Sea Air Services (SAS-SXM)
High-speed ferry and air charter connections from Grand Case to neighboring islands.
Why Go
From its base in Grand Case on the French side, Sea Air Services bridges the gap between St. Martin and the surrounding islands through a combination of high-speed ferry and air charter options. Anguilla, St. Barths, and other nearby Caribbean destinations are reachable by sea or air — and SAS-SXM coordinates both, making it a single contact for multi-modal island-hopping.
The Experience
Sea Air Services combines sea and air transportation into one booking platform, which is unusual for the Caribbean inter-island market. The high-speed ferry services connect St. Martin to Anguilla and St. Barths — two popular day-trip destinations that are close enough to visit and return the same day. The air side of the business handles private and shared charters, helicopter transfers, and related bookings for destinations across the northeastern Caribbean. The Grand Case location, on the French side's culinary capital, puts the company close to the Grand Case airport (L'Espérance) and the small-aircraft infrastructure that serves St. Barths and Anguilla routes. For travelers who want to see multiple islands during their St. Martin stay, SAS-SXM provides the connective tissue — booking a morning ferry to Anguilla's beaches, an afternoon helicopter to St. Barths, or a charter to more distant islands becomes a single conversation rather than multiple separate arrangements.
What to Try
The Anguilla ferry is the most popular booking — a quick crossing for a day on some of the Caribbean's best beaches. St. Barths transfers by air or sea offer a taste of French luxury. Helicopter tours provide aerial views of the island that no ground tour can match.
Insider Tip
Book shared charters when traveling solo or as a couple — splitting the aircraft cost with other passengers makes private-caliber service affordable. The Grand Case office can help you build a multi-day island-hopping itinerary that mixes ferries and air charters.
