Seaduction is an extraordinary example of Arthur DeFever's legendary offshore cruising design, thoughtfully upgraded and professionally maintained to a remarkably high standard by knowledgeable, experienced owners. From her gleaming Awlgrip finishes and beautifully preserved teak interior to her spotless, nearly seven-foot-tall walk-in engine room, every area of this vessel reflects an exceptional level of care, investment, and stewardship. Her condition speaks not only to pride of ownership, but to a maintenance and upgrade philosophy that has consistently prioritized quality upgrades, preventative care, and long-term-reliability.
Arguably one of the finest DeFever Performance Offshore Cruisers available, Seaduction represents a rare opportunity to acquire a truly yacht-quality example of this highly respected model. Buyers familiar with the DeFever name understand how difficult it is to find a vessel of this vintage that has been maintained to such a comprehensive standard without years of deferred maintenance or costly projects awaiting the next owner. Seaduction stands apart as a genuinely turnkey cruising yacht requiring no catch-up maintenance.
Designed and built for serious long-range cruising, Seaduction combines the timeless craftsmanship, comfort, and seaworthiness that have made DeFever yachts sought after around the world. Powered by twin Caterpillar 3208 diesels and carrying 1,000 gallons of fuel, she offers the range, capability, and confidence to comfortably explore the Inside Passage, Alaska, Mexico, and destinations beyond.
The highly desirable flush-deck design creates living spaces unlike virtually any other yacht in her class. The expansive salon and galley provide an open, light-filled gathering space for owners and guests, while below decks are three private staterooms, each featuring its own ensuite head and shower. The owner's suite enjoys complete separation from guest accommodations with its own private stairwell, abundant storage, spacious shower, and convenient access to the engine room. Throughout the vessel, refinished teak-and-holly soles, rich solid-teak cabinetry, and impeccably maintained finishes create an interior that is both elegant and inviting.
Equally impressive is the walk-in engine room, offering exceptional access to machinery and ship's systems. The engine room alone sets this vessel apart from the vast majority of comparable offerings and will be immediately appreciated by experienced cruisers, owner-operators, and marine professionals alike.
Seaduction is currently moored in the coveted North Docks at Everett Marina, where premium amenities, convenient roll-up pump-out service, and transferable moorage further enhance ownership and make immediate cruising enjoyment a reality.
