Cmirpuri,
That's understandable. Most of the tiller driving on that boat will be done sitting on the windward coaming. After a day that will feel totally natural! For mooring, the tiller pivots up at the base, and you can stand on the centerline and drive in total control.
Didn't mean to try and talk you out of your idea of a wheel. You'd be happy with that for sure. But there are trade offs. I suggest that you give the tiller a fair shake, and then look into the conversion process if it seem more natural. But try and drive a wheel boat first.
In the end, it's all a about you enjoying your boat.
