I wanted to make the world’s fastest yawl, so I made the aft sail bigger, but apparently that means it’s not a yawl anymore! It’s a real ketch-22.

Bunk beds! There’s so much room for activities!
kite rig
There actually exist some boats that use kites exclusively for wind propulsion. This is used to save fuel, and most of the propulsion comes from motors. The kite is controlled by a computer.
Some people have also added kite-style sails to traditional sailboats, but I don’t know much about this.
Here’s one such kite on a catamaran: www.youtube.com/watch?v=oKs_yZFRiKI
What about the null rig where you have zero masts and sails?
Then its a displacement hull power boat.
Could the keel rig work in principle?
I forget what they are called, but there is basically a parachute on a rope that gets dropped into fast deep water currents to tow boats.
That’s called a sea anchor.
Since sailing requires you to push against something (the water) if that same something is the thing blowing in your sails it will just push you without really giving you much control. Instead if the currenents are a lot stronger deeper down it might work but then there’s nothing keeping the sail downright(?) meaning without a comparatively heavy (because water is heavy) weight at the bottom of your sail you will likely capsize or more likely just be at an angle where you’re not accelerating much.
Overall it seems at the very least impractical.
I think the only thing that would work is shooting a sea anchor in the direction you want to go from a deck gun, then pulling it back in.
Aren’t all of these just mimic octopus?
what’s your passive perception
Vertical catamaran is genius
Missing the mimic octopus.

I can’t quite identify the point at which this turns from real to parody

The Flettner is real; Maybe it’s added lower just to blur the line.
