 Peace Boat is a social enterprise and an international NGO based in Tokyo whose mission is to create awareness and initiate action to inspire social and political change in the world. Peace Boat brings its mission into reality by organising educational and advocacy voyages on a large passenger ship. For the past 30 years, following a social business model of its participants paying the cost to come on board, Peace Boat has been organising 3 to 4 global voyages per year reaching out to thousands of people in Japan and abroad.

The Peace Boat Ecoship Project

The Ecoship project is a transformational programme to construct the planet’s most environmentally sustainable cruise ship, which is scheduled to sail in 2020. It was initiated by Peace Boat in 2013 as a response to the need for the “greening” of the cruising industry as well as to forward its commitment to peace and sustainability.

The most emblematic aspect of the Ecoship will be its 10 retractable and photovoltaic sails that are expected to push the vessel with an average of 10% of the propulsion power at a speed of 17 kn and with a wind intensity of 40 kn with a relative orientations from 20° from the aft to 20° to the bow.

Wind energy will be harnessed as well though its 10, equally retractable, wind turbines that will deliver 300 KW with a wind speed of about 12m/s. This energy will be mainly used when alongside, to minimise carbon emissions in the ports of call.

Our holistic approach to energy efficiency includes,additionally, a diesel-electric dual propulsion – with hybrid generators and electric motor – energy saving features – optimised hull shape, anti-water drag system, integrated heat recovery and internal reuse for waste energy, natural air circulation system to reduce needs in HVAC – and the use of other renewable energies – solar, thermal and kinetic.
