Description

2021 XO DFNDR 9   

Winner: Motor Boat Awards'
Best Adventure Boat of the Year 2023


The Ultimate PNW Adventure Machine

Price reduced for quick sale


While other boaters are huddled on the shore waiting for a perfect weather window, the XO DFNDR 9 is already halfway to the San Juans. Designed in Finland to conquer the Baltic Sea, this aluminum center console crossover is the water-borne equivalent of a Mercedes G-Wagon. It blends the high-speed performance of a premium commuter with the go-anywhere utility of a military-grade vessel. Whether you are commuting through the Puget Sound in a December gray-out, fishing in a heavy swell, or pulling up directly onto the rocky shores of Sucia Island, the XO handles the Pacific Northwest with a level of confidence fiberglass boats cannot match.

Why XO Aluminum vs. Fiberglass?

If you've looked at other adventure boats, the XO DFNDR 9 takes it to a professional level.

  • Military-Grade Integrity: While fiberglass is brittle and prone to cracking, the XO features a 10mm military-grade 5083 aluminum backbone. This rigid "survival cell" doesn't flex or delaminate; it punches through heavy seas and handles rocky landings or submerged logs that would sideline a composite boat.

  • Deep-V Performance: The signature insulated deep-V hull is legendary for its silent, sharp ride. It slices through PNW "square waves" with precision rather than pounding over them.

  • Rugged Luxury: Ditch the "plastic" feel of competitors. The XO blends workboat toughness with premium European refinement, featuring heated suspension seats and high-end ergonomics.

Exceptional Condition – A "Better Than New" Rare Find

DFNDR1 is meticulously cared for in near-new condition. Originally a factory demo built to showcase the absolute best of XO's options, it has been pampered by a perfectionist owner.

  • Stored Indoors: Kept in a heated shop, away from the elements.

  • Freshwater Pedigree: Run almost exclusively by the owner in freshwater, 
     preserving the engines and systems.


  • Upgraded for 2025: optimized with brand-new Quicksilver QS4 props (not even sea-trialed yet!) and brand-new heavy-duty Odyssey AGM batteries installed in Sept 2025.

  • Go Anywhere: Includes a custom 2024 Tuff Trailer—a triple-axle, heavy-duty rig rated for twice the boat's weight.

An amazing boat at a great value!
Don't miss out!
