shaft and a second configuration in which the coupler is engaged with the reduction gear assembly to transmit drive from the input shaft to the output shaft through the reduction gear assembly.
