Hello Gardner
I think you are mistaken !
You would turn wheel clockwise to go to starboard when facing forward. After you shunt you would be facing the other end of boat and still turn wheel clockwise to go to starboard. Remember that you change position and are facing the other end of boat so you would turn wheel in same direction relative to yourself even though the wheel is turning in opposite direction on shaft. During the shunt you would have to rotate in different direction to rotate rudder 180 degrees unless you had rudder that can rotate 360 degrees. You may be able to lock front rudder after shunt in center and only use aft ruder to steer with. You could put arrow on wheel pedestal to remind you which way to turn wheels to rotate 180 degrees but I think it would become second nature after a few shunts.
This is the way I understand it but if this is incorrect maybe Rob or someone else can explain it.
Happy sailing,

I was doodling about steering with a single wheel, and it seemed to me that if you did that, then turning the wheel clockwise would cause you to steer starboard on one "tack" and port on the other. That would get really confusing if every time you shunted, you would have to steer the opposite direction. Am I wrong on that?
I was playing with the harriette style rudders, where you would not have to turn them 180 degrees. If that could be combined with some sort of tiller arrangement, it would save space, but wouldn't you then need 2 tillers?

I was assuming that the twin wheels would be locked 90% of the time, functioning like a single wheel, with the option of adjusting the rudders individually when in the mood for extra speed.
But if it's more complex than that (such as locking is easier said than done), a single wheel is fine with me. The simpler the better.
I look forward to the Sol2 developments. I've always liked the whipstaffs on the Etap monohulls, and was excited to see them on the rapscallion rendering. If there's a way to make them work, that would mean taking up even less space, plus more of the feel of a tiller.

Twin wheels are not much fun if you are going to do a lot of shunting. Better is to have both rudders connected to a single wheel. Means you can't use them to crab sideways, but this is not a big deal. If you wanted to do this, then a seperate control could be added.
A whipstaff takes up less space than a wheel, but as you point out, they struggle with the 360 degree turning circle. I have a few ideas for this using adjustable length steering lines, which will be tried on Sol2, where cockpit room is at a definite premium.
