The ferry was assembled by Hornblower Cruises and Events.
From the press release:
"The new 1,400-horsepower Hornblower Hybrid will run on a combination of energy generated by clean Tier 2 diesel engines, hydrogen fuel cells, solar panels and wind turbines. Power will come from a proton exchange membrane fuel cell that turns hydrogen into electricity. In addition, solar panels and wind turbines will help power the vessel. Efficient Tier 2 diesel engines kick in to cover additional energy needs."
