At 500,000 euros per week, the Turks and Caicos charter fleet represents some of the most technically advanced private vessels afloat. Yachts in this range measure 80 to 90 metres, carry a crew of 18 to 22, and are equipped with systems more usually found on research or expedition vessels: dynamic positioning, full dive chambers on some models, submersibles, and stabiliser fins that eliminate roll at anchor. The Turks and Caicos suits this class of yacht precisely because its combination of shallow bank and deep ocean wall diving demands a vessel with both shallow draft capability and open-ocean range. The protected waters of the Caicos Bank, crossed in a single morning passage, give way to the vertical reef face off Grand Turk where the ocean floor drops 2,000 metres within 300 metres of the surface. At this level the advance provisioning allowance approaches 150,000 euros per week. The crew manages a vessel that is, in practical terms, a floating luxury hotel, with the executive chef responsible for a food and beverage operation of restaurant complexity. Most yachts in the 500,000 euro weekly range offer a range that extends to the Dominican Republic, Puerto Rico and the broader Greater Antilles within the same charter period, should the guests wish to extend the itinerary beyond the Turks and Caicos. The sailing season for the Turks group runs year-round, though November through April offers the most settled conditions and the best diving visibility, which regularly exceeds 40 metres on the outer walls.
