The marina dissolves into open water as the 8.6‑meter semi‑rigid slips past the breakwater. Salt wind tugs at jackets and the Atlantic spreads a low, rolling calm; small dorsal fins puncture the surface like punctuation marks. Guides scan with binoculars and you lean forward—dolphins are opportunistic performers, curious and quick, often riding bow waves or surfing the boat’s wake.
