The eighteen-nautical-mile channel separating French St. Martin from British Anguilla has carried traders, smugglers, and islanders for three centuries, but modern ferry service between Marigot and Blowing Point began only in 1987. Before that crossing became routine, Anguillans relied on wooden sloops and improvised water taxis, a tradition that shaped the island's boat-building culture and left a fleet of hand-launched craft still visible along Road Bay and Sandy Ground. The st martin to anguilla catamaran route operates from Marigot Ferry Terminal seven days a week, with departures running every ninety minutes between 08:30 and 18:00. One-way fares begin at thirty dollars, excluding the mandatory departure taxes collected separately at both terminals. The crossing takes twenty-five to thirty-five minutes depending on sea state, and the catamarans themselves — twin-hulled aluminum vessels seating forty to sixty passengers — are built for stability rather than speed, their wide beams absorbing the Atlantic swells that funnel through the Anguilla Channel. Anguilla remains one of the few Caribbean destinations without an international commercial airport, a geographic constraint that has kept development measured and visitor numbers lower than neighboring islands. The ferry crossing is the primary arrival method for day-trippers and short-stay travelers, and the Marigot terminal functions as Anguilla's de facto front door. Immigration and customs are conducted on arrival at Blowing Point, where officers process passengers in a single-story concrete building fifty meters from the dock. The process is efficient but not instantaneous; thirty minutes for clearance is standard during morning arrivals. Once through, visitors enter an island of thirty-three beaches, most of them undeveloped and accessible by dirt tracks rather than paved roads. The population hovers near fifteen thousand, concentrated in The Valley and scattered coastal settlements. Tourism infrastructure is limited to boutique hotels and a handful of beach bars, and there are no traffic lights anywhere on the island. The catamaran crossing is also the foundation for a secondary market: sailing tours that depart from St. Martin and spend the day exploring Anguilla's southern coastline, stopping at offshore cays and reef sites before returning in the late afternoon. These st martin to anguilla catamaran tours typically include snorkeling gear, lunch, and open bar service, and they operate under a different regulatory framework than the scheduled ferry, requiring advance booking and operating from marina docks in Marigot, Simpson Bay, and Oyster Pond rather than the public ferry terminal. The distinction between ferry crossing and sailing tour is operational, not geographic — both cover the same water, but the latter adds leisure infrastructure and extends the itinerary beyond simple point-to-point transport.
