Hi Andrei, I own the M15 you saw recently. It is a 1990 model, hull number 471. After a long search, I purchased it from a very nice fellow in CA and convinced my brother, who was in CA at the time, to pick it up and bring it to our family reunion here in Madison. I had it out on Lake Kegonsa for my first sail last week and absolutely loved it. About a week after I sent the check for this one, another M15 came up for sale locally, so there is at least one more nearby. The dream is to sail the Apostle Islands and perhaps Isle Royale eventually. I would love to go sailing together. Paul McAleavy
