Turnkey and ready for immediate cruising, KARUNA features low engine hours and has been fully commissioned, optimized, and sea-tested. She is U.S.-registered and currently located in Key West.

KARUNA represents the cutting edge of modern yacht design--a long-range, diesel-hybrid-electric cruising multihull built for efficiency, comfort, and capability. She is well suited for transatlantic passages and equally comfortable as a liveaboard vessel, even in higher latitudes.

With a 29-foot beam, the LEEN 72 offers exceptional stability and volume. Her expansive interior and exterior living areas rival those of a 100-foot monohull, delivering approximately 1,378 square feet of usable space--an extraordinary feature in this class.

Built using a state-of-the-art composite construction process, KARUNA delivers exceptional efficiency with a range of up to 3,600 nautical miles--allowing for extended cruising with minimal refueling.

Powered by a 400HP Cummins diesel engine, she operates in seamless harmony with twin 20kW Bellmarine electric drives housed in the outer hulls. This advanced hybrid system enables quiet, emission-free maneuvering in port using electric pod drives, offering a smooth and near-silent experience.

KARUNA is a proven hybrid-electric multihull, supported by a large onboard generator that functions as an efficient range extender. Under electric power alone, she can reach speeds of up to 5 knots, while a typical cruising speed of 10 knots is achieved with remarkably low fuel consumption--approximately 2 liters per hour.

OWNER COMMENTS:

"I conceived KARUNA as a deeply personal project: a semi-custom built power trimaran created with a constant focus on balance, elegance, and uncompromising quality. Her name reflects the spirit in which she was imagined, a yacht designed to deliver serenity, pleasure, and freedom.

To ensure that every detail met the highest standards throughout the build process, I entrusted construction supervision to Loïc Blanken, a well-known international surveyor.

Owning and cruising KARUNA has been an exceptional experience. For six months, I explored the Bahamas aboard her, fully enjoying her remarkable comfort, versatility, seakeeping qualities, and the distinctive freedom of life on board. Today, despite my sincere attachment to her, my professional commitments no longer leave me the time she truly deserves. It is for this reason alone that I have reluctantly decided to offer her for sale".
