I am in the same camp as others here that exclaim "what's the big deal?" As will gilmore aptly noted, it's the direction of the rudder which, of course, points the direction the stern moves. As long as the driver understands that a boat steers from the rear then confusion is impossible. Therefore, when introducing a new sailor to helming, that's the point that should be emphasized.
As far as wheel steering on a sail boat, their only real purpose is to provide the additional power needed by the below deck rudder machinery... which, interestingly enough... is often a short tiller arm or quadrant variation. Back in the day, it was common to see very long tiller handles on small 60 to 80 foot schooners and the like.
Funny thing is, on those old wooden wheel equipped ships... frigates, 4th rate, 3rd, 2nd etc.. the pulley system was NOT reversed like it is on modern boats. Turning the wheel to the right pointed the rudder to the right, not the boat, just like a tiller arm does, meaning you turned the wheel in the opposite direction you wanted to go... think about it... back in those days you didn't tell your new driver to "steer it like you're driving a car"

there were no cars... there were no steering wheels for that matter....

. At the helm, there were always at least 2 quartermaster's mates at the big wheel, four on the big ships, standing on both sides... but commands were given relative to the rudder direction... It would have been confusing to relate the commands to the wheel instead of the helm/rudder.
Finally, I think there are some sailors that think that, in some misguided way, having a steering wheel instead of a tiller somehow makes the boat look higher quality.

Dude........ nothing could be farther from the truth. In fact, a 25 foot boat with a dinky wheel (because the cockpit is too small) looks unbelievably pretentious.... okay...I'll say it... bring on your flames... it looks stupid, ridiculous, absurd!!!!

You just don't need a wheel on a boat under 30ft...... It's (forgive me)
Power boat-ish.... but that's just my opinion. (Geez, this response somehow turned into a rant. Forgive me, please........... I'm old)
