Rudder roll reduction for small ships

Roll motion on a ship can be very uncomfortable, and in the extreme, dangerous. It is possible to use the rudder to reduce roll motion as has been demonstrated by others on naval and coastguard vessels. For this study, five controllers were chosen and designed to implement a rudder roll reduction system as part of an autopilot on a fishing vessel. A numerical model and a physical model were prepared for testing these controllers. The results from the numerical model indicate rudder roll reduction does not work for the fishing vessels tested. These results are suspect for several reasons.
