Well, I thought this was a PEARSON ELECTRA, the cruising version of the more well known PEARSON ENSIGN.
However after looking more closely at the posted pictures, That is not what it is, Sorry!
I am pretty sure this is not an Alberg Design either, looks sort-of 1960s British or European in design. I'll keep looking at my library of boats for a possible match. Since I wrote a lot about hte Electra here, I'l lleave it in case anyone else may someday need info on that design.
The Electra was sort-of a "Mini-Triton" and was designed by Carl Alberg for Pearson Yachts. The Electra actually came a few years prior to the Ensign, and was the original version, but a group of sailers from Long Island Sound apparently approched Pearson about wanting a more racing/daysailing version of the Electra, with a larger cockpit and a fractional rig, initially known as the "Electra Daysailer", the class name soon became the "Ensign" to separate her from the Electra. Pearson never really did sell a huge number of Electras, although they were built for most of the 1960s, as I mentioned, the Ensign gained much mor popularity and has remained an active racing class to the present time.
