Hi Brown,
As Dave said, it has limited usefulness on some of the ships in SS. It is awkward to use with azimuth drives such as those on Ocean Star, Bugsier 2, and Javelin. It is useless on Red Eagle, which has Voith-Schneider propellers.
For those vessels, you must program buttons for much of the work. Since you can do the same with the keys on your keyboard, why bother?
What is really needed is a pair of joysticks that operate in polar coordinates like the real ship control sticks.
Regards,
Marty
