I wonder if anyone is familiar with the aforementioned yacht builder? I had never heard of Cascade before however was viewing one for sale (not in the market for one myself). It was a 1961 29’. I was amazed at the design itself. Most sailboats at the time had full keeled/skegged hulls and we’re wood and just starting to transition to fiberglass. This boat, the 29, was built in fiberglass, and had a bulbous fin keel! Way ahead of it’s time and built by Robert A. Smith, of Sparksman & Stephens designers. They were unsure how rugged fiberglass was at the time so they built them heavy. From the little research I’ve done, Cascade tested the fiberglass by shooting a 45 slug into the hull and the bullet was repelled (no pea shooter)! I’m NO expert at yacht design but it appears that Cascade/S&S were the genitors of the modern sailboat design as we know it today. Jist curious as to anyones thoughts, thanks!
