  • Commented on Gizmo's big work & play display, advice please
    There's a nerd side of me that likes every latest electronic gadget. It battles with the Luddite side of me, born out of Windows crashing on me 200 miles offshore in a storm, and autopilots that spin me in circles....
  • Commented on Gizmo's big work & play display, advice please
    I've got a couple different approaches to this on the Barbara Ann. If you are passing through Rockland, stop in at Journey's End Marina and I'll give you a tour of the project....
  • Commented on Panbo: surveys, comments, & Paris
    Must be something in the Maine air. I'm another sailor geek that has a composer in the family. My daughter Christine (http://www.christinesouthworth.com) is an MIT graduate that now composes avant-garde classical music that has been performed in Carnegie Hall and...

    Thanks for the mention of Hybrid Propulsion. You also bring up a couple excellent points. Early hybrid boat projects often undersized the motors because of the difficulties of dealing with the high DC voltages needed for larger motors, and the...
  • Commented on HYMAR, can Nigel find the electric drive grail?
    I'm converting a 57' S&S sloop to hybrid electric right now in Rockland, Maine. My reasons for doing this could go on for pages but but essentially it was to re-trim the boat more forward and to get rid of...
  • Posted Hybrid Electric Conversion to Panbo Forum
    Hi Ben - John LeMole at Gemini Marine suggested that I get in touch since I'm right down the road. I'm converting our S&S 57' sloop Barbara Ann to hybrid electric propulsion at Journey's End. There's a whole lot of...
