This local photo is over 100 years old, I still can't get over the cool "river bike" that person must have built. Has anyone else tried to build something similar?

Love one of those, maybe I’ll treat myself this xmas

That looks like so much fun! It reminds me a bit of Regent's aircraft that are currently in development.

They're making electric ekranoplanes (ground-effect aircraft) that launch from hydrofoils. Sort of a super fast alternative to regional boats or ferries.
