Frequently  asked questions 


Quick answers to common questions, all in

one place

How does it work?

Instead of a spinning blade, our drive moves flexible fins in a controlled, wave-like motion - the way fish generate thrust. A compact, patented mechanism converts ordinary motor rotation into that motion, purely mechanically. No servos, no electronics, no exotic materials.

Why has nobody built this before?

Which boats is it for?

Is it proven?

Nature solved efficient propulsion four hundred million years ago. Our mission is to finally bring that solution to boats - simple enough to build, robust enough to last.
