The ISA GT45 is the steel-hulled flagship of the yard’s Granturismo line, a 44.3-metre tri-deck drawn by Enrico Gobbi that trades the Viper’s sprint speed for range and volume. Where the sport models chase knots, the GT45 is built to cross oceans in comfort, carrying 432 gross tonnes of interior on a high-tensile steel hull with an aluminium superstructure. Twin Caterpillar C32 engines give an easy cruise and a reach of 4,500 nautical miles at 10 knots, enough to link continents without routing around fuel. Gobbi’s exterior balances the mass of three decks with long glazing and a clean sheerline, so the yacht reads as elegant rather than bulky. Inside, five cabins host ten guests, with crew quarters for a team of nine, and a beach club that folds open to a sea-view lounge and integrated gymnasium. This is a yacht for owners who measure a boat by where it can take them and how well it lives once there, not by top speed. Semi-custom by nature, she allows real input on layout and styling while drawing on the engineering depth of the Palumbo group. For a buyer weighing a 44-metre displacement yacht, the GT45 offers Italian design and genuine transoceanic capability.

The GT45 is tuned for endurance, not pace. Twin Caterpillar C32 engines push the steel hull to around 15.5 knots flat out, but the number that matters is 4,500 nautical miles at a 10-knot cruise, enough to link continents on a single fill. The high-tensile steel hull and aluminium superstructure give the displacement platform the strength and sea-keeping for long open-water passages, and the 432 gross tonnes are carried low and stable. This is a yacht built to shrug off a crossing rather than skim across a bay, and every propulsion choice serves range and quiet running over sprint speed.
Enrico Gobbi’s exterior is the GT45’s strongest argument. Three decks could easily look stacked, but long horizontal window bands and a clean, unbroken sheerline stretch the eye along the hull and keep the profile elegant. The foredeck carries a social lounge rather than just ground tackle, the side decks are generous, and the aft arrangement opens to a beach club at the waterline. Finishes can run from the grey hull of the early renders to classic white, and the detailing stays restrained throughout. The design reads as a considered superyacht, not a volume exercise dressed up.
Five cabins host ten guests, with the owner given the volume a 44-metre displacement hull allows, including full-beam proportions and the quiet that steel construction brings. Gobbi’s interior leans on natural materials, soft neutral palettes and the light from those long windows, giving the saloons and dining area an airy calm. Crew quarters for nine keep guest and service circulation separate, which matters on a yacht intended for long passages and extended time aboard. The accommodation is arranged for genuine living at sea rather than short charter hops, with stowage and systems scaled to the range.
The beach club is the social heart, folding open to a sea-view lounge with an integrated gymnasium, so exercise and relaxation happen at the waterline. Above, three decks give distinct zones: a main-deck saloon and dining area, an upper-deck sky lounge, and a flybridge with space for a spa pool, bar and sunbathing. The foredeck adds a quiet forward lounge away from the aft traffic. With this much deck spread over three levels, guests can gather or disperse as the day demands, and the crew of nine can service all of it to charter standard.
Built in Ancona by ISA Yachts under the Palumbo Superyachts group, the GT45 is classed for unrestricted navigation and backed by a builder with its own refit and service yards across the Mediterranean. Asking prices for new builds sit around 26.5 million euros, with recent brokerage examples trading between 21.5 and 26.5 million depending on year and specification. As a semi-custom platform she allows real owner input on layout, styling and systems while keeping the engineering depth of a larger group. For the buyer weighing her against other 44-metre displacement yachts, the GT45 offers transoceanic range, three decks of volume and Italian design pedigree in a single, well-supported package.
