Her interior arrangement is configured for 12 guests across six cabins. Interior spaces are distributed to support both guest accommodations and shared living areas without compromising functionality. 

The exterior profile is characterized by classic, contemporary lines and an advanced bow. Multiple deck levels create dedicated areas for dining, seating, and relaxation, while teak decking adds the finish quality expected aboard a yacht of this scale. The overall design emphasizes usable exterior space and a balanced connection between the yacht’s interior and outdoor areas.

Performance is supported by a steel hull and aluminum superstructure, with a cruising speed of 13 knots and a maximum speed of 15 knots. A range of 6,500nm, combined with 60,000 liters of fuel capacity and 8,000 liters of fresh water capacity, provides the endurance required for extended cruising.

Available for delivery in 40 months from contract, ISY 164 AVENTURA combines six-cabin accommodations, substantial range, and the backing of one of Brazil’s most established shipyards. Her design, construction, and cruising capability position her as a notable offering within the 50-meter market.
