Poros is a compact pine-forested island at the gateway to the Saronic Gulf, separated from the Peloponnese by a channel barely 200 metres wide. At 250,000 euros per week, charter guests board superyachts in the 55 to 65 metre range, carrying multiple guest decks, beach clubs and crews of twelve or more. The Saronic Gulf is well-navigated for vessels of this size, and Poros works well as a starting or finishing base given its connections to Athens and the ferry-served port. Summer conditions are settled with moderate Meltemi winds and calm overnight anchorages throughout the gulf. Yachts at this level offer five or six stateroom-grade cabins, zero-speed stabilisers and full water toy packages covering jet skis, tenders and dive equipment. The advance provisioning allowance typically runs to around 75,000 euros per week, covering fuel, gourmet provisioning, crew gratuity and premium berthing. Charter guests regularly combine Poros with Hydra, the Argolic Gulf and the Cyclades on longer itineraries. Helicopter access is straightforward and the calm Saronic conditions make Poros a reliable base for corporate charters and family groups requiring flexibility. The waterfront handles large tenders without difficulty and the town quay is accessible on foot from the anchorage.
