Four yachts at 800,000 euros per week anchor in Britannia Bay at Mustique aboard 80-metre vessels crewed by eighteen or more, combining the extreme end of Caribbean superyacht charter with the most private and exclusive of the Grenadines islands. The Mustique Company manages the bay, and at this scale the vessel is the primary luxury: multiple dining rooms, helipads, stabilised pools, spa suites and crew quarters that rival small boutique hotels. At 800,000 euros per week the advance provisioning allowance reaches around 240,000 euros, covering global provisioning loaded in Barbados, helicopter island transfers and a full operational budget for the week. Crew of eighteen or more manage every department continuously. High season from December through April adds a 15 to 20 percent premium, with Christmas and New Year at fixed holiday rates. From Britannia Bay, the full Grenadines arc to Grenada takes seven nights. A 10-night voyage adds a northern extension through Bequia, St Lucia, Martinique and Guadeloupe. Helicopter transfers allow guests to experience additional Grenadines islands and bays outside the vessel route, making the week genuinely flexible and personalised for each guest group.
