Green Sailing and Diving in the BVI

Biggest Trimaran of the world

Biggest Trimaran of the world

High-class dive adventures on the biggest Trimaran on earth.

CUAN LAW is largest Trimaran in the world, and with probably the smallest carbon footprint per guest of any large liveaboard. Think of our boat as a luxury country inn with a sporting flavor that moves around these sheltered seas in the beautiful green British Virgin Islands. The amenities, food and attentive friendly service from the seven crew looking after just twenty pampered guests, are what you would expect from a fine, family run establishment. The three hulls of the trimaran result in excellent stability, at sea and at anchor, and the towering mountains of white canvas are an awesome sight and speed the ship along without burning fuel. Of course, the small twin diesels give the ship good speed, 10Kts, when the wind dies.

The sporting flavor is primarily SCUBA, but with many activities for the non-diver such as Hobie Cats, kayaks, water skis, wake and knee boards, snorkeling, island exploration and beach barbecues. Perhaps you would just like reading, rest and relaxation with maybe a massage in our on board spa.

The accommodation is really welcoming in light, airy staterooms, each for two people, twin or double, each with private bathroom, air conditioned, or with natural ventilation from large opening hatches and windows. CUAN LAW carries just twenty guests in her 110 foot length. Our long years of experience, forty years for our company, our friendly caring crews and our enviable reputation, result in heavy bookings and a very high repeat rate. So book early and come and enjoy!

You can book as a group of up to twenty for whole or partial boat, or individuals and couples can book a berth or by the cabin.
