RE: Safety and the MOB
Do you carry a dinghy? On your boat getting the dinghy into the water and the lifeless body into the dinghy may be the answer. Then you would at least be out of the cold water while help is summoned.
Otherwise, a tackle rigged from the highest strong point you can find, to a lifesling style lifering will get the body up the side of the boat to the deck. I don't think there are any stanchions on your boat strong enough for that job, so you will need to rig to the radar arch. A snapshackle onto a padeye on the side of the radar arch, up as high as your petite wife can reach, then hauling the mutipart tackle from the side deck where she can grab you as you rise from the water.
Practice it once to see if it is at all feasible. The result of your trial may be that you wear your PFD and harness a lot more, because now you have confirmed that going over the side will surely be fatal.
