A low sun glints off glassy water as the boat eases away from the Oristano shore, the Sinis coastline sliding into view—granite headlands, pale sand, and the squat silhouette of Mal di Ventre. Guests trade the engine’s thrum for the hush of the sea; wetsuits, masks and fins become the tools of exploration as reefs and wrecks come into focus beneath the surface.
