One-of-a-kind diving and sailing the BVI’s.

About Us

It’s all about you!!

Cuan Law, the most luxurious scuba diving liveaboard in the British Virgin Islands (BVI) has joined All Star Liveaboards liveaboard fleet as a member. As of September 2016, Annie and Duncan Muirhead, the owners of Cuan Law, have signed All Star Liveaboards to manage their dive industry marketing and reservations. The Muirheads will continue to provide the same high level of service underwater, on the dive deck and in the dining room which makes them a perfect complement to the team. 

The dive sites of the BVI can accommodate all levels of scuba divers — even beginners because the waters are especially calm. All guests will have the opportunity to dive the wreck RMS Rhone, one of the Caribbean’s best-preserved shipwrecks and the BVI’s newest wreck, the Kodiak Queen with a kraken on it. Cuan Law is unlike any other dive liveaboard in the Caribbean in its weekly schedule. There is no set number of daily dives: Guests can log as many as 19 dives during the week or as few as 15 if they would like to explore the islands. Plus, because these islands are so close together, the itinerary maximizes time for other adventures-kayaking, wakeboarding, Hobie cat sailing, and snorkeling. Most dive liveaboards spend the majority of the pre-flying no-dive day at port, whereas Cuan Law guests enjoy an afternoon at The Baths, the iconic grotto created by basalt boulders, flanked by white-sand beaches on Virgin Gorda.

The Cuan Law also operates several special trips each year to or from St Maarten with diving in Saba, Little Scrub Island off Anguilla & Sombrero Island.

The History of Cuan Law

Cuan Law is the largest sailing trimaran in the world, and she’s not like any other liveaboard dive boat you’ve encountered. Custom designed for luxury liveaboard diving and sailing by owner/designer Duncan Muirhead in 1988, and refit and redecorated on an annual basis, Cuan Law spans 105 feet in length and 44 feet in width. Two 103′ masts spread 5,200 square feet of sail over the massive deck. Her size and the triple hull design provide extreme stability, both at anchor and while underway. The Cuan Law crew will make you feel right at home the minute you step foot onboard.  Duncan and Annie started running sail & dive liveaboard cruises in the BVI with the sailing liveaboard catamaran Misty Law in 1970.

The Cuan Law has 10 large cabins with en-suite baths, each of which can be a configured as a queen bed or two twins.  In addition to the large sun deck and main salon, there is a large shaded alfresco deck where most meals are served.

BVI Shipwrecks

The British Virgin Islands (BVI) have a number of great shipwrecks like the RMS Rhone that sank in 1867, the Chikuzen and the most recent wreck the Kodiak Queen that has a large kraken on the deck.  There are a number of other wrecks besides these, including one site with 4 different wrecks.

The diving on the RHONE was fantastic.  It’s a reef in the shape of a wreck and we spend the entire day there and didn’t even see it all!


The crew is a lot of fun. They definitely take good care of you and the close proximity throughout the week means you really get to know them and the other guests.

The menu is quite varied and I can honestly say there was not a single item we didn’t like. We stayed at Peter Island after the trip where the food is supposed to be spectacular and it couldn’t hold a candle to Cuan Law.
