The testtbed for the E motion hybrid system is a Lagoon 47, one of the company's most popular early models. New developments and components for the E motion system are installed in the Lagoon for on-water testing.
The original 10 ton cat came with twin 27 hp diesel engines. These were replaced with two nine kw electric motors, which turn bigger props than the original diesels.
The boat is equipped with 12 rooftop 12 volt solar panels, which directly recharge the main 144 VDC battery pack. |
