Don, that is a 1970 John Allmand 23 Citation. It had a 165hp straight 6 mercruiser. It has a cruise of 18 knots at 3200rpms but was as fuel efficient as can be. It was in our family since 1970. My great uncle owned it from 1970 to around 1980 when my dad took it over. My dad owned the boat from 1980 or so until 2006 when he sold it. That was 36 years of use in our family and repowered at least 3x. I caught more fish on that boat than any other. I have landed everything from a 100+lb bluefin on a Penn 4/0 senator to coolers full of flounder, weakfish, tog, sea bass, all kinds of sharks, stripers, etc.
Here are some shots and details on her:
