The International Windship Association (IWSA) is a growing, member driven association that is encouraging, advising and advocating for the use of wind propulsion technologies in the shipping industry.

IWSA’s objective is to facilitate and promote the technology, applications and general concept of wind propulsion for the global commercial shipping industry and bring together all parties interested in catalysing the development and uptake of these technology solutions. The IWSA will increasingly play a key role in acting on behalf of our members and supporters within this sector in order to shape industry, regulators’ and international bodies’ perception of the concept of wind propulsion.

Membership of IWSA is available to companies and organisations involved in the marine wind propulsion sector along with associate members and supporters that share our vision coming on board from the wider industry, academia, non-profit sector etc.

With the help of our members, supporters within the industry, academia and other stakeholders, IWSA is sending out a clear message: wind propulsion is a serious and increasingly proven option, financially a win-win situation and we are here to work with an industry ready for change.
