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 technical upgrades 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 fin stabilizers, and in 2024, her steering rams, thrusters, stabilizers, propellers, and swim platform were all overhauled or serviced to ensure reliable operation.

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 for a more connected indoor–outdoor experience. The galley is fully equipped with Miele and Hoshizaki appliances, and a dumbwaiter system supports smooth service. The skylounge, updated in 2022, opens onto the bridge deck aft, offering a flexible space for entertaining.

G3 accommodates up to 12 guests in five cabins, with room for nine crew. The full-beam master suite is located forward on the main deck and includes floor-to-ceiling windows, a generous en-suite, and a private office 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. Crew are housed in four cabins, including a bridge deck captain’s cabin.

The sundeck is the centerpiece of G3, featuring a Jacuzzi encircled by sunpads and a full outdoor cinema system. The bridge deck aft is arranged for shaded alfresco dining, and the main aft deck flows seamlessly from the interior. 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. The foredeck is configured for tender and toy storage, carrying a Williams Sportjet 375, four Seadoo Spark Jet Skis, two eFoils, a Radinn jet surfboard, five Seabobs, and more—including dive gear with Bauer compressor, inflatable sailing catamaran, and kitesurfing equipment.
