Yes — every boat on charter.boats is insured by its operator; we require it. The policy covers the vessel for fire, collision and third-party liability. For damage it doesn't cover, your liability is usually limited to the security deposit. You can lower the deposit by adding the operator’s damage waiver.

Fuel isn't included — you return the tank full. Estimated from engine power: this boat's ~30 HP engine burns roughly 2.4 L/h while motoring, so a typical week (about 3 h a day, ~21 h) works out to roughly 50 L ≈ €98 at €1.95/L — scale it to your own plans.

Not if you add a skipper — this boat offers one, who holds the licence. Generally, though: Two crew with proof of competence are required — a skipper holding an ICC or national equivalent and a co-skipper who signs a declaration of sailing experience.

April–October, hot and dry with the strong northerly Meltemi wind peaking in July–August, especially across the Cyclades.
