Yup, you read it right. In September 2014, Intrepid Powerboats announced a new natural gas hybrid fuel system technology. The new fuel system is already being used by commercial fishermen, charter boats, ferries, tugs, as well as larger ships, the military and recreational users.
Boaters can save as much as 50 percent on fuel immediately by making the change; these savings directly impact high-fuel-usage boaters, many of whom rely on their boat for business. In many cases, the fuel savings recover the cost of the fuel system in one year for frequent boaters.
Performance of natural gas on a boat is the same or better than with its original fuel, with the added benefit that natural gas emissions are 90 percent cleaner (green alternative fuel) than diesel and 70 percent cleaner than gasoline and do not produce any exhaust odor or smoke.
This will become more important in the next few years when regulatory requirements for emissions are expected to be a lot more stringent.
