The ISY 115 EXPLORA is a 35.30m (115’10”) new-construction motor yacht built by INACE with naval architecture by INACE and exterior design by Fernando de Almeida. Offering 350 GT of volume, she is constructed with a steel hull and aluminum superstructure to RINA Class and designed for unrestricted navigation. Her explorer-inspired platform combines substantial onboard volume with capable long-range performance, including an approximate 4,000-nautical-mile range at 10 knots and a maximum speed of at least 15 knots.

The interior is arranged across five guest cabins, with the full-beam Owner’s Cabin positioned forward on the Main Deck. Two VIP cabins and two additional guest cabins are located on the Lower Deck, providing a well-balanced accommodation layout with separation between the Owner, guests, and crew.

Exterior spaces are designed around outdoor living and easy access to the water. The aft Main Deck features a jacuzzi, while the upper deck provides dedicated al fresco dining and the open Sun Deck offers generous lounging and sunbathing areas. A hydraulic Z-lift swim platform provides convenient access to the water for swimming and watersports.

With a 30-month delivery time, ISY 115 EXPLORA presents an opportunity to secure a new-build yacht while retaining the ability to personalize key elements throughout the build process, including interior finishes, equipment, and selected technical specifications.

Exterior Deck Arrangement

• Sun Deck Aft
  • The sun deck aft is laid out as a lounging area, with the integrated seating and sunbathing sections built over locker storage accessed through lightweight hatches in the deck. Removable canvas sun awnings on carbon-fiber poles, fitted into flush-mounted bulwark sockets with a battery light atop each pole, shade the space; the poles stow via removable covers when not in use.
• Bridge Deck Aft
  • A dedicated seating arrangement occupies the upper deck aft, centered on a fixed midship dining table and chairs for al fresco meals. A sliding weathertight door with safety glass, matched in color to the exterior windows, connects the space to the interior, with infra-red sensors so the door re-opens automatically for anyone passing through.
• Aft Main Deck
  • The aft main deck centers on a jacuzzi filled with fresh water drawn from the pool tank and discharged to a dedicated pool dump tank, fitted with a manually operated removable hard cover matching the teak decking. A removable stainless-steel external shower (pole shower with telephone handset, plus a separate hand shower) is set into a deck socket on the swim platform, with hot and cold water feed. A second sliding weathertight entrance door, matching the upper deck door in style, connects the deck to the interior.

Deck Finishes

• All exterior decks are teak-clad in traditional 50mm-wide planking, 10mm thick after sanding, laid over faired decks on a lightweight bedding compound with grey calking — with the exception of the storage deck beneath the pool deck. Handrails and handholds in polished stainless steel (AISI 316L) run along stairways and bulwark tops throughout.

Indicative loadout only — the specification references the below as a possible tender/toy configuration sized to the vessel's stowage and lifting capacities; final selection remains at the Owner's discretion.

• Reference tender: Williams 565 or Castoldi 568 (Owner-supplied, foredeck stowage, detachable chocks)
