Could be a few of us on this board with this important date coming up. We owners of Alden Challengers attempted a 50th last year(the first Challengers came out in 1960, building plans date to 1958) and unfortunately, didn't have enough interest to put anything together.
Makes me wonder if some sort of Plastic Classic group recognition get together could be possible? Possibly the early part of this decade? It is a remarkable period in boat design/building history with boat designs many own on this website.
Not only were these boats not forgotten, as well as being in use today, they still have the power to influence boat design as the classic CCA look ebbs ad flows through new boat design.
An ad during the 1960 Boat show below talks of this new strange material "fibre glass". Even suggesting that more boats of this new material may evolve....

Perhaps this milestone for a 50 year old boats that wrung in a new era of sailing is only important to the few owners? Too difficult to define as a change in construction and design of sailboats?
Could be, but I'll be having a little celebration onboard with the our boats 50th season.
