Four yachts at 700,000 euros per week define ultra-luxury Caribbean charter in Mustique, with 75-metre and above vessels crewed by sixteen or more professionals anchored in Britannia Bay at one of the world most exclusive private islands. The Mustique Company oversees island access and anchorage management, and at this scale the vessel itself becomes the primary accommodation, with beach clubs, helipads, stabilised pools and spa suites all aboard. At 700,000 euros per week the advance provisioning allowance reaches around 210,000 euros, covering premium global provisioning, helicopter island transfers and a full operational budget for the week. The galley operates at fine-dining standard throughout the voyage, with provisions sourced globally before loading in Barbados. High season from December through April adds a 15 to 20 percent premium. Christmas and New Year weeks are priced as fixed holiday packages. From Britannia Bay, the full Grenadines arc to Grenada takes seven nights, leaving two nights for a northern extension to Bequia and St Lucia on a nine-night programme. Helicopter transfers allow guests to experience additional islands without repositioning the vessel, enabling a genuinely flexible Caribbean itinerary within the week.
