Apparatus is provided for manoeuvring a ship having a Z-type propellor structure. The propellor structure has a propellor shaft powered, via a clutch 39, by a main engine 40. The apparatus has a handle 4, a synchro 22 and a potentiometer 26. The synchro 22 detects rotation of the handle 4 about its own axis, and transmits a signal S1 dependent upon the angle detected. The potentiometer 26 detects the angle through which the handle 4 pivots, and transmits a signal S3 dependent upon the pivotal angle detected. The signal S1 and S3 pass to a control device 32. 0n receiving the signal S1, the control device 32 transmits a control signal S2 to a rotary drive 33 which pivots the propellor shaft 35, and so effects steering. Depending on the magnitude of the second signal S3, the control device 32 transmits either a second control signal S4 or a third control signal S5. The second control signal S4 is transmitted to slippage control means 36, 37, 38 associated with the clutch 39, and the third control signal S5 is used to control the speed of the main engine 40 via a governor motor 41. <IMAGE> |
