I noticed in the Haines V19R thread that Opti, Grand Marlin and a couple of others were referring to the ancestry of various hulls, including the Jenks 23 which was derived from a Mustang 24. I've just bought a Mustang and would be interested to read any original specs or test reports anyone might have - the only info I've found so far was in one of Jeff Webster's books.
Strikes me some of you have been boating here a hell of a lot longer than me and might know about these things.
Incidentally, had a look at a Millenium 24 at a dealer the other day, interesting to see how a fairly minor makeover has modernised a 30 odd year old design. Hmmm, a new curved windscreen and a moulded basin module would do wonders for mine.....
