Leaving aside plastic boats like the Wave what production performance cats are favored by single hand sailers these days?
I owned and sailed a Nacra 5.2 in the 1990s off the beach in Santa Cruz, usually crewed. Back then the Hobie 17 was probably the top selling single-hand designed boat. There were still some Hobie 14s in use, and Nacra had the 5.5 Uni and then later I believe the Inter17.
All of these boats were optimized for single handing by having fewer controls, all uni rigged initially, and lighter/smaller for one person.
The Nacra 5.2, after returning it to it's factory style rigging was quite complex, including daggerboards, two sails, lots of adjustments and rudders that didn't quite "kick up". Especially for sailing off of (and back onto) a beach, it was a handful for one person. It was also heavy for one person to right (something I never needed to do single handed) at 350 lbs. When I moved from the area I thought if I got another beach-cat someday I would look into a more dedicated singlehanded.
Jump forward to now and it seems that all the performance boats are optimized for two person crews. Most have three sails now, meaning sailing them as intended by one person is going to be even more challenging. Nacra builds the Nacra 15, Nacra F16, Nacra 17, and Nacra F18 - but all are designed for two-person crews. Hobie only has the F18 boat and the antiquated H-16 in fiberglass.
Back in the 1990s there were the Hobie Singlehanded Championships every year which had divisions for both Hobie 14's and Hobie 17's. Has single-handed cat racing died off? (I know about the A-cat, but those seem too expensive and exotic).
I'm a bit over 6' and 220lbs. Looking at all the current Nacra's for instance, I come closest to the min. crew weight on the smallest - the Nacra 15 (but it's designed for two juniors). Anyone single hand those? On the other hand the 15', 16' and 17' are all pretty close in weight, and if I were going to sail one with only the main maybe the 17 would be the best choice - the bigger main.
My thinking is that F18 and larger boats are best sailed by crews of two, even though, of course some people successfully sail them singlehanded.
Beach launching won't be an "every time" event, but something beach able still seems like a plus.
