These are not all catamrans but are certainly retro futurist. Spaceship looking watercraft. http://www.messynessychic.com/2016/04/20/river-rockets-of-the-soviet-space-age/?utm_source=sendicate&utm_medium=email&utm_campaign=2016-04-25+A+weekly+newsletter+from+Paris
Just found the website that I was talking about in the previous post:

Lots of soviet inspirations but again the neighbors said that no fabrication at the address in S. Florida.
There is a dude “designer” (Rodriguez? something) in South Florida that recirculates all the designs of that era (some in titanium with gas turbine propulsion and hull aerators etc.) It is dubbed the Rolls Royce of mad boats (they start around 10 mil). I used to daydream looking at the website until his neighbors told me they never see any construction done there. There were some boats sold but I don’t know where they were fabricated. I can’t find the website anymore.
