Kos is the natural launch pad for sailing the northern Dodecanese, and bareboat is the character of the place. The fleet is built around bareboat sailing yachts of roughly 30 to 54 feet, with notably strong catamaran availability for families and groups who want stability and space. Almost every charter begins at Kos Marina, a modern, full-service base in Kos Town beside the Old Town and below the Castle of the Knights, about 25 km and 25 to 30 minutes from Kos International Airport. The marina is home to a deep bench of operators — Istion, Kavas, Dream Yacht, Seafarer, Archon, Seven Sailing — with the old port nearby for crew embarkation. Skippered, cabin and flotilla charters are all straightforward here, and Kos-Bodrum gulet routes add a crewed blue-cruise option across the border.
The cruising is classic island-hopping with shelter never far away. A typical week is a northern loop of roughly 100 to 110 NM: Kos out to little Pserimos, on to Kalymnos (Pothia or Vathy), then Leros — whose Lakki harbour is one of the deepest natural harbours in the Med, fringed with Italian Art-Deco — before turquoise Lipsi and Patmos, with Skala, the Monastery of St John and the Cave of the Apocalypse. You return via Kalymnos and Pserimos. Stronger crews can push north-east to Levitha and Astypalea on more open passages, while to the south Nisyros offers a dormant volcano with a 3.8 km caldera and fumarolic craters, with Tilos, Symi and Rhodes beyond.
The defining wind is the Meltemi, a dry northerly that builds through the afternoon. Expect 15 to 25 knots, occasionally gusting toward 30 on exposed crossings, and short, steep Aegean chop in open water between islands. It is most persistent and strongest in July and August, making peak summer intermediate-to-advanced sailing best suited to experienced crews and careful route planning. June and September are far more relaxed and manageable. The Dodecanese around Kos is generously supplied with sheltered bays and harbours — Kalymnos, Leros and Lipsi among them — so downwind and protected legs are achievable with a little forethought.
The season runs roughly April to October. The sweet spots are June and September: warm water, lively but more moderate winds, and thinner crowds. July and August deliver the strongest Meltemi and the busiest harbours. Sea temperatures sit around 24 to 26 °C from June through August, peak warmest in September and hold near 23 to 25 °C into early October, while April and May leave the sea still cool. Choose your weeks by how much wind you want to work.
Kos Marina is a modern, well-equipped provisioning base right in town, so stocking up before you slip lines is easy. Bareboat charterers must hold a recognised qualification (ICC or equivalent); if you would rather not sail, a skippered yacht or crewed gulet is simple to arrange. One planning note: Greece-Turkey crossings to Bodrum or Datca need advance arrangement at booking so the yacht carries the correct cross-border paperwork and insurance — many bareboats are not permitted to leave Greek waters. You clear out of Greece at Kos, then in to Turkey at Bodrum with a Transit Log; visiting more than one Turkish port triggers a fee (around €150, scaled by tonnage), and clearance runs two to four hours each way. Stick to the core Dodecanese and the reward is unbroken: anchor below the smoking caldera of Nisyros, and the Aegean does the rest.
