Aluminum Expedition Sailboat BUILT for the Northwest Passage - BOAT TOUR
Step aboard SV Sentijn, a purpose-built aluminum expedition sailboat designed for high-latitude sailing and extreme conditions. In this full boat tour, owners John and Kara Pennington walk us through the design, systems, and practical choices that make Sentijn a true expedition cruising yacht. From her strong aluminum hull and protected cockpit to her warm, practical interior, every detail is built with safety, durability, and self-sufficiency in mind.
Sentijn isn’t just a cruising sailboat — she’s a vessel built for some of the most remote and demanding waters on earth, with the Northwest Passage successfully in her wake.
A huge thank you to John and Kara of SV Sentijn for welcoming us aboard and sharing their inspiring journey with this remarkable boat.
