The Aune 64 – A motor sailing trimaran designed for offshore voyaging with full livaboard capability.
The Aune 64 has an ultra light displacement main hull with a hull speed coefficient of 2.2. It has high buoyancy outer hulls (amas). When available space in the amas is combined with the volume of the central hull and the space provided by the bridge deck connecting the hulls, the spaciousness and accommodations of a light displacement monohull of almost twice the size is achieved.
Fitted with twin 200 hp diesels it is designed to cruise, with one engine operating, at 9-10 knots operating at the top of the torque curve, and up to 16-18 knots maxed out with both engines operating. Potentially it could cruise much faster under power with larger engines but an efficiency compromise is achieved with two engines of this size. At 10 plus knots using one engine at peak this boat can cruise 240 miles in 24 hours and about 400 miles using both engines.
Under sail there is even greater speed potential readily achieving double-digit speeds. Ocean passages with daily averages of 300 miles are easily attainable. Smooth stable motion whether on or off the wind in all but very rough conditions are to be expected under power or sail.
This is a true expedition boat suitable for any ocean conditions except ice. It’s designed to be comfortable in both rain drenched temperate areas or hot tropical climates due to light colored and fully insulated hulls and decks. There is excellent ventilation provided throughout including all seven inside living or working areas. Each of the five staterooms features a double berth, work station/desk and chair, full sized hanging locker, dresser drawers with a large private adjoining head and shower. There is high regard for personal space, privacy and comfort.
The concept driving this original design is an offshore cruising media studio capable of full production anywhere in the world with the ships crew, camera crew and editing crew enjoying living/cruising/working together. This design would also be ideal for use as a livaboard charter vessel for exploring, diving or other similar marine activities.
