At sea the hard part is not reaching the casualty — it is the last twenty metres. A helicopter arrives quickly and then has to hoist: a winch operation over a moving deck, in a swell, with rotor downwash. A lifeboat can come alongside but takes hours to get there. Both work; both have a failure mode that begins where the other one ends.
BECCARII lands on the water.
MEDEVAC from a yacht or cruise ship
Minute 0
Departure from the coastal base — from a quay, a car park or a beach. No helipad.
Flight
Direct to the vessel’s position.
On arrival
Sets down on the water beside the ship rather than hovering over it. No hoist, no downwash across an open deck, no crew working at height above a moving target. The patient is transferred at sea level, the way a tender would do it.
Return
Lifts from the water and flies to the hospital — where it lands on ordinary ground and, if needed, drives to the entrance.
Domains: fly · VTOL · swim
Search and rescue
Search from the air with the endurance to keep going, then set down on open water to recover a person from the surface. Take off again from the same spot. The vehicle does not need a mother ship, a davit or a recovery cradle — the amphibious hull is the boat.
Offshore support
Platforms and wind farms are served today either by a helicopter that needs a deck slot, or by a crew transfer vessel that needs a weather window. A machine that can land on the water beside the structure, or on a small deck, or on the shore, is not blocked by either constraint.
Coastal interception and border patrol
Fly out, settle on the surface, wait — quietly and cheaply, because floating costs almost nothing compared with hovering — then lift and pursue. Endurance on station is the whole point, and it is exactly what a machine that can rest on the water has.
Why this works
- Sealed amphibious hull. The vehicle floats and moves on the surface; it is not an aircraft that survives a ditching.
- Vertical take-off from water. No run-up, no ramp, no recovery.
- Distributed propulsion. Eight electric units; with two inoperative it lands safely on the remaining six.
- Endurance. Surface operation costs roughly twenty times less energy than flight.

Polar and ice operations
Drift ice, pack ice and the water–ice transition zone are an environment where load-bearing capacity changes over metres. A large track contact area holds the vehicle where a wheel breaks through, and a sealed hull lets it cross the open water between floes. An aircraft can reach that environment; it cannot stop in it.
Why the architecture fits the sea
The decisive design choice is that the propellers sit inside the tracks. The same structure serves as landing gear on touchdown, propeller guard, ground drive and buoyancy element. There is no separate float set, no separate undercarriage and no separate running gear to carry as dead weight.
The hull is sealed and amphibious. Propulsion is distributed across eight independent electric units; with two inoperative the vehicle lands safely on the remaining six — over water that is not a detail but a condition of dispatch.
The architecture is protected by a granted patent family with priority of 7 June 2012, including US9364766B2, CA2875745C and EP2858730B1, spanning more than 50 jurisdictions.
Frequently asked questions
Can it land on open water?
Yes. The sealed amphibious hull allows it to set down on water, recover a casualty from surface level and take off again.
Why is that better than a winch recovery?
A hoist operation in a swell, at night, is one of the most demanding manoeuvres in aviation. Working from a deck at surface level removes the hover, the line and the rotor downwash over people and equipment.
Can it service an offshore wind farm?
It needs neither a helideck slot nor a transfer vessel alongside a ladder, so several dispersed turbines can be covered in a single sortie.
What happens between water and shore?
It swims into the shallows, drives out onto the beach and continues inland. No transfer, no second vehicle.
