NAVICO FATHOM e-POWER

Fossil-fuel marine generators have long served the AC electrical needs of boaters while away from shore power. But let's face it, gensets can be finicky, are high-maintenance and smelly, and create intrusive noise and, in some cases, dangerous CO emissions. Navico aims to shift that paradigm with its Fathom e-Power system.

At its heart, Fathom e-Power uses advanced lithium-battery technology to provide auxiliary electrical power for boats ranging from less than 20 feet in length to yachts. "Lithium batteries for marine applications have gained substantial traction in the last decade," says Eric Lindquist, VP and general manager for power systems at the Navico Group. "They last longer, charge faster, reduce weight and maximize space, as well as save time and money in the long run (versus lead-acid batteries)-all the while minimizing negative impacts on the environment." The upshot: Lithium battery systems are well on the way to rivaling marine generators as an auxiliary power source.
