Mustique, Saint Vincent and the Grenadines

Mustique, Saint Vincent and the Grenadines: Submarine Cable Landing Point

Mustique is a private island of approximately 2,470 hectares located in the Grenadines, a chain of islands in the West Indies forming part of Saint Vincent and the Grenadines. Despite its small and predominantly private character, the island hosts submarine cable infrastructure that connects it to the broader regional network. One submarine cable lands at Mustique, linking it to neighbouring island nations within the Eastern Caribbean.

The single cable landing at Mustique forms part of an inter-island corridor, extending connectivity between Saint Vincent and the Grenadines and Grenada. This positions Mustique as a node in the intra-Caribbean submarine cable network rather than a gateway for intercontinental traffic, serving the connectivity needs of the Grenadines island chain.

Cables Landing at Mustique

The Caribbean Regional Communications Infrastructure Program (CARCIP) is the sole submarine cable landing at Mustique. Spanning approximately 225 km, this cable reached ready-for-service status in 2019, though its status remains listed as draft. The CARCIP cable connects Mustique to other landing points within Saint Vincent and the Grenadines and to Grenada, establishing a regional inter-island link across the southern Eastern Caribbean.

Regional Context

Within Saint Vincent and the Grenadines, submarine cable infrastructure is distributed across seven landing points. Mustique shares the same single-cable profile as several other Grenadines landing points, including Bequia, Canouan, Chateaubelair, Owia, and Union Island, while the capital Kingstown stands apart as the most connected landing point in the country with three cables. Mustique's landing point is therefore characteristic of the outer-island nodes in the national submarine cable network, each served by a single connection rather than a converging hub.

Network Role

Mustique functions as a single-cable terminus within the inter-island submarine cable graph of Saint Vincent and the Grenadines. Through the CARCIP cable, it maintains a direct submarine connection to Grenada and to other points within Saint Vincent and the Grenadines, enabling intra-Grenadines and cross-border Eastern Caribbean connectivity. The cable's relatively short length of 225 km reflects the close geographic proximity of the islands it serves.

As one of six outer-island landing points in Saint Vincent and the Grenadines each hosting a single cable, Mustique represents the distributed model by which the national network extends connectivity beyond the main island to the smaller and more remote Grenadines. Its presence in the regional submarine cable graph ensures that even a small private island can participate in the Eastern Caribbean's shared digital infrastructure.
