Margherita di Savóia is fronted at its NW end by a harbour contained within two moles, each extending about 450 m from the shore. The entrance between the moleheads is open NW and is 75 m wide. The harbour is frequented by fishing vessels. At the head of the harbour, a narrow channel between two small moles leads to a basin used by fishing boats. About 1 mile off the town in 11 to 13 m, mud; or farther offshore if desired, suitable only in fine weather.
