The boat has always been in my parents garage and seems big but may not be 20’ long. Looking online a bit more it seems like the plans are for the dingy. Zephyr article.
As far as building it – my dad bought the plans back in the late 50s or early 60s. He and 6 engineering buddies built 5 of the boats from the plans. They had a great time doing it. My dad’s never got completely finished but others were in the water and sailing. He died last year so I can’t add any details. That’s why the boat is now available to a good home. If you know anyone who would be interested, or a place where we should advertise it, please let me know.
Hi- we have a Zephyr and plans from Science and Mechanics (craft plans 287). Located in NJ. Hull built and brightwork done. Hardware and mast. Never sailed. On original trailer (have plans for that too.)
