I have a problem with my latest model (I hesitate to call it a boat!!) so I'm looking for advice on how to fix it.
PD Donald propulsion is provided by a water jet with steerable nozzle. The pictures are to give an idea of the hull shape. The problem is that it is very difficult to travel in a straight line. 🤔 Very easy to turn, and almost spin on the spot, but controlling it to sail straight is virtually impossible. I have reduced the throw on the steering nozzle, but it hasn't made much of a difference.
Any suggestions on how to fix this would be most welcome. My thoughts are I need to add something like a keel sticking down below the hull to give some lateral stability?
