G3 is one of only seven yachts built in the Heesen 4400 Aluminum series and stands out as one of the most thoroughly refitted examples on the market. Delivered in 2008, she underwent a charter-optimized refit in 2017, followed by a full repaint and interior refresh in 2021–2022, and a series of mechanical and cosmetic works in 2024.
Built in all-aluminium with a semi-displacement hull, G3 delivers both speed and range. Her twin MTU diesel engines generate 7,200 hp, supporting a top speed of 23 knots and a cruising speed of 17 knots. She’s equipped with zero-speed CMC fin stabilizers.
Styled by Omega Architects, her interiors are open, fresh, and flexible. The main salon features expansive windows and a clean, modern finish. The formal dining area was moved aft in her 2017 refit, opening directly onto the main deck aft. The galley is fully equipped with Miele and Hoshizaki appliances, and a dumbwaiter system. The skylounge, opens onto the bridge deck aft, offering a flexible space for entertaining.
G3 accommodates up to 12 guests across five cabins, with room for nine crew. The full-beam master suite is located forward on the main deck and includes a generous en-suite, and a private study that can be converted into a children’s cabin or massage room. The lower deck includes two doubles and two convertible twins, each with en-suite bathrooms.
G3's sundeck features a Jacuzzi encircled by sun pads and a full outdoor cinema system. The bridge deck aft is arranged for shaded alfresco dining. The beach club, created during the 2017 refit, folds out at the waterline and includes a gym, wet bar, and lounge area. In 2024, the swim platform was mechanically rebuilt.
Her foredeck is configured for tender and jet-ski storage, carrying a Williams Sportjet 375 and four Seadoo Spark Jet Skis, a 10-meter Intrepid chase boat is also included in the price. Additional toys and watersports equipment include two eFoils, a Radinn jet surfboard, five Seabobs, dive gear with Bauer compressor, inflatable sailing catamaran, and kitesurfing equipment.
Works over the winter of 2024-2025 include extensive maintenance on the engines by MTU, comprising a full QL3 service, replacement of all exhaust manifolds, installation of three new turbochargers and the rebuild of one existing unit. The mechanical rebuild of the swim platform, new teak on the foredeck and sundeck, a full air conditioning service, and a superstructure repaint (the hull was repainted in 2019). Her steering rams, thrusters, stabilisers and propellers were all serviced during this period. Inside, all ceiling panels in the main saloon and guest cabins were replaced.
G3 is lying in Loano, Italy, for the winter and is available to view at short notice. Please don’t hesitate to get in touch for further information or to arrange a viewing.
