This is the story of building an ECO 6 catamaran sailboat, designed by Bernd Kohler. The boat was built with considerable advice from another boat builder, David in New Zealand. David's advice was provided through multiple e-mail messages along with many photographs showing his construction of the ECO 6. Much gratitude to David, and also to designer Mr. Kohler and to many friends who offered assistance at critical times during the build and at the launch of the boat. Construction spanned a 15 month period, ending with the launch in September 2023.
