A fellow Sailnett'er has an Edson wheel installed in her O'day 25. (She hates it)
I call it a disaster. Due to the transom-hung rudder, it required cutting holes where there really shouldn't be a hole, and it just added totally unnecessary complexity to a small, simple boat.
If you simply cannot function without feeling like you're behind the wheel of an automobile, if you really enjoy losing all sense of weather helm, to aid you in properly helming your small boat, and if you absolutely must
have that "Master and Commander" pretentiousness onboard your modest yacht, then I highly encourage you to jam an Edson wheel and pedestal into your O'Day 25.
In fact, I can donate two instrument pods for yout speed and depthfinder to really
clutter up your cockpit.
