Walt Thirion

Walt and his partner Jane live aboard SV Wanderlust, their 2014 Passport 545 Aft Cockpit, exploring remote anchorages. They are currently in the South Pacific. A sailor of nearly two decades, Walt writes about seamanship, self-sufficiency, and the joys and challenges of voyaging life, which he chronicles through Voyage of Wanderlust. A former serial entrepreneur, he brings the same curiosity and problem-solving mindset that built his career ashore to navigating the complexities of life at sea. From ocean crossings to weeks spent quietly at anchor, Walt shares insights for sailors who dream of living with both freedom and intention.
