First of all, many thanks to Hans Gsottbauer who managed to get hold of a draft timetable for Sebeco for 2022 and post it on social media. He also found that there is a new website which will show the timetable from next week (at the moment it only shows a picture of Yialos.
Assuming that the draft timetable is unaltered, there will be a daily service leaving Symi at 07:45 and 1530 for Rhodes and leaving Rhodes at 10:30 and 17:30 for Symi starting 27 April, up to 2 October. In high season there will be a third round trip in the middle of the day.
Once the definitive timetable appears, I’ll produce summary ferry times showing all operators, as we’re only otherwise waiting for SAOS Ferries, and they have only two sailings per week in each direction.
Some notes on booking:
There’s no need to book weeks or months in advance unless you feel making interest-free loans to Greek ferry companies is the best way to use your available funds. Greeks certainly don’t work this way. Now if you are travelling with a vehicle, it might be a good idea to book ahead as space can be limited, if you want a cabin on one of the overnight services to and from Athens/Piraeus the same applies. But just travelling locally in the Dodecanese (so Rhodes-Symi; Symi-Kos etc) you will be fine booking just a few days ahead, or even on the day itself (except in August when things can fill up fast). Blue Star and Dodekanisos Seaways have online booking systems and can accept tickets on mobile phones this year. We should know next week what Sebeco will do. Port ticket agents such as Symi Tours (support Symi businesses if you can) can also do online bookings. What I’d avoid is booking on line with companies who don’t operate ferries themselves and don’t have a physical office in any of the ports you’re using. Events of the past few years have shown that it can be difficult to get rebooked or refunded if you’re putting a third party between yourself and the ferry company, and that is one you can only contact by email and not by phone or in person. The official port agents on each island are well able to do this for you, as well as the ferry company itself.
Dodekanisos Seaways have a “frequent sailor” plan called Bonusways. You can join this on line before you book, and then use the membership number to get discounts right away. Blue Star have a slightly different system called Sea Smiles – here you buy the first ticket at the normal price, enter the details into a special kiosk onboard ship as you are sailing, and the kiosk issues a membership card you can use for discounts on future bookings. Both well worth joining, and you also accrue points that eventually entitle you to free travel – I got a free ticket to Kos from Dodekanisos Seaways in 2020.
