AVENTURER is currently offered as a 3-year lease-to-purchase option with zero interest.

Aventurer is an exceptional 85' Dutch-built Jongert motor yacht, meticulously constructed in 1986 to German Lloyd's classification. Her build incorporated more than 40,000 man-hours dedicated to the interior alone. She was engineered with the systems and redundancies typically found on much larger yachts and has completed both Atlantic and Pacific crossings under her own power.

Aventurer is highly versatile, comfortably accommodating up to 10 guests in four staterooms, with separate crew quarters ensuring privacy. A media room converts to a queen berth for additional guests or crew. Uncommon for a yacht of her size, she offers a generous aft deck with seating for 12, a full bar, a day head, and an expansive flybridge.

Featuring transatlantic range, a steel hull, aluminum superstructure, and extensive system redundancies, Aventurer is a proven long-range voyager. She is equally well-suited for short coastal cruises, extended passage-making, and exceptional entertaining.

Maintained with an open checkbook through multiple refits, Aventurer meets modern standards while retaining her refined Dutch heritage. Most notably, a $2 million “bow-to-stern” refit, completed in late 2021, included a comprehensive redesign of both the interior and exterior spaces, elevating her to an exceptional level of luxury and sophistication. Blending classic Dutch pedigree with modern comforts and premium equipment, she represents true yachting excellence and must be seen to be fully appreciated.

Aventurer accommodates up to 10 guests in four well-appointed staterooms, offering a versatile and comfortable layout ideal for both private ownership and charter use. The yacht features a spacious full-beam Owner’s stateroom, complemented by three additional guest staterooms, providing flexible sleeping arrangements for family and guests.

A dedicated media room further enhances onboard living and converts to a queen berth, allowing for additional guest accommodations when needed. Separate crew quarters for two ensure privacy and efficient service, with accommodations discreetly arranged away from guest areas.

This thoughtfully designed layout delivers exceptional flexibility, comfort, and functionality, making Aventurer well-suited for extended cruising or charter operations.
