Hank George, of Blue Heron Battery, is an engineer who has a background working in the nuclear industry. Designing his own components, he was cruising with lithium power over a decade ago, years before most people. And he’s helped many other boaters do the same. In addition to his expertise, what has impressed me with Hank as I’ve gotten to know him over the past months is the clear way he’s able to explain complex topics with generosity and patience.
