James,
You used the magic word there "expected" lots of boats of all types are good candidates for conversion to electric, as long as the owner expect to travel at displacement speeds.On Apr 20, 2011, at 1:11 AM, Eric wrote:James,
I knew that someone would bring that up, but I have to say that a canal boat is not quite the same type of boat as "a 1980 288 Cruisers Yacht VillaVee w/ Twin 454's". I don't think that many owners would spend much money to swap out their 28kt top speed for a top speed of less than 10kts. While I could build a conversion that would get a lot closer to the "normal" cruise speed of 20kts, operating at those speeds would be difficult to sustain for as much as an hour.
That said, I do believe that Dragonfly is a good example of a well executed hybrid, not all electric, conversion. Because a canal boat is only expected to operate in full displacement mode, it makes a much better candidate for electric drive.
Fair winds,
