4 operators run this water, from 1 h 10 to 3 h 10 — a difference of 2 h 00 on the same crossing.
One row per operator and speed. Where a service is sold as fast and its average does not clear 45 km/h, the word appears in quotation marks — the boat is fast craft, the crossing is not.
If this crossing does not suit, these quays also reach Serifos without a change. It is the question a single-route page cannot answer about itself and an atlas can.

Our records for the Milos–Serifos crossing were read on 11 August 2026 and describe the network as it ran that week. We hold no month-by-month variation, so this page cannot tell you whether a crossing runs in February.
If you are travelling well outside August 2026, confirm with the operator before you plan around it.
No fares. The choice between SeaJets at 1 h 10 and the slowest at 3 h 10 is mostly a price decision, and we hold no prices for either.
No departure times. A weekly rate is a lower bound on how often the crossing runs — never a clock.
