Only been half following the steering wheel converstation, but what if you stationed the wheel forward (more like a motor boat) like next to the hatchway, so it wouldn't interfere with the cockpit?
manatee suggested that in post#67 and i responded in post#69.
in an of itself, the suggestion holds merit. in this particular case, the design of the boat would make such a suggestion unworkable. the wheels ( in the original forward helm suggestion, tandem wheels would be used: one to port and one to starboard ) would be in the way of anyone trying to walk forward of the cockpit.
it would be fairly easy to do. the quardrant could be above the cockpit sole. there would be plenty of access for an emergency tiller. the cables could go through the cockpit, at the bottom of the benches, and run forwards on the inner walls of each quarter berth, to blocks at the rear of the cabin. then up to wheels on either side. probably to chain over a sprocket. one behind each wheel. then down to blocks below the level of the companionway. the cable would run below the companionway, between these blocks.
it could be done easier with only one wheel, like a power boat, but then you wouldn't be able to shift your body weight to wind on both tacks. you could do it with a center wheel, if the companionway was offset....but it's not.
