Some time ago sailors used to look for small wheels to open up the space around the cockpit, especially to be able to walk around it from the helm chair. Later on we began to emulate the racing boats and started seeking them big destroyer wheels. It is no secret that the bigger the wheel the less force is necessary to operate the helm. For racing boats besides lessening the load it provides a more precise way to steer without killing speed. For an offshore boat we look for a compromise in wheel size that will allow to sit comfortably while lessening the helm forces. Seems to me that coastal cruisers nowdays come with a much bigger wheel than necessary, I guess the "cool' factor sells boats. Some opt to take off the wheel while at anchor and others install folding wheels. If your boat does not have a tiller, what is your choice?
