Aegean Sea Lines

24 crossings between 7 ports . On 0 they are the only operator on the water; on 0 they are the quickest of several; on 18 a rival is faster.

Three things the timetable does not say

0 of 3 services marketed as fast actually average over 45 km/h door to door. The other 3 are fast craft on routes with enough calls that the average comes out at conventional speed.
0% alone of their network has no rival at all. On those 0 crossings the question is not who is quicker — it is whether you sail. A comparison site showing one result is not showing you a choice.
18 beaten crossings where another operator is quicker on the same water. Their own site cannot tell you this, and a booking engine sorted by price will not.
6 untimed crossings carry no duration anywhere we can source. They are counted in the 24 and left blank in the bars.

Where they are beaten

18 crossings where a rival is faster or the two are level. This is the section an operator would never publish.

Which months they sail

Season not heldwe can say when we looked, not which months run

Our records for Aegean Sea Lines crossings 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.

Where our records stop

No fares. Every comparison on this page is time and frequency only, and the fast-versus-conventional decision is mostly a price decision.

No departure times. 0 of 24 crossings carry a weekly rate; none carry a clock.

No vessels. We hold a fast/conventional class and no ship names.
