“This thing rips when you let her take off, so hold on to your hat!”. So warns Miriam Morris before punching the throttle on the Arc One, a state-of-the-art electric boat that is making its northern Michigan debut this weekend with a series of public demonstration events. As Arc’s company experience specialist and “captain of culture,” Morris is typically the one who oversees the company’s demo days, and she tells The Ticker she never gets tired of seeing the looks on people’s faces the first time they experience the Arc One’s lightning-fast acceleration. Powered by a pair of 1,500-pound batteries and a 500-horsepower inbound motor, the boat can zoom from a gentle cruise to a top speed of 40 miles per hour in the blink of an eye.
