At 600,000 euros per week, the Tobago Cays Marine Park and the southern Grenadines become the setting for a charter aboard a mega superyacht of 90 to 100 metres. These are vessels where the scale of the interior, the depth of the crew and the range of on-board facilities represent the current frontier of private maritime operation. The marine park’s Horseshoe Reef and turtle grounds are accessed by tender from an outer anchorage that accommodates yachts of this displacement. Mayreau’s Salt Whistle Bay, Petit St Vincent and Palm Island round out a southern Grenadines itinerary of sustained variety. Union Island provides the operational base for the southern part of the chain. The advance provisioning allowance at 600,000 euros per week reaches approximately 180,000 euros, covering extended fuel consumption, fine dining provisioning and private marina fees. Peak season from December through April is typically committed a year or more in advance on vessels at this level. The experience places the Caribbean’s most celebrated marine park alongside on-board facilities that match or exceed any land-based resort.
