Sail it for awhile
You should sail your boat for awhile. After you're used to your boat, you'll have a better idea of what to do. Going from tiller to wheel has some trade-offs. In terms of handling, the C-27 is more responsive with a tiller. Assuming that you have end-boom sheeting now, you'll have to convert to mid-boom sheeting with a track on your cabin top (which is also less responsive and harder to control from the helm). Otherwise you won't have the necessary headroom at the helm.The wheel makes things a bit more roomy in the cockpit under sail, but it takes up room at anchor or at the dock. Also, unless your cockpit is designed for a wheel, it's a bit tough to move by the wheel going fore or aft.A lot of folks will disagree with me, but I'd vote against it.
