The two ports

Piraeus

Run by the Piraeus Port Authority (OLP). The Hydra passenger boats leave from Gate E8, with Hellenic Seaways' Aero catamarans boarding from Gate E9 — both about a 10-minute walk from the Piraeus metro station (Line 1 terminus). The port map pins E8 for the Saronic & Hydra fast boats.
