154’ (46.94m) Admiral Superyacht STAR DIAMOND Now Asking $9.4M

Northrop & Johnson is excited to announce a significant $2,300,000 price reduction on the 154’ (46.94m) Admiral Marine superyacht STAR DIAMOND, now asking $9,400,000. With her recent 2024 refit and impressive charter history, STAR DIAMOND is one of the best-valued yachts on the market today.

Built in the U.S. to RINA Class standards and boasting a fresh nine-million-dollar upgrade, STAR DIAMOND combines timeless design with modern amenities and serious global cruising credentials. Her exceptional volume of 492 gross tons (unheard of in this size and price category) ensures spacious living areas for both guests and crew.

STAR DIAMOND received a full refit in 2024, including upgraded Quantum Zero Speed stabilizers with new control systems that enhance comfort and stability at sea. Her semi-displacement hull delivers a fast cruising speed of 14 knots and a top speed of 18 knots, making her capable of making up time when it matters most. Designed by Donald Starkey, her interior exudes the casual sophistication of a beach house, warmed by Bubinga wood and natural light flooding through oversized windows.

She accommodates up to 10 guests across five versatile staterooms, including two convertible cabins that can transform into either twins or king berths and a flexible sliding wall configuration that allows for the creation of a spacious full-beam VIP suite—ideal for families or groups seeking more flexibility. The full-beam master suite has his-and-her bathrooms, a Jacuzzi tub, and an owner’s lounge with reading chairs, a desk, and an entertainment area.

Her sundeck is widely considered the best in her class, rivaling even yachts up to 185 feet. The expansive layout includes twin U-shaped bars, a Jacuzzi, generous lounge areas, a barbecue and circular teak cocktail tables. The space is an entertainer’s dream, with 360-degree views shaded by triangular sun canopies. A circular interior staircase provides seamless access between decks.

STAR DIAMOND’s structural upgrades in 2023 and 2024 included significant work to her bow and keel, improving her ride quality and eliminating flexing and creaking. She features a large garage for toys, spares and equipment, ensuring clean, clutter-free decks and easy operations for the crew.

Her expansive aft deck stores a 19′ AB tender and four Waverunners, with protected hatches for Jet Ski storage and easy deployment. The yacht also includes a wide swim platform with a teak deck and hydraulic opening transom door, ideal for effortless access to the water and fun-filled afternoons. With a proven charter history, STAR DIAMOND can cover her annual running costs under the right ownership and management.

Whether you’re seeking a charter powerhouse, a world-class cruiser, or a turn-key opportunity with unbeatable value, STAR DIAMOND is ready to impress and available now.
