The bigger the better.
Mr Schenck has a valid point about helm leverage. In nearly any case the more leverage you have on the helm the better it will be for your endurance and patience under way. The biggest potential hassle in going to a large wheel is if the gearing ratios of the sterring system are set up too long-- i.e., that too many revolutions of the steering-wheel axle are required to turn the rudder enough to navigate the boat. I have written extensively on the as-built flaws of the 54, and this is one of them. The boat was given a plenty big wheel but still requires something like 4-1/2 turns lock-to-lock.On our Raider 33 we had a 36- or 40-inch wheel. Going under the cockpit I toyed with the ratios by removing turns of cable off the quadrant and later adding some on. We ended up with about 2-1/2 turns lock-to-lock and the ability to make the boat come about with only about two or three spokes' worth of turning the wheel. Coming from a tiller set-up to this, it doesn't get any better. The boat was as nimble as a Formula-One car whilst racing (which is where my dad got the idea-- those cars turn lock-to-lcok in about 1 rev).Do not now say, 'Well, I cruise, I don't need that.' Nearly ALL so-called 'high-performance' ideas have their corresponding application in leisure use. The as-built 54 repeatedly wearies helmsmen (and the autopilot) with endless cycling of the helm back and forth, excerabated by the rudder having been moved too far forward to accommodate the stupid dinghy garage (don't get me started on THAT again!). By comparison a boat like our Raider would be very comfortable on a long trip-- seeing as we Cherubinis, with the genetic curse of a big space between the first two toes, could steer it from sitting on the coaming!!JC
