Solomon Technologies has sold a Electric Wheel motor drive unit to Hobie. "Hobie has advised Solomon that it will use the first ST-58 for R&D and prototype purposes." The spec sheet says it can be used in 60+' catamarans. http://www.solomontechnologies.com/st58.htm
Will we see a Hobie cruiser ala Lagoon or Fountaine Pajot in the near future or will it be a flying Adventure Island?
