“My first love is boats. If I hadn’t had kids, I probably would have got my skipper’s ticket and joined a sea action group like Sea-Shepherd or Greenpeace.”

Those are the opening words on Fair Winds Trading Co’s website from its founder and chief executive Madadh MacLaine, who subsequently set up the Zero Emissions Ship Technology Association (ZESTAs).

ZESTAs secretary general Madadh MacLaine tried to build her own prototype zero emission vessel in 2015.
