bvi-sailing-vacation Duncan and Annie Muirhead started out in the live aboard sailing and diving tourism business with the launch of their first boat, the Misty Law in late 1969. They ran this boat themselves for many years doing five Atlantic crossings as they spent the summers in Greece and the winters in the BVI. Keen divers themselves in the early seventies they realized that diving was going to become a main stream sport, so they stopped their European adventures and pioneered the concept of living aboard a diving boat and they settled in the BVI. At that time, there was only one other pioneer in the whole world and that was Paul Humann in the Caymans.

The demand for this type of diving tourism exploded so Annie and Duncan got together with a charterer, Hal McCarney who built boats. In 1978 they created their first effort, the Lammer Law, designed by Duncan and built by Hal. But Annie needed more beds so in 1988 the second aluminum trimaran, the Cuan Law was built. After some changes in demand the Lammer Law was moved to the Galapagos, the Misty Law was sold along another trimaran they owned and had also operated in the BVI.

Annie and Duncan have believed in a simple philosophy. Take good young people and train them to work together in a friendly atmosphere but never forgetting that good service is paramount. That has been a great pleasure in their lives - to see young people develop their characters so well. Also to provide a boat for their guests that mimics a small luxury hotel with lots of activities to try. Treat non diving companions as equally as important as divers. Add really good food and the latest in a long line of amazing chefs certainly provides that!

In 2017 Annie and Duncan retired but their legacy lives on and both are very free with advice to daughter Sasha and manager Kim who has almost grown up with the company having been around for 30 years and counting. Both do a fabulous job.

The heart of any ship is its crew and this is even more important in a Floating Hotel. All our crew are very energetic and fun loving with a great service attitude. They have their individual specialties but all pitch in as a team and cover for each other. We normally carry a crew of seven: Captain, Chef, Engineer, First Diver, Second Diver, and two Stewards or Stewardesses.


Because of crew rotation, your crew will be from the following.



Captain Scott over many years has done everything and every job on the Cuan Law except Chef. We owe him a huge dept of gratitude as he has been the foundation stone of the crew. He has trained up dozens of our crew over the years. Scott started off as steward on board and then, after getting his Divemaster rating, he led many dives in addition to his work as steward. Scott still loves to dive and will certainly do some dives with you whilst on board. He then moved on to Engineer as he had always had a great interest in, and aptitude for, the ship's machinery and equipment. He has fixed numerous problems, installed much new equipment and machinery and done many upgrades. He still likes to mess around below decks playing with machines! After a few years as Engineer and then First Mate, we promoted him to Captain and added the job later of Captain Trainer. Scott has done many, many charters as Captain, has as much knowledge as Trimarine’s founder Duncan, and really understands "The Cuan Law Way". He has a great sense of humor and is very fun-loving, and he runs a well organized and motivated team. Years ago he married our then Chef, Kellie, whom many of our past guests will remember and future guests might get to meet as she and Scott continue to fill in as relief crew. Scott’s sister, Kim, is our Operations Manager.



Kellie grew up on the move, but never beyond the Florida border until after she graduated university with her degree in Studio Art. From there she went on to live and work with other artists in New York, France, and finally the British Virgin Islands, with interspersed trips to India, Southeast Asia, and Central America. Her love for adventure (and very little convincing from Captain Scott) landed her aboard Cuan Law back in 2009, where she has worked as both stewardess and chef. She’s now part of the Kellie and Scott relief crew and training team, finding joy in sharing tales of her own adventures aboard to both new crew and guest alike, including some fantastic down island trips with Annie & Duncan! When not on Cuan, she most likely has her hands covered in clay while she runs her pottery business, Sugar Sand Pottery, back in her Florida home with Scott.


Operations Manager

A few years after graduating from college when she decided to take some time to start traveling Kim first joined Trimarine the same year that Cuan Law was completed - 1988! She worked on board Lammer Law initially as stewardess and then worked on Cuan Law as relief chef on and off for several years interspersed with some great trips including 3 years in Japan, before making the BVI her permanent home in 1994. Her BVI adventures include working with small businesses, building a vacation villa and running the guest house style villa Annie & Duncan Muirhead owned, Serendipity House, until its sale in 2014. Her move to the Trimarine office in 2000 started off as a part time thing, but as time has passed and most recently with the impact of Hurricanes Irma and Maria in September 2017 Kim has taken on more responsibility. It is most likely that you’ll reach her when you email or call us!


Dive Instructor

Reka Lukacs is a Hungarian girl from Transylvania, Romania who joined the Cuan Law early in 2018. She began her travels as an au pair in England where she learned English and ever since she got comfortable speaking it she just can’t stop traveling! She lived in Mexico where she was mesmerized by the beauty and magic of the underwater world so she became a diver. After that she continued her journey to Thailand where she spent a lot of time guiding the shark watch trips and got passionate about underwater photography. She got to experience a bit of Australia as well before riding the waves on a rigid inflatable boat to the dive sites of Mozambique. She already enjoys the shore hike/walks around the smaller islands of the BVI and exploring the big rocks at The Baths on Virgin Gorda. She is a fun loving, talkative girl who is all smiles and laughs and ready for games at any time :)

Bio coming soon!



Lucas has been sailing since he was just 13 years old, initially as a hobby. His experiences include cruising and boating in the North Sea, Mediterranean, Baltic, Adriatic, English Channel, Atlantic Ocean, Caribbean Sea and the Pacific Coast of Mexico! In 2015 he made a life-changing decision to abandon the career in engineering that he had pursued in London, to become a professional sailor. He hasn’t had a single regret since. One of his jobs took him from Greece, around the Med then across the Atlantic to Cuba, and then via Mexico to The Bahamas. All of this was on a sailing catamaran which was fitted out as a small 8 passenger liveaboard dive boat. That’s where he dived for the first time and – just like with sailing – he was hooked from day one. Great customer service and a sharp focus on safety, as well as flexibility and professionalism are what you will experience while on board with Lucas. He will take you around the best spots in the BVI and make sure that you return home, with lot of great memories, stories and photos to share with your friends.



Dan joined us in July of 2021 from London, England with Cuan Law being his first role in the charter industry. After graduating university with a Masters Degree, Dan took up the hobby of sailing and has since gone on to achieve his Yachtmaster Offshore Captain’s license alongside various other marine engineering qualifications. He is a keen traveller and has spend 2 years teaching Maths & Science in Thailand whilst travelling around Asia including places such as Japan, Vietnam and Mount Everest Base Camp in Nepal. Dan is also interested in Diving and is hoping to achieve his Dive Master qualification during his time onboard Cuan Law so expect to see him getting in the water with you when he can. Dan is always filled with a random pieces of knowledge and would make a great addition to any pub quiz team.



All the way from sunny South Africa, Amber has joined our crew with an extensive customer service background. Amber started out in the hospitality industry, running and owning a chain of restaurants back home. Another one of her passions is trading cryptocurrencies and her love of trading and passion for people led to the creation of her own online training company, teaching others to trade cryptocurrencies as well. Looking for a new and exciting experience and a way to dive back into the hospitality industry, Amber packed her bags and travelled half way across the world to join our team as a stewardess. Although new to the boating industry, Amber welcomes new challenges and faces every situation with a bright and positive can-do attitude. And as for her cocktails...she's got your holiday vibes sorted!
