It has an 11' beam, which was pretty large for a 31' in 1978. It has the same style keel as an Island Packet - that sort of 3/4 full keel that's integrated into to the hull. She's not the most nimble boat by any means but strong and very comfortable.
Strong and comfy are priorities
as is roominess, though the scale for roominess on a boat is a little out of whack with my perceptions of what i think it should be. i looked at a hunter 28 and thought that i'd be miserable in that thing. for somereason when i get past the stability, and the speed, i get overly concerned with creature comforts. do you mind sharing some pictures of the interior? I have crazy (probably impractical) dreams about playing my ps3 on a 40 inch screen in the middle of the ocean
battery power might make that possible for about five or six seconds.
