The Cuan Law is the largest sailing trimaran in the world, and she's not like any other live-aboard dive boat you've encountered. Custom designed for luxury live-aboard diving and sailing by owner/designer Duncan Muirhead in 1988, Cuan Law spans 105 feet in length and 44 feet in width. Two 110' masts spread 5,200 square feet of sail over the massive deck. Her size and the tri-hull design provide extreme stability, both at anchor and while underway. The seven crew members, headed up by Captain Gerry Matt, will make you feel right at home the minute you step foot onboard.
The name Cuan Law reflects owners and designers, Duncan and Annie Muirhead's Scots heritage. "Cuan" is the Scottish-Gaelic word for ocean and "Law" is Scottish for mountain. The images of Cuan Law's impressive size resembles the mountaintop rising from the ocean's surface. The Cuan Law was built in Canada and she and her sister ship Lammer Law in the Galapagos Islands are the world's largest sailing trimarans.
