ISA Unica Alloy 40M

A stern arranged over three levels, each stepping down toward the sea, is the detail that sets Isa Unica Alloy 40M apart. ISA is building her for delivery in 2028, a 40-metre displacement motor yacht designed around uninterrupted sightlines rather than enclosed decks. The glass balustrade around the infinity cockpit and the wide windows in the owner's cabin carry that idea through the whole design.

Build and provenance

Isa Unica Alloy 40M is a new-build motor yacht from ISA, a 40-metre monohull with a beam of 8.2 metres and a draught of 1.5 metres, measured at 390 gross tons.

Layout and accommodation

The five guest cabins sleep ten people, and a crew of nine tends to their every need. The owner's suite sits forward on the main deck with its own office and lounge, a double walk-in wardrobe and a sliding door that closes the sleeping area off from the rest of the suite. Two separate dining areas, one formal on the main deck and a second laid with a round table one deck up, mean guests are never asked to eat where they lounge. The fly deck runs to close on sixteen metres, room enough for two separate sun areas and a bar.

Performance and engineering

Three Volvo Penta IPS 1350 pod drives, each rated at 1,000 hp, give her a cruising speed of 15 knots and a top speed of 20 knots. Pod propulsion trades outright pace for manoeuvrability at the dock and a quieter ride at anchor, which suits a yacht built around entertaining on deck rather than covering distance fast.

On deck and at anchor

The stern descends over three levels to a pool and cockpit at the waterline, kept open to the view by a glass balustrade rather than boxed in by solid rails. The Jacuzzi sits up on the fly deck, away from the pool deck below, so sunbathing and a hot soak do not compete for the same space.

Where she lies and how to see her

Isa Unica Alloy 40M is under construction in Italy, with completion due in 2028. Boatcrowd arranges viewings of the build and attends them with prospective buyers, and once an offer is accepted we co-ordinate survey and sea trial as soon as she is ready.
