The decarbonisation of maritime transport and the reduction of its environmental impact in general is a subject that has been debated for a long time and various solutions have been imagined over the years. Propelling ships by means of a sail is not a new idea, but in this case it is the approach that is innovative, as well as the company that has decided to invest in this field. At the Movin’On 2021 – a global summit dedicated to sustainable mobility – Michelin turned ambition into action, presenting an innovation created to meet the most pressing challenges facing the future of mobility.

The project presented by Michelin is called Wing Sail Mobility (WISAMO) and is an automated, telescopic and inflatable sail designed to be installed on merchant ships and private recreational boats. Being inflatable, the sail will have a sort of airfoil that will improve its aerodynamic efficiency. This project is the result of collaboration between Michelin’s Research & Development department and two Swiss inventors who share the Group’s “all-sustainable” vision.


The inflatable sail is designed to be a free, universal and inexhaustible propulsive source. The profile of the sail generates thrust for the ship and allows lower fuel consumption, CO2 emissions and therefore a positive impact on the environment.

Designed and developed by the WISAMO project team, the system can be installed on most commercial vessels and recreational boats. Particularly suitable for cargo ships, bulk carriers and oil tankers, it can be installed as original equipment or retrofitted to vessels already in service.
