The second yacht in the LM46 line of performance cruisers features a 7’7″ keel for top performance on the racecourse and a second head for increased comfort while either cruising or racing. Arcadia was launched in the spring of 2022. The yacht’s owner, an experienced racer, plans to enter the vessel in some of the most famous ocean races, including the 2022 edition of the Bermuda Race.

LM46 Hull No. 2, like every yacht in the LM46 series, is a high-performance, cold-molded sailing yacht that features the comfort and ambience of a wooden boat but delivering 10 knots of speed under both sail and power. The LM46 is a collaboration between Lyman-Morse founder Cabot Lyman, his son and company president Drew Lyman, and top Kiwi designer Kevin Dibley.

Whiskey Plank Installed

Construction is moving along quickly.  The crew recently celebrated the installation of the Whiskey Plank in Hull #2 of the LM46.  This second hull in the LM46 cold-molded performance sailboat series is scheduled to launch this summer.


LM46 Hull No. 2 features a powerful cruising rig with swept-back spreaders and 1,183 square feet of sail, including a squaretop main, that gives the LM46 an impressive turn of speed. Rolling out the optional asymmetrical spinnaker steps thing up a notch and lets the yacht hit speeds of 10 knots or more. When conditions are right, this yacht can click off 240 miles per day, while the wooden hull, 43’ waterline length, and comfortable displacement-length ratio of 133 allows for one-handed steering or easy steering by autopilot, no matter the weather. Equipped with a 7’7″ fin keel, LM46 Hull No. 2 will stand up to the most strenuous conditions whether racing offshore or family cruising along the coast.

Like everything else aboard the LM46, sail-handling is kept simple, efficient, and user-friendly: roller furling for the jib, a detachable staysail, and a mainsail furling system that is fast, easy, and effective. Following the French lead, we’re keeping weight out of the bow of the LM46 by using almost all anchor rode instead of chain. Quiet, easy — just like the LM46 itself.

And while LM46 Hull No. 2 will excel under sail, it can also deliver its crew just as swiftly under power, with an 80-horsepower Yanmar diesel powering the yacht at up to 10 knots.

Layout & Design

One word sums up the layout and design of the LM46: Soul. Too many boats built and bought today lack this key element, but by carefully considering every aspect of this new yacht – including the hull material itself – boatbuilders Cabot and Heidi Lyman and yacht designer Kevin Dibley have created a boat that is ingenious in its simplicity, efficiency, and performance.

The spacious cockpit features 6’5″ seats, ideal for accommodating guests or, when the weather is right, a night of sleeping under the stars. Twin helms offer unrivaled visibility, while the drop-down transom affords no-step access to and from the dinghy. All sail-handling is easily managed without ever leaving the cockpit.

Step below and enjoy a seat in the spacious salon and take in the V-groove overhead and combination of painted and bright-finished bulkheads and trim – you’ll instantly find yourself transported from your daily life to somewhere quieter, simpler, more elegant. The wraparound galley, designed using the lessons Cabot and Heidi learned during 16 years of living on their boats around the world, is as appropriate to preparing a three-course dinner as it is for mixing up a batch of evening cocktails. Aft, to port, a second head and wet locker provide easy access for guests or crewmembers coming off watch. The aft full berth to starboard makes for a welcoming guest cabin or, when offshore, the ideal sea berth.

Moving forward, to starboard you’ll find a separate head with vanity and a shower. The huge forepeak aboard LM46 Hull No. 2 includes a vee berth that converts into a centerline queen and storage for a weekend or a month’s worth of clothes and gear. Here, as everywhere aboard the LM46, you’ll be struck as much by what you see as what you don’t – we’ve included everything that you need and nothing that you don’t (watermaker, A/C, excess electronics).

The LM46 uses modern design and technology to improve upon the most sustainable building material ever created: Wood. Wooden boats 70 years old or more are still winning offshore and coastal races, sailing over many horizons, and, when necessary, are far easier to bring back to life after years of neglect. The Douglas Fir and Western Red Cedar planks that comprise the LM46’s nearly 1”-thick hull are sustainable, originating from sound growth- and forest-management plans and thousands of years of experience. Using the cold-molded building process results in a hull that delivers a quiet ride underway and is both flexible and incredibly strong. A layer of glass on the topsides increases durability and reduces maintenance. Wisely employing modern building materials and techniques and eliminating excess electronics allows us build a low-maintenance yacht that breaks the cycle of having to travel from boatyard to boatyard to keep a yacht in top condition – an ironic claim for the owner of a service yard to make, we’ll admit!

Lyman-Morse’s intelligent use of its Haas GR712 Computer Numerical Control (CNC) machine to cut planks, bulkheads, and joinery reduces costs for the hull and deck construction, but we have not thrown out the baby with the bathwater in the LM46. The cockpit, deck, and cabinhouse, often the site of water-infiltration in older wooden boats, feature a composite structure that keeps things bone-dry belowdecks. To use anything other than modern materials in these locations would be irresponsible.

Whenever possible, all items for the LM46 are built as modular units outside the boat – the same system used by wooden production boatbuilders half a century ago and somehow forgotten. We use such time-tested processes, combined with expert Maine shipwrights and high-tech tools such as lasers and 3D printers, to create a construction plan that is competitive with production boats but that yields a yacht that is meaningful and carefully constructed – a world apart from the fiberglass cookie-cutter boats that fill marinas and boat shows these days.

LM46: Putting the Real World in Perspective

The LM46 doesn’t deny the “real” world – it puts it in perspective.

More than 170,000 miles of sailing together, including a three-year circumnavigation with their three boys and numerous offshore races and trips to the Caribbean and the South Pacific, has shown Cabot and Heidi Lyman one thing: Boats have become too complicated. As the founders and owners of the world-renowned Lyman-Morse Boatbuilding Company for the past 42 years, they’ve built over 110 vessels, many of them equipped with watermakers and digital screens of all shapes and sizes. For many of us, all that gadgetry just distances us from why we started sailing in the first place: Reconnecting to a simpler way of life. Our day-to-day lives have become consumed with devices, passwords, and updates. Over time, our boats have tried to keep pace instead of providing an escape, a place where you can forget the world and simply enjoy. The LM46 changes that.

Spectacular in its simplicity, powerful in its performance, unparalleled in its quality. Contact us today and make the LM46 a member of your sailing family.
