The ISY 150 EXPLORA's interior is arranged with functionality and privacy in mind. The owner’s suite provides a dedicated retreat, while the remaining guest cabins are laid out to maximize flexibility for family or groups of friends. Each cabin benefits from thoughtful proportions, ensuring both comfort and efficient use of space across extended itineraries.

On deck, her arrangement emphasizes versatility. The aft deck is designed as a multipurpose area, with the capacity to host a pool or be adapted for a variety of uses. Expansive outdoor spaces connect seamlessly to the interior, increasing her appeal for both relaxation and entertaining during extended passages.

Performance is built around reliability and endurance. With a maximum speed of 14.5 knots and a cruising speed of 11.5 knots, she offers steady and efficient operation. Her engineering and fuel capacities provide a range up to 5,500 nautical miles, enabling transoceanic routes without compromise to comfort or autonomy.

ISY 150 EXPLORA stands out as a rare opportunity to secure a newly built explorer yacht of her size and specification. With her steel construction, five-cabin layout, and ocean-going capabilities, she is positioned as an attractive acquisition for an owner seeking immediate availability and proven performance.
