porto-based architect, pedro ramalho, shares his vision of an energy autonomous yacht called ‘P1’. measuring 55ft (17m) in length, the concept proposes to use only wind and solar power, meaning no more polluting and costly diesel engines.

to achieve the right combination of solar and sail efficiency, ramalho envisions the P1 as a transformable vessel. with a retractable mast, keel, and rudder, it can turn from an energy-efficient, electric propulsion solar boat to a fully rigged sailing yacht. this set-up aims to open new ways and possibilities for traveling around the globe.

with 60 sqm of photovoltaic panels, the boat can generate up to 15kW/P from the sun, powering an electric engine and charging batteries. ideally, this solar power could be used for port and coastal navigation.

the keel and rudders also retract, enabling optimized performance for all conditions

 

 

as the sun is not a continuous energy source, limited to daylight hours and fair weather, the design also combines the technology of a sailing vessel. deploying a mainsail and jib in a fully automatized process, the P1 can boost its range to reach all shores with the performance and sustainability of a traditional sailing yacht.

the retractable sailing rig functions as an articulated triangle with a sliding vertex – the sails unwind from a furling inside the masts
