Elco Motor Yachts, the Athens, N.Y., electric motor manufacturer, showcased its EP4000 AC on the Hunter e36 Hybrid sailboat. “There’s no smoke, no noise, no vibration,” Elco senior vice president Kevin Kearns says. The AC motor is 93 percent efficient, compared with 45 percent for most diesel motors and 25 percent for 2-stroke gasoline motors, he says. Kearns says that at $8,500, the cost is comparable to a diesel system.

Operating cost is about 8 cents a nautical mile. The 12-volt batteries are rechargeable from shore power, solar panels, a wind turbine or a 14-kW generator. “You can get to hull speed instantly with a generator running and dead batteries,” he says.
