An indicator of the gathering momentum for cleaner burning, nontraditional forms of propulsion for the U.S. workboat industry can be found in WorkBoa's Significant Boats of 2021. The list of 10 boats is selected annually by WorkBoat magazine's editorial team. What's unusual about the 10 Significant Boats of 2021 is that four of them have departed from traditional modes of propulsion. With two exceptions, it's the first time in several years that WorkBoafs Significant Boats has included anything other than boats powered with traditional diesel engines or gas outboards. The four "nontraditional boats" that were chosen last year were the Chief Potackee Betty Mae Tiger Jumper, the Sea Change, the Nikola Tesla and the James V. Glynn. The 36'7"×12' Chief Potackee Betty Mae Tiger, named after the only female chief of Florida's Seminola tribe, is a glass bottom tour boat with a capacity of 28 passengers that operates out of Silver Springs State Park in Marion County, Fla. It's powered by twin 20-hp Elco electric outboards with four Lithionics 7.5-kW lithium-ion batteries. When needed, the 36-footer has a 10-knot running speed. |
