Re: Sailboat Rudder (ROM) Range of Motion
45 degrees either side of center sounds reasonable.. beyond that it's acting more of a brake than anything. Hopefully the boat is responsive enough not to tempt one to hold it over that far very often or for very long. The limitation of restricted motion might be the ability to make a sharp turn at low speeds, eg entering a tight slip...
The best setup we've ever had was a tiller/rudder that could cleanly turn 360 degrees without stops or interference.. the beauty was we could spin the rudder around when backing up for ultimate control and no 'unbalanced' loads. But it was a very responsive boat and tacking rarely involved more rudder action than 15-20 degrees angle.
