G3 - Heesen Yachts FOR SALE

G3, the luxury superyacht, is one of just seven yachts in the Heesen 4400 Aluminium series and ranks among the most comprehensively modernised examples available today. Launched in 2008, she received a charter-focused refit in 2017, then a complete repaint with interior renewal in 2021–2022, followed by further mechanical upgrades and cosmetic enhancements during 2024, underscoring her pedigree.

Constructed in aluminium with a semi-displacement hull, this motor yacht blends performance with range. Twin MTU diesels deliver 7,200 hp for a 23-knot top end and a 17-knot cruise. Comfort at anchor is assured by CMC zero-speed fin stabilisers throughout any itinerary.

With design by Omega Architects, her living spaces feel open and adaptable. The main saloon showcases sweeping windows and a crisp, minimalist aesthetic. During the 2017 refit the formal dining was repositioned aft to flow directly onto the main deck terrace. A galley features Miele and Hoshizaki equipment plus a dumbwaiter. The skylounge opens to the bridge deck aft, creating a versatile hub for private or charter entertaining.

G3 welcomes up to 12 guests in five staterooms, attended by a crew of nine. The full-beam owner’s suite sits forward on the main deck with a spacious en suite and a private study that converts to a children’s cabin or massage room. Below, two doubles and two convertible twins each enjoy their own en suite for added privacy.

The sundeck of G3 presents a Jacuzzi bordered by generous sunpads and an open‑air cinema. Aft on the bridge deck, shaded alfresco dining is arranged. Created during the 2017 refit, the beach club unfolds at the waterline and incorporates a gym, wet bar and lounge. In 2024 the swim platform received a full mechanical rebuild. Forward, the foredeck is configured for tender and jet‑ski stowage, carrying a Williams SportJet 375 and four Sea‑Doo Spark jet skis, while a 10‑metre Intrepid chase boat is included in the sale. Additional water toys include two eFoils, a Radinn jet surfboard, five Seabobs, scuba gear with Bauer compressor, an inflatable sailing catamaran and kitesurfing kit.

Winter 2024–2025 works comprise extensive MTU engine maintenance, including a full QL3 service, replacement of all exhaust manifolds, installation of three new turbochargers and the rebuild of one existing unit. Yard periods covered the mechanical rebuild of the swim platform, new teak laid on the foredeck and sundeck, a complete air‑conditioning service, and a superstructure repaint (the hull was refinished in 2019). Steering rams, thrusters, stabilisers and propellers were all serviced, and inside every ceiling panel in the main saloon and guest cabins was renewed during this comprehensive programme of work.

G3 is wintering in Loano, Italy, and can be inspected at short notice. Please enquire for full particulars or to arrange a private viewing throughout the season; she welcomes qualified buyers aboard.
