Both models were sold at the same time. Same hull and rig
, different deck. The OD version has a bigger cockpit but less accomodations below. I suspect less headroom below. Could be problem since you are 6"3". I am 5'8" and couldn't stand in the regular version without touching the headliner with the top of my head.
Best way to check the rudder bearings is to try to move the bottom of the rudder back and forth. Should be little or no movement. Hard to do that without hauling or taking a swim. If you go for a sail, you would feel the rudder moving and banging if there was excessive play. Replacing the bearings is a pretty easy job. Wear in the rudder shaft at the bearings is bigger deal. If severe, would require rudder replacment.
