It is the Supramar PT 10 Freccia d'Oro, the first hydrofoil to enter commercial service
This is one of the earliest Supramar hydrofoils, the PT 10 (as can be seen in small print on the bow) named Freccia d'Oro. Unlike later Supramar hydrofoils, its hull was of wooden construction. Unfortunately this hydrofoil, which can be considered as the first hydrofoil to enter commercial service, no longer exists. However a nice article about it has been prepared by Tim Timoleon in one of the Issues of the free on-line magazine "Classic Fast Ferries".
