Porto di Castellammare del Golfo is a small craft harbour fronting the N part of the town of Castellammare del Golfo which stands on a gentle slope rising from the sea to the foot of the mountains behind. Anchorage can be obtained off the port during offshore winds, W of Secca della Cernia (38°02′4N 12°52′8E), in depths of 12 m, good holding ground, or E of the shoal in depths of 16 m. In approaching the anchorages care should be taken to avoid tunny nets during the season (March to November) in which they are established. Designated anchorage berths, numbered B1 to B4, each having a radius of 750 m, have been established by the port authority. Anchorage is prohibited within these areas without prior authorisation from the Port Authority in Trapani, which controls this harbour.
