Hydrofoils (also known as ?flying dolphins? in Greece), will begin operating between Samos and the Dodecanese islands on Tuesday.
The vessels will run every Tuesday, Wednesday and Friday.
They will sail from Pythagoreio on Samos to Kos and will stop at Patmos, Leros and Kalymnos.
Twice a week, they will also call in to port at Agathonisi.
The frequency of the crossings will be stepped up from June 16.
