Model sat in basement for about 25 years unfinished I built the keel at work from a piece of scrap steel installed keel & went on with other projects finally in early 2025 decided to finish The Sail boat Optimist only to find that there was no parts as Graupner stop selling parts . I have only built one other sail boat the Soling 1 Meter so #2 sailboat was a series endever. And it sailed just great first time.
