It reminded me of Steven K. Roberts' "microship", an amphibian pedal/solar/sail micro-trimaran - https://microship.com/ https://microship.com/ . He started his 'technomadic publishing' in the 1980s on bike. His BEHEMOTH was famous; it's on loan to the Computer History Museum. See https://www.youtube.com/watch?v=dItCJUuFY4U https://www.youtube.com/watch?v=dItCJUuFY4U for a BBC interview with him. He then switched to microships for a while. His description of struggling against the wind and current to make shore made me not want to go that route. To be clear, Roberts's bike and microship were all human-powered, with no motor assist.
