You step onto the pier as the estuary exhales — a soft brine-scented breath that carries gull calls and the distant clink of moorings. Frontino, a sturdy wooden boat built in 1957, rocks gently, its varnished planks warm from the sun. The skippers greet you with easy confidence; within minutes the boat slips out of the Alvor estuary and the town’s whitewashed roofs shrink behind a rim of salt-smoothed reeds.
