Not far away from the lighthouse on St. John (Sveti Ivan), near the coast of Rovinj, at a depth of 30-35 metres lies Maona, a small freight ship with a length of 40 m that offers relatively easy dive, under conditions of good visibility. On the bottom where lies the stern of the ship, it is possible see many lobsters and rockfishes. Like all artificial walls, the ship attracts large numbers of small fish, and thanks to its proximity to the coast, is visited by numerous divers in the tourist season.
