Skala or Perigialos is a safe harbor but subject to violent gusts in a strong meltemi (the Etesians). A new breakwater extension provides secure berthing for around 6-8 yachts med moored to the quay. Water and electricity points are installed and have now been connected (June 2013). Diesel can be ordered by telephone via a small truck from the nearby gasoline station.
It is also possible to moor stern to or alongside the outer quay but it is sometimes crowded and close to the ferries, and not at all protected from the Meltemi (the Etesians) (the Etesians). Alternatively, one or two yachts can anchor at the northern end of the bay, staying well clear of the anchors of yachts moored on the quay. Good holding in sand. The Hellenic Coast Guard is friendly, moderately helpful and their port fee is miniscule.
Skala is an attractive town and has a number of restaurants and a few stores with limited provisions. The gas station is not too far but up-hill.
Steno, as the local townspeople refer to it, divides Astypalaia into the eastern part known as the "Inner Island" and the western part known as the "Outer Island". The concrete road towards the "Inner Island" stretches past the successive beaches "Marmaria", "Steno", "Plakis" and the "Blue Limanaki" until it reaches Analypsi or Maltezana after a total of 9 Km.
