Loss of Rudder/Propulsion
If the vessel experiencing rudder loss is a twin screw then the problem is lessened. Use can be made of the revolutions of each engine to control the direction of the vessel.
In a single screwed vessel, a different situation applies and can best be met by towing an object offering drag such as:- fish basket, bundle of nets, a 20 litre partly filled drum or bundles of boards attached to a length of line.
When secured to the centre of the transom, this arrangement will keep the vessel moving in a straight direction.
To steer the vessel it will be necessary to attach the line (with the drag attached) to one quarter of the vessel, with a lighter line made fast to the other quarter.
Alteration of tension on the light line will cause a change in direction of the vessel.
If the rudder has been lost it must be remembered that there is a good possibility of ingress of water into the vessel via the rudder post area. Make sure the area is secured.
If the rudder is in place but damaged, use knotted chain or rope across the trailing edge to position and secure in midship position. Some rudders will have an access hole for lifting gear. This could be used to hold shackles and enable the rudder to be tied off.
With the use of the rudder and failure of the mechanical or hydraulic drive the situation is different.
