The RYNO is an electric hydrofoil watercraft concept. It uses a “V” shaped hydrofoil design and a tilting seat that offers the rider a highly manoeuvrable, quiet yet exciting recreational experience.
Origin of the idea
I’ve been exploring hydrofoil concepts since I started Imaginactive back in 2013. Over the years I have gotten feedback from a lot of knowledgeable people in that field including Kotaro Horiuchi, Robert Innes and most recently Chris Hoffmann who contacted me to collaborate on his Ryno hydrofoil project.
How it works
The main innovation isn’t the “V” shaped hydrofoil that is narrow, simulating the effect of a tire rolling on the ground, it’s the addition of a seat that’s connected to an axis of rotation set at a rake angle to allow the rider to swing themselves laterally. This allows the rider through standing on the deck of the hull with their feet, to roll the craft and the attached hydrofoils side to side to steer, while the rider’s centre of mass stays perched over the centre of buoyancy. A seat and handlebar allow the entire body to come into play as the rider navigates smoothly through the water.
The hydrofoil wing is designed to lift the hull of the craft off the water to offer less drag, more speed, a unique three-dimentional navigation environment and to reduce the jarring effect of piloting craft over choppy water. To keep the hydrofoil stable in the pitch direction (fore and aft) a small stabilizing fin can be used or a gyro stabilization system that adjusts the speed of the propeller in relationship to the pitch angle of the water craft. The rider would simply lean forward to accelerate and to stop would lean back. When sitting quietly in the water, the HF-1 will allow the rider to back-up, spin around and accelerate off in a different direction.
A sizable 15 kW electric motor will power a ducted propeller located at lower centre of the “V” shaped hydrofoil. Lithium-ion batteries located inside the hull will supply the energy needed to propel the craft at 25 MPH over a 30-mile range. The hull has a set of access hatches to allow gear to be stored and the batteries to be removed to be easily charged indoors or from any 110-volt outlet.
What it’s Used For
The Ryno is all-electric, highly manoeuvrable, and dead quiet. Since it is riding on hydrofoils that product no wake, at 25 MPH and 30 miles range it will allow customers to re-enter restricted waterways. It would make a trusted addition to any luxury yacht, boat house or beachfront property.
Of course, like any project, this one will need to be developed further to meet the requirements of consumers and that is what Chris Hoffman and his team are currently working in on. If you are interested in the Ryno Hydrofoil, don’t hesitate to contact Chris directly.
The Industrial Designer
I would like to thank Chris Hoffmann for inspiring us with his vision for a new type of personal hydrofoil. I would also like to thank Martin Rico for creating the images of the Ryno HF concept. Martin lives near Buenos Aires, Argentina. He studied Design at the University of Buenos Aires and now works as a Freelance Industrial Designer. Martin also designed the Atasha robotic flight attendant and the Horus flying superbike.
