Some years ago and well before he died, I met Bill Crealock
at a weekend boat show
put on by Crusader Yachts, the then dealer for Pacific Seacraft
. He was a true gentleman.
Bill made a short talk about the PSs that he designed (most of them). I remember him saying (and I paraphrase liberally): "Sometimes the stern of the boat has to act like the bow."
What he was saying of course and he went on to explain is that in heavy following seas a wide transom boat will catch the waves and be pushed sideways, sometimes broaching (been there done that- on a Perry designed boat no less). A canoe stern will not react as violently- it will "part the waves" to use Perry's words.
Actually I am not so fond of double enders for several reasons: aft boarding is almost impossible, they limit space aft and in the olden days were tough to build in wood.
But they sure are pretty.
