SOLUTION is a 46' 1963 Aage Neilsen centerboarder. It has no companionway entrance from the cockpit. Cabin access is just forward-starboard, through a sliding hatch. Odd arrangement but the boat was designed for ocean racing('63), and(I was told) to survive capsize. Maybe that arrangement has kept it racing(which it does a lot of), as it's not a very handy set up for coastal cruising.
