SOME MANOEUVRING DEVICES FOR USE AT ZERO AND LOW SHIP SPEED

The paper is principally about the jet flap rudder and the experimental work that has been conducted on this device. The addition of a jet flap to an otherwise conventional rudder will increase the side force produced by the rudder and hence the manoevrability of the ship, particularly at zero and very low forwards speeds. In order to operate the jet flap rudder it is necessary that the main engine and propeller be operated in the ahead condition so that the slipstream passes over the rudder, and in this respect the device is unlike a stern mounted side thrust unit which can be operated independently of the main engines.
