Not for sale or charter to U.S. residents while in U.S. waters.

This graceful Bill Tripp design was built by the renowned shipyard Marten Yachts in New Zealand. LADY K is a testament to their mastery in crafting both opulent cruising yachts and high-performance racing vessels, including contenders for the America's Cup. Combining strength with minimal weight, LADY K stands as a light, swift and comfortable sailing yacht.

Her carbon fiber main and mizzen masts, crafted by Martin Marine / Southern Spars were equipped with ECSix standing rigging in 2021, showcasing a substantial improvement, halving the original rigging's weight. The boom furling system ensures efficient sail control and effortless reefing, while the low-aspect ketch rig provides versatility in sail options.

With a minimum draft of 6’8”, the brilliant lifting keel feature allows LADY K into the most appealing and coveted harbors and anchorages worldwide. 

Inside, LADY K boasts a raised salon design featuring an abundance of glass that floods the interior with natural light. A forward-facing navigation and helm station provide commanding views, while the raised dinette is perfect for everything from morning coffee to cocktails, lunch, or simply savoring the views. To port, an additional settee invites relaxation. The lower salon and galley, centrally located and illuminated by overhead glass, comfortably accommodates six guests. Entertainment options abound with Apple TV and Bose surround sound. The galley, thoughtfully designed in an L shape, is highly efficient.

LADY K's layout offers four guest cabins and a crew cabin for two, complete with upper and lower berths and a private head. Aft, three guest cabins await. The owner's cabin is full-beam and features a centerline queen berth, a small settee, and separate head and shower compartments. The first guest cabin offers side-by-side twin berths with access to a head and shower compartment. The second guest cabin features upper and lower berths, while the third guest cabin is forward of the galley, boasting a double berth and private head and shower.

LADY K's exterior, designed by Bill Tripp, radiates timeless beauty with classic proportions and graceful sheer lines. Her profile is as elegant as it is functional. Dual staircases provide easy access to the swim step, where garage space is available for water toys. The cockpit, equipped with dual helms and a centerline table, offers excellent protection while ensuring the skipper maintains clear sightlines. LADY K's exterior decks are engineered for practicality and ease of maintenance. With no exterior woodwork, there's no need for varnish or teak decks. The deck coatings remain cool underfoot and ensure safety. Her side decks are wide and uncluttered and the unobtrusive tender storage behind the mizzen allows for quick and effortless launch and retrieval.

In every aspect, from her build to her interior comfort and exterior design, LADY K embodies smooth sailing and functionality, making her the ideal vessel for discerning sailors seeking a memorable yachting experience.

Full Details


LADY K has taken her owners approximately 220,000 miles through every ocean on the planet in comfort and safety, routinely covering 200 miles per day and frequently far more. Her lifting keel allows brilliant upwind performance and, when retracted, allows access to the most desirable harbors and anchorages.  

There is no exterior teak. Maintenance has been easy but scrupulous. LADY K shows no evidence of her miles or age. Redundancy is a theme: autopilots, radars, plotters and spares. This is a sailing yacht that is ready to circumnavigate again, needing only provisions.  

Designer's notes:

This 77 ft. (23.4m) fully custom yacht is designed for unlimited blue water cruising, with an emphasis on passages and autonomy in remote places such as the Pacific atolls. Lady K is one of numerous “off-road” boats” by Tripp Design and is still in the hands of her original owner.

LADY K is in pristine condition, benefitting from a comprehensive re-fit at Pendennis Shipyard in 2015/16 and a second thorough yard period in 2020. 

She is light displacement design with fully cored Aramid/E-glass construction. Kevlar was chosen for maximal impact strength. For ease of maintenance while traversing the globe, Lady K does not have teak decks and any exterior woodwork. She does, however, have an engine room with standing headroom and a workbench as well as a layout that allows access and service to all equipment.

Being purpose built, she has many features to support distance sailing and easy handling by a small crew. The centered cockpit is very well protected, with shelter behind the raised pilot house. She is particularly good for sailing at night or under adverse conditions with all winches, furlers and sail functions controlled from the cockpit. The cockpit is directly accessed from the Pilot House and the boat can be handled from the inside steering station.

The absence of any backstays on the swept spreader ketch rig allows full roach main and mizzen sails. These sails are easy to control, and reef very well with the furling boom systems. As a ketch, all the sailing loads are lower than a sloop and the boat heels less. The boat is very fast with eased sheets, reaching and running with the ability to fly numerous sail combinations safely and easily.

The jet tender lives in a well on the large aft deck for easy deployment and allows the transom garage to be used for storage of all necessary gear and toys. The transom steps allow safe and easy access to the boat by tender, without having to deploy a transom door.

The centerpiece of the design is the upper salon and helm station which are raised above the engine space. Extensive curved (chemically strengthened and laminated) glass provides panoramic views. Below deck, the boat has been thoughtfully laid out for blue water cruising. Aft of the engine space are two guest cabins, a laundry space and a spacious owner’s stateroom. Forward is an open galley and lower salon with abundant seating. Fully forward there is an office desk as well as an additional guest cabin and crew quarters. Here too the boat has been beautifully maintained, and her gleaming woodwork belies her age. Under the care of this experienced owner, Lady K has truly only improved since her launching…
