And efficiency increases by around 30%.

The world's first fixed solar sail in the tried and tested crab claw shape.
This sail shape is particularly efficient because the air turbulence close to the boat is less disruptive and the wind in the upper part enables even more efficient propulsion.
The university in Yverdons-les-Bains, HEIG-VD, is currently calculating the energy gain with different shapes and curvatures.
According to preliminary calculations, the gain is 25 - 30% more than when using electric motors alone.
The sailing tests on Lake Neuchâtel (see video below) in summer 23 already gave us an idea of this.
And at anchor or in the harbour, the SOLARRIG provides shade and collects power from the sun at the same time. (see picture above: Prototype 2)

Passenger ferries transport sustainably, environmentally consciously, cleanly and quietly.
Supply and disposal ships in southern archipelagos protect the endangered ecosystems.
Long trips around the world are also possible with a solar boat. Motorboat captains who think sustainably become "solar sailors" - and even in calm conditions they can sail at 5 knots.

solarrig gmbh (sarl) aims to develop and test a solar sail for ferry, transport and leisure catamarans.
The study carried out by the University of Applied Sciences Western Switzerland, HES-SO, in 2021 serves as the basis for the bachelor's thesis.
Following successful practical trials, production partners are to be found for a joint venture project.
Marketing will take place directly or via partners.
