Introducing THEA, an extraordinary vessel that is sure to impress even the most discerning buyers. With a full displacement, twin screw long keel design and a cold moulded timber hull comprised of 4 layers of 12mm planking, laid diagonally, the hull boasts an exceptional thickness of 48mm throughout. This, coupled with the close framing and diagonal planking, ensures unparalleled strength and durability.

Powered by twin Caterpillar 3408 engines, THEA can achieve a maximum speed of 13kts and a cruise speed of 10kts, while her 21,000 ltr fuel capacity ensures long-range capability. Four tastefully finished en-suite guest cabins, a Captains cabin and a further crew bunk cabin provide ample accommodation for all.

Originally built in 1979 in Junk Bay, Hong Kong by Kong & Halvorsen Marine & Engineering Company, THEA has a rich history that is sure to impress. Her builders, Joseph Kong (formerly GM of American Marine Co.) and Harvey Halvorsen, have a combined family history of boat building that dates back to 1887 in Norway and from 1924 in Australia. During World War II, the Halvorsen family built over 250 boats for active service for America, Netherlands, and Australia, and gained a well-deserved reputation for building reliable, strong, and well-designed boats.

After previous owners shipped her from Greece to Thailand, she underwent a complete rebuild from 2012 to 2014, during which time her hull was extended by approximately 2 metres. She then underwent yet another substantial refit in 2022, bringing her to A1 condition and ready for new adventures.
 

The current owner and his experienced crew have now completed the re-commissioning of THEA following her period of dormancy, and have made a number of improvements both mechanically, and cosmetically, and this is the yacht you see today. With the addition of a custom made pulpit, MY THEA is now registered as 30.08m with the intention of qualifying for the Thailand Charter License which is an option for any potential buyer.  
 

With its classic appearance, modern systems, and clever redundancy and flexibility, THEA is truly a labour of love for the current owners. We are thrilled to introduce you to this stunning motor yacht and invite you to embark on your own exciting journey with THEA.

THEA is fitted with two Caterpillar 3208 turbocharged diesel engines producing 525HP each. These engines were rebuilt in 2014 and currently show approximately 450hrs each. 

Sea water cooling is provided through sea chests.

The side decks to port and starboard are very safe and easy to pass. A new stainless steel handrail tops the teak capping rails on the main deck. Canvas drop covers remain in place to cover the decks and cap rails when unattended and the high bulwarks provide confidence. The original deckhead lights have been retained to maintain a sense of history.

THEA is fitted with two 35KW Lugger/John Deere powered Northern Lights generators. Each has local and remote starting. Both generators are mounted on airbag engine mounts to minimise vibration. The generators have low hours with approximately 2750hrs on both sides.

Both generators operate at low RPM (1200RPM) which makes them quiet and long life as well as powerful. 

The foredeck has storage lockers and a U shaped bench seat which is deep and protected. A custom table sits between the seats for dining and can also be lowered to form a daybed. Twin new Muir anchor windlasses are set forward with anchor and chain running from pockets as opposed to a bow roller. The bow area is wide thanks to the forward flare in the hull and a lattice work teak bow seat would be a perfect place to relax. The foredeck has fittings for a sunshade and sun umbrella. There are speakers connected to the vessels stereo system. 

A stainless steel pulpit was added to the bow in 2024 giving more space to the foredeck and the perfect position from which to grab that 'Instagram moment'. A nice feature that suits the vessel and increases its LOA. 

THEA is equipped with 2 x anchors which are approximately 150kg each. They are attached to 14mm studded galvanised chain and handled using 2 x Muir 4500 vertical windlasses. An anchor wash system uses either fresh, or salt water. 

Entering from the cockpit through double opening timber doors, one is welcomed into an informal lounge that is both wide and comfortable. It has the appearance of being a full beam salon whereas in fact there are generous side decks running both sides. Solid teak floors and teak veneer on all vertical surfaces are coupled with off white upholstered deckhead panels and teak louvre frames are used in place of curtains which is an excellent solution. These frames can be removed for full window views. Sofas and armchairs make for a relaxing atmosphere. A real ‘home away from home’. New artwork and sofa cushions were added in 2024 which has served to freshen up the interior.

Moving forward through the open ‘arched’ bulkhead that is also an outstanding feature that works very well, one finds the dining area. An extendable custom dining table can seat 8 persons and is made from a special Thai timber called ‘Khao Dam’. This black wood is complemented by black deckhead panels set in teak and with LED feature lights. Doors open to the deck from port and starboard side giving great access and cross ventilation in all conditions. Servery drawers and cabinets contain all galleyware and make this a perfect dining area, whether formal or informal. 

A sliding serving hatch and bar connects the dining room and the galley, and a day head is cleverly concealed and conveniently located port side forward. 

The galley is found on the portside running fore and aft and is a true chefs delight. It is fully fitted with appliances, including a commercial gas range, and has a full height fridge, dishwasher, microwave and oven. Corian counter tops are deep and run outboard of the galley below the opening windows. A double stainless sink and a rubbish solution that empties out via deck access show that much thought has gone into the functionality of the galley. Indirect lighting, and bright glass panels make this a wonderful space on board. 

Forward of the galley, taking the forepart of the boat from port to starboard is the utility area that leads to crew accommodation and features a chest freezer, icemaker, washing machine and dryer. 

THEA offers four unique cabins for guests, each with its own distinct layout and perspective. The private Master Cabin is located aft and can be accessed through its own companionway, leading from the salon. Upon entering the cabin, guests will find a small foyer that leads to a translucent glass panel separating it from the master bathroom. This feature allows diffused light to flow between the two spaces. The centrally positioned King-sized master bed faces forward and comes with a flat-screen TV on an electric lifter concealed at the foot of the bed. Guests will also find a leather-topped working desk and bookshelves to port, with drawers, cabinets, and wardrobes to starboard. A fridge is located in a cabinet to the port side.

The Master Cabin is full-beam and benefits from ample light and airflow provided by opening hull ports. It is tastefully decorated with teak floors, marble counter tops, and an upholstered bulkhead aft. The master head and shower is particularly spacious and light, thanks to the translucent ‘wall.’ The en-suite is finished with contrasting mosaic tiles, black marble floors, and a timber deckhead. It comes with a Vacuflush head, full shower stall, and Italian ‘Gessi’ brand high-rise faucet and washbasin.

The other two double guest cabins are located forward of midships and share a second companionway situated to starboard, leading from the dining room just aft of the main deck day head. This companionway leads to an athwartships corridor, providing access to the two guest cabins.

The starboard guest cabin is fore and aft and comes with an en-suite bathroom. This cabin is flexible, with one single berth opposite a long sofa that can be converted to be a twin cabin or a double. An occasional pullman berth could be fitted here. The cabin comes with a TV, working desk, and chair. Large hull ports provide ample light and ventilation. The cabin is finished in teak, with mosaic, marble, and contrasting colors in the en-suite head and shower.

The port guest cabin features a queen-size double berth, which is positioned athwartships and faces out to the hull windows. A Thai silk headboard is featured, and again a working desk and TV can be found. This cabin is larger than the portside cabin, and the en-suite head and shower are finished with glass panels and marble.

On the Upper Deck, located directly behind the wheelhouse, is the 4th guest cabin, which would ideally suit an owner/driver or anyone who enjoys a cabin with ultimate views and access to a private deck. This cabin features a Queen bed positioned to port facing aft, a particularly large en-suite bathroom, and hanging lockers and a working desk to starboard. Sliding timber doors open up to the deck and a large, sheltered seating area with a table for dining or conversion to a day bed. This deck is fully shaded by a fixed stainless steel bimini, and an open area is found further aft with space for the tender when underway or three aft-facing lounge chairs when the tender is deployed.

All cabins are tastefully finished with teak flooring and offer plenty of storage. Marble, glass, and granite have been used throughout the bathrooms, stairways, and galley.

The crew accommodation can be accessed by a crew companionway leading forward from the galley. The captain's double cabin is found in the bow, with a second twin cabin just aft. These cabins share a well-appointed head. These cabins are voluminous, with increased head height, ample light, and ventilation. Either of these cabins could easily be used as additional guest cabins.

Walking up from the dining area via a stairway to starboard is the wheelhouse. A full beam dash contains the navigational electronics and steering is either via a Joystick controlling the rudders, or the stylish ‘art deco’ hubless wheel. The twin helm seats are slimline in design and mounted on a customized bracket that allows both seats to turn and face the table and sofa situated behind. This allows for owner/driving dining in the wheehouse whilst underway, and in fact a dumb waiter leads her direct from the galley to assist. The viewing sofa is large and comfortable with superb views underway. Sliding side doors lead from the wheelhouse out to the wide Portuguese bridge surrounded by a solid teak cap rail. A locker in the centre of the Portuguese bridge has rudder, engine and thruster controls along with a Raymarine chartplotter, allowing the skipper to drive from outside. 

The vessel is built with a fully integrated hydraulic system. items on board using this system are Bow and Stern Thrusters, windlasses, all deck winches, both deck cranes, swim platform and stabilisers. 

A large pump is fitted to each engine which can be isolated. Adjustments to tension and alignment of the belts can be easily made. A 75 litre reservoir tank supplies fluid to the pumps.

The system is run from the engines when underway, but can also be operated using a 220V or 12v pump when alongside or at anchor. Cooling of the hydraulics is done via a dedicated cooler atop the seawater manifold.

The fuel system consists of two filling points on deck, port and starboard. Fuel travels directly to the six steel fuel tanks via a common line for a total capacity of 20,760ltrs. The fuel tanks were a new construction during the 2014 refit, and have adequate access for cleaning. There is no day tank, so fuel is drawn from any selected tank (or tanks) and directed to the Racor filters. There are four Racor 75-1000 filters arranged port and starboard in a dual filter arrangement. Emergency shut of valves are located externally at the entrance to the engine room. 

THEA also boats an Algae-X FPS-5000 Fuel polishing system that is plumbed into the supply and return manifolds so that fuel can be filtered from, and to, any tank.
