We are EXIST-funded at TU Munich / Germany. We build a patented, fully mechanical fin drive, and validate it on the water with pilot partners through 2027.

Our Mission 

Electrification is making boats quiet, and suddenly the propeller is the loudest, weakest part on board. Fin propulsion was always the answer, but until now it existed only as fragile, servo-driven robotics.

“Fin propulsion used to mean fragile robotics. Our patented gear removes the electronics entirely, the simplicity is the invention."

That is why our drive can be built, maintained and priced like a normal drive. No servos, no sensors, nothing electronic to fail in the water.

Our values

Measured, not guessed

Every performance figure we publish is labeled: measured on our prototype, simulated, or estimate. No unlabeled claims, no hype.

Simplicity is the breakthrough

We don't add technology; we remove it. Fewer parts, standard materials, nothing electronic to fail in the water.

Our stage

A boat-tested prototype is not a finished product. Field validation with pilot partners is what 2027 is for, and we say so.

Partners early

We work with a small number of pilot users and collaborators, and we choose them early. Validation on the water.

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.
