Onboard Tangaroa

We give people who’ll never take on a project this ambitious themselves a real, unscripted look at two people actually seeing it through — mistakes and all. The Never-Ending Sea Trial is a hands-on boat project channel documenting the real-world modernization of Tangaroa, a 1969 aluminum motor yacht, into a Hybrid-Electric Exploration Yacht. Want to see exactly how our hybrid-electric system works? Sign up to get our Single Line Drawing and Blaine’s video explanation absolutely free. 👉SLD.ONBOARDTANGAROA.COM We focus on practical yacht engineering and long-term upgrades — engines, propulsion, electrical systems, batteries, solar, steering, cooling, fabrication, and problem-solving aboard an older boat. This isn’t theory or quick makeovers. It’s real work, done onboard, with real consequences. If you’re into diesel engines, marine electrical systems, repowers, modern tech in classic boats, and seeing how things actually get done, you’re in the right place.
