2012 78 Custom TransOcean Powercat IETA is one-of-a-kind: only a custom-built vessel could combine such serenity & luxury with the utmost in ruggedness and durability. Having crossed the Pacific, she is prepared for long passages. Her unique blade technology & wave-splitting fins allow her to skate across the water. In addition, her superstructure was specifically designed so that in certain wind conditions additional speed can be gained to increase efficiency. An extremely green boat, she is fully powered by solar and her economical John Deere diesels sip fuel. 

While she is a capable, long-haul cruiser, she offers impressive style and comfort. French mahogany and bamboo interiors are warm and welcoming with the hand-finished appeal of a classic yacht. Large windows keep each space airy and bright. The layout is spacious and serene. All of the finishes show a spectacular attention to detail. Every space is utilized to its maximum to curate comfort, enjoyment, accessibility and efficiency. 

With the ideal combination of strength and beauty, IETA is calling your name.

She is currently gleaming with a brand new paint job in a custom shade of white. She has just had a new bottom job including being fully sanded, epoxy reapplied where necessary and antifouled.

The super-structure is designed for aerodynamic positivity. At wind of over 12 knots, and anywhere from 10 degrees onwards off the nose, IETA can self-produce up to 1 knot of additional speed, (or when the wind is to beam). Her 8 foot topsides keep the deck dry in most conditions.

The hull is a full epoxy sandwich construction – 96% AIREX Foam Epoxy Glass, 3% Kevlar, 1% Carbon. The design incorporates crash boxes (bow and stern) and has foamed compartments in the bow “blades” to withstand collision with a stationery object at 14 knots. IETA has more real buoyancy than weight, making her non-submersible. She also features a series of 12 sealed watertight compartments as an additional safety measure.

Her hulls are two to three times longer than her width. The length-to-width ratio optimizes performance. The build was routinely inspected by BUREAU VERITAS and IETA carries a full Certificate of Conformity. She is sold with a comprehensive out of water Marine Survey completed January 2023.

She has sailed in big seas with ease and completed several long passages in excess of 900 nm including a 3500 nm 29 day passage from French Polynesia to Mexico.

Engine Rooms

The port and starboard engine rooms are a masterpiece of engineering and ergonomics, with a headroom of 6’ 10. Accessibility has been prioritized and the engines can actually be hoisted up to be worked on at eye level. They can be reached at all times and in all sea conditions. 

The port engine room / workshop has a bench with vice, and a comprehensive array of tools. A very large stock of spare parts is carried on board, including a new propeller. The combination of spares and tools allows for self-sufficiency in remote areas away from civilization.

The engines are extremely economical. Cruising at 6-8 knots she has a range of 4300-7000 nautical miles.

The engine room has been thoroughly sound-proofed to 63 Db in the salon and 40 Db in the pilothouse at 11 knots.

Ventilation & Heating

IETA has been carefully designed to allow for maximum air efficiency and ventilation – the complete air volume of the vessel is renewed every 3 minutes. Natural ventilation is achieved through a system of fully integrated dorade boxes installed on the fore deck which provide additional throughflow to the hull cabins. During heavy weather, ventilation is attained via vents in the superstructure on the wheelhouse and living area level. Louvers over the windows mid ship are set at negative angles and minimise heat penetration whilst preserving full visibility. The hull is also fully insulated. Additional cooling is provided by two portable 230-volt model KYR-25CO/AG-H (2700 watts) air conditioning units.

Heating is provided primarily by solar energy. 2 x 12,000 BTU diesel water boilers provide hot water and feed a central heating system in all internal rooms, controlled by separate thermostats. The wheelhouse has a pulsed air heating system with 4 windscreen outlets.

Your team delivered on every mark. You’ve got an amazing broker in Mark Wattrus and I’m confident you will have continued success moving forward together. He was available 24/7 whenever I had questions. We had a great initial visit on the boat and his marketing plan and photos were superb

— Jimmy

I bought a yacht that I had never seen. I did this because I trusted my broker Andrew Holland. It was not an easy job for Andrew, as I am an experienced boat builder and owner of previous yachts, but work in West Africa. Imagine how hard it was to communicate what I was looking for. Andrew came up with exactly what I wanted. He dealt with time delays, all my questions at odd hours, and was there for the survey. He reported honestly and professionally. After buying the yacht, I arrived at the boat on a Sunday night, after dark, after travelling from West Africa to the Caribbean, and found it was better than expected. He never pulled punches and made me aware of shortfalls. I expected to spend my one month leave working on the boat, but actually spent less than one week, and was able to spend 3 weeks sailing – wonderful bonus.

Thank you Andrew for putting up with all my questions, all my worries and all my crazy out of the time zone concerns – you were totally professional, but also I know that if and when we meet up, it will be like a friend finally meeting. You are always welcome on Aseka.

Outstanding company with professional subject matter experts. If I were to buy or sell cruising sailboat, particularly a catamaran, Andrew would be my go to broker.

— JT

I have been sailing since I was a child and attended Massachusetts Maritime Academy. But when my wife and I began the process of purchasing an ocean cruising/racing catamaran, I realized that this is a world unto itself. Obviously, we needed to find someone knowledgeable to help us make an informed decision. More importantly, we needed someone honest and willing to put our interests before his or her own. I was lucky to work with Phil Berman at The Multihull Company. He repeatedly shunned the fast buck, choosing instead to work the long road to connect us with the “perfect boat”. I would be glad to recommend Phil and his company to anyone planning to purchase or sell a performance sailing machine.

— Eric Boutiette

Andrew Hodgdon was our broker when we bought our 2018 Lagoon 450F in Antigua in April 2922. He provided great service and was very attentive to our needs. We would highly recommend Andrew and the Multihull Company.
