2024 Leen Trimarans 72 "KARUNA" For Sale

2024 Leen Trimarans 72 for Sale: Spacious Power Catamaran in Key West, Florida

KARUNA, a 3-cabin/3-head + full crew quarters 2024 LEEN 72 power trimaran, is far more than a standard production yacht. She represents a highly specified, semi-custom hybrid platform shaped by an exceptional level of owner involvement, technical oversight, and continuous refinement.

Powered by a Cummins QSL9 400 HP main engine, twin 20 kW Bellmarine electric motors, and a 36 kWh lithium battery bank, KARUNA delivers a rare blend of long-range efficiency, quiet operation, and confident performance. Cruising comfortably at 10 knots while consuming approximately 5 gallons per hour, she offers true passage making capability with remarkably low operating costs and the capability of sailing over 3,500nm in the right conditions.

For buyers considering traditional expedition yachts such as Nordhavn and similar long-range platforms, KARUNA presents a compelling alternative that delivers comparable or better offshore capability, but with significantly greater fuel efficiency, enhanced stability from her trimaran platform, and a level of interior volume and livability that feels notably more open and modern.

With the presence of a large yacht and the practicality of a shallow-draft platform, KARUNA is equally at home exploring the Bahamas and the Caribbean as she is crossing oceans. Exceptionally maneuverable and easily handled by an owner couple, KARUNA offers the freedom of long-range cruising and the interior volume of a larger yacht, yet without the need for permanent crew.

Professionally maintained and continuously improved since new, KARUNA stands as one of the most distinctive and capable long-range cruising platforms available today.

For those seeking a more personal perspective, a note from KARUNA’s current owner is included at the end of this listing.

A LETTER FROM THE OWNER:

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 marine 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.
