I like small yachts like this one, which were produced by a few boat builders in the early 80's, I had a Jaguar 21 and guessing by the colour this one might be a Hunter or similar.
Really simple, fun and easy to sail, they are really versitile evolved for club racing back then, they also make a great day sailer or over nighter easy to get into our local crowded harbours.
I spotted this guy going off for a mid week sail on his own, it probably took minutes to rig those sails redy to hoist and get going.
Cheap to buy, cheap to run, generally they sail well although can be a bit bumpy if the weather gets up due to their light weight, what's not to like.
