Her interior is arranged to make effective use of volume across the yacht. The main salon and dining area are configured for clear movement, with large windows bringing light into the principal guest space. Accommodation for ten guests in five cabins gives the layout flexibility, while ensuite guest spaces and crew accommodation for four support privacy and efficient service flow.

Exterior areas are planned around usable deck space rather than excess. The upper deck includes sheltered seating and dining, giving guests a protected area for daily use. The sundeck adds a Jacuzzi and surrounding sunpads, while the aft deck provides open seating and straightforward movement across exterior zones. For a yacht of this length, her 23'5" (7.15m) beam supports a confident exterior footprint.

Performance is defined by an explorer-style specification. She reaches a maximum speed of 13 knots and cruises at 11 knots, supported by a 3,000nm range. Her 35,000-liter fuel capacity and 15,000-liter fresh water capacity strengthen autonomy, while her steel and aluminum construction gives her a durable foundation for extended cruising.

ISY 90 EXPLORA is a compelling Inace yacht for a buyer seeking strength, range, and practical volume in a compact size. Her Fernando de Almeida design, five-cabin layout, and explorer specification create a capable yacht with clear appeal in the 90' (27.41m) category.
