Lampedusa and Agrigento yes and also Siracusa and Ragusa. Ragusa is often a more popular destination than Agrigento because although the sea journey is longer, it has a wilder coastline, much of which is unmonitored. North African hashish often comes through Ragusa too, for catania i imagine. I see these boats between donnalucata and cava d'aglia and was at sampieri beach last year on the day bodies washed up on the shore during a thunderstorm
