Post Subject: Rudder design

Our 62 foot traditional narrow boat has very heavy steering i.e.the tiller requires a lot of force to have an effect, we have lengthened the tiller but is still heavy, would it be possible to increase the rudder perhaps bring it closer to the propellor.

Post Subject: Rudder design

The position of the rudder is fixed by the tube that runs down through the back of the boat. Whilst it is not impossible to alter this it would be very expensive. First make sure that the rudder turns very freely with the boat stationary. if it is still stiff you have probably got a seized bearing or bent rudder shaft. If it is free to turn then you could see if there is space to weld an extension in front of the rudder shaft (stock) between the rudder and propeller, but be warned that although this may make the steering lighter it may also introduce unacceptable tiller vibration. I am afraid this is very much a "suck it and see" situation. Tony Brooks
