Grivalia 1

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, except where the operator's terms say otherwise. Operator terms: The owner insures the vessel at their own expense as required by legislation for professional pleasure yachts. Travel insurance, cancellation/curtailment insurance and charterer's liability insurance are highly recommended and must be arranged by the charterer.

Fuel isn't included, and on a powerboat it's the biggest variable cost. Estimated from engine power: at a typical planing cruise this boat's 435 HP engine burns roughly 65 L/h — about €127 an hour at €1.95/L. It depends heavily on speed: easing off the throttle cuts it sharply, running flat out raises it. Plan your fuel around the hours and speed you expect to cruise.

Not personally — a skipper is included with this boat and 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.

Pets are only allowed with the owner's prior approval, so please ask us before you book and we'll confirm for your trip.

If your planned route can't be sailed for safety or weather reasons, we'll first offer an alternative excursion. If that isn't possible or you don't want it, we'll offer another date, subject to availability. If neither works, the payment is refunded minus a small administration fee.

Smoking is not allowed inside the yacht, and illegal drugs and weapons are strictly forbidden and can end the charter immediately with no refund. The captain can also stop any activity that puts people or the yacht at risk.

On daily charters, one cabin and one WC are available to you and your guests unless we agree otherwise. Children must be supervised by an adult in your group at all times. Please treat the toilets and showers gently, as blockages from items like toilet paper or sand are charged to you.

Yes, with conditions. Jet ski use needs a valid licence and the captain supervises and can reduce the speed or refuse use if he judges it unsafe. The Sea Bob needs no licence, but children under 12 must have a parent with them. Please keep it away from sand and pebbles, as you'd be responsible for any damage.

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