Hyperspeed Jet 4
High-speed catamaran ferry with vehicle deck · operated by Seajets
One of the newest additions to the Seajets fleet — a 22-year-old Austal catamaran that spent its whole career as Hellenic Seaways' Highspeed 4 before changing colours in mid-2026, still doing what it always did: a fast, no-frills run out to the Cyclades with plenty of car space.
Previously sailed as Highspeed 4.
