30m "Island Gypsy" yacht Thea back on market

The 30-metre Kong & Halvorsen yacht Thea is back on the market with Martin Holmes of Northrop & Johnson.

Constructed in 1979 by Kong & Halvorsen Marine & Engineering Company in Junk Bay, Hong Kong, S.A.R., China,, Thea (known as the “Island Gypsy”) has undergone extensive refits since her initial build. Designed by Harvey Halvorsen, who also completed the naval architecture, Thea is said to reflect the craftsmanship of the Halvorsen boat-building legacy.

Following a repaint in 2023, the yacht now boasts an oyster white exterior with a twin screw long keel design. Her cold-moulded timber hull, built from four layers of planking, achieves a thickness of 48mm throughout. Images also show solar panels fitted to her hardtop.

The yacht accommodates up to eight guests across four cabins. These include a master suite with a king-size bed, flatscreen TV and leather-topped desk, as well as a queen cabin and a convertible cabin with a Pullman berth. The upper deck suite features a queen bed and a private shaded deck with lounge chairs. Throughout the interior, teak flooring, marble, glass and granite have been used to create a sophisticated aesthetic.

The lounge area is spacious, with solid teak floors and off-white upholstered panels framed by removable teak elements that provide unobstructed views. New upholstery added in 2024 enhances the comfort of this area. 

Forward of the lounge, the dining area features an extendable table crafted from Thai timber known as “Khao Dam,” with direct access to the deck. A galley is located on the port side.

Thea’s wheelhouse spans the full beam and includes advanced navigation electronics. Steering options include a joystick or a distinctive “art deco” hubless wheel. The yacht’s stern has been extended to include a hydraulic swim platform and storage garage, while the foredeck features storage lockers, a U-shaped bench seat that converts to a daybed and twin Muir anchor windlasses.

Additional features include rainwater harvesting, a dedicated shower water supply and a dumb waiter connecting the galley to the wheelhouse.

Powered by twin Caterpillar engines, the yacht for sale has a cruising speed of 10 knots and a maximum speed of 14 knots.

Cruising Phuket, Thailand, Thea is asking $899,000.
