It is definitely not a B25, but I think B32 is right.My first thought is that looks like a B-32 (Lief Beiley). (It might be a B-25 but they had a lift keel)

The B-32's were great PHRF boats. They sailed well across a broad range of conditions and were pretty forgiving. They would also be a good ORR or ORC boat as well. They typically rate in the 69 to 78 range (which is very fast for a 32 footer from that era). They had very good ergonomics and sophisticated sail plans for that era. My sense is that they were well built and pretty tough. (One fell off a trailer at 60 plus miles and hour and survived in a condition that she could be rebuilt. She was later named 'Broken Arrow".) While these fall on the extreme light side, they were not as much of a one-trick pony as the earlier super skinny ULDB's like Olsen 30, or Hobie 33.
If it comes with serviceable sails it could be a great fixer-upper. A new set of sails would be pretty pricey.I think Jeff is correct. I have seen this particular boat posted for sale a few years back. I suspect I saw it on Sailing A.
