Owners Comments and Boat History
Cuan Law, one of the world’s largest sailing trimarans, was built in 1987 in Gananoque, Ontario, by Duncan and Annie Muirhead in collaboration with Hal McCarney. It followed two earlier vessels—Misty Law and Lammer Law—each named after peaks in the Scottish Misty Law mountain range. Continuing this tradition, Cuan Law was named through a guest contest, with the Gaelic term “Cuan” meaning “ocean” and “Law” meaning “mountain,” symbolizing the vessel’s powerful and serene presence at sea. Designed by Duncan Muirhead and constructed entirely from aluminum, Cuan Law features a schooner rig with equal height masts, 5,200 sq feet of sail along with twin Caterpillar engines, capable of cruising at 8–10 knots under power or 6–14 knots under sail.
Purpose-built as a luxury liveaboard, Cuan Law has offered all-inclusive sailing and diving charters in the British Virgin Islands for nearly 40 years. With accommodations for up to 20 guests in 10 private staterooms and a professional crew onboard, it delivers a unique experience centered around scuba diving, water activities, and time exploring the islands. Since its launch, Cuan Law has become an iconic presence in the region, known for its stability, spaciousness, and blend of adventure and relaxation on the water.
