Mystery Sailboat, help identify

[Serrano4657]

I had this sailboat for over 34 years. My Dad bought it in 1974 used and not good shape. It's all fiberglass, about 13 feet long, wood mast, rudder and tiller. A metal swing centerboard, seats are formed into the fiberglass, one bench seat stern and two front seats facing forward. there is no seam between top of boat and bottom, Sails have a sewn on picture of saturn, There no name or model on paper, no hin number on boat either. I think it was made early 60's but not sure. I have never seen another boat like it in 50 years of boating.
Thanks


















it is all
