What years ?
I'm assuming your referring to the full keel Triton, I beleive the last year it was made was 1967. The Alberg was first made in 1962, I don't know when it was last produced. There is a thread here somewhere that discusses LOA-LWL (overhangs) with a lot of comments by Jeff H. I would read it before buying one these boats for serious offshore cruising. However if your heart is set on one I hope you find a good one. The thread is in sailboat design forum.
