Understanding Cruising Boat Batteries

Gio and Julie Cappell I Pelagic Blue Cruising

Gio & Julie Cappelli are both graduates of Skagit Valley College’s Marine Maintenance Technology Program and are USCG licensed Masters. They have sailed more than 20,000 miles through the Pacific aboard their Malӧ 39 and are both owners of Pelagic Blue Cruising Services, where they help cruisers prepare themselves and their boats for offshore cruising. In addition to running Pelagic Blue, they teach offshore cruising workshops with John Neal of Mahina Offshore Services. When they’re not at sea you can find them planning their next big offshore cruise and helping their clients get ready to set sail for distant shores.

Gio is an ABYC certified Marine Diesel Engines and Marine Systems Technician. He’s been working on cars, boats, and houses for decades and previously worked as a fish biologist and motorboat operator instructor for the Department of Interior. He loves a good mechanical or electrical challenge and is a champion spearfisherman. His life goal is to spearfish in every ocean on the planet. Brrr! Julie used to be terrified of electricity but is now ABYC certified in Marine Electrical and a NMEA certified Electronics and NMEA2000 Installer. She’s been trying to grow a set of gills her entire life, and has worked as a marine biologist, scuba instructor, and expedition leader. She loves a good electrical or cruising logistics challenge and is an absolute genius when it comes to tracking down the gremlins hiding in your boat’s networks. Her life goal is to meet every species of whale in every ocean on the planet. There are about 94 currently recognized species and so far, she’s got 16!
