Discover Astréa 42 – ION, a 6-cabin catamaran that pairs the easy rhythm of a Greek summer cruise with the comfort and stability of a modern multihull. Launched in 2021 and measuring 12.58 metres (41.3 ft) overall, ION is currently based in Porto Cheli — a perfect launchpad for week-long sailing escapes across the Aegean and Ionian, from the Cyclades and Saronic islands down to the Sporades and Dodecanese.
With 10 berths spread across 6 sleeping cabins and 5 bathrooms, ION comfortably accommodates up to guests — well suited to two families travelling together, a circle of friends or a small group exploring secluded coves and turquoise bays at their own pace. Linens, pillows and blankets are included in the charter price, so you can step on board, stow your provisions and head straight for the open water.
Boat equipment features rolling mainsail. It also boasts stand up paddle, tv. Whether you're chasing the meltemi between Mykonos and Paros, anchoring under the volcanic caldera of Santorini, or weaving through the protected channels of the Ionian from Lefkada to Kefalonia and Ithaca, ION gives you the platform to design the trip on your own schedule, with the support of our Greek charter team from check-in to check-out.

The main bases are Athens (Alimos), Lavrion, Mykonos, Paros, Corfu, Lefkada, Preveza, Rhodes, Kos, Skiathos, and Volos. Pick the base that fits your flights and the islands you want to see — Athens for Saronic/Cyclades, Lefkada or Preveza for Ionian, Rhodes/Kos for Dodecanese, Skiathos/Volos for Sporades.
For a 4-cabin Lagoon 42 or Bali 4.2 in shoulder season expect roughly €5,500–€8,500 per week bareboat. Peak season the same boat lands between €9,500 and €13,500. Larger 46–50 ft catamarans run €11,000–€18,000 per week peak. Skipper, hostess, fuel, marina fees, end-cleaning, transit log, and any park fees (Alonissos Marine Park, Lefkas Canal toll) are listed transparently on every quote.
Yes. Greek Port Police require a recognised skipper licence (ICC, RYA Day Skipper or higher, or accepted national equivalent) and a VHF SRC certificate on board. A co-skipper declaration is signed at check-in. If your licence is in doubt, book a skippered charter — the captain handles all licensing and base sign-off.
Around 80% of our Greek charters go bareboat. A skippered charter adds a captain (€180–€220/day plus food) and removes the licensing question. A fully crewed catamaran with captain and hostess (or chef) sits at the luxury end — provisioning, meals and routing handled, you step on board to a stocked galley. Useful when groups are mostly non-sailors or you want full focus on the experience.
Tell us your dates and group — a broker replies with a costed offer, charter agreement and the next available week, usually within the same business day.
Plan 2 to 4 hours under way most days, 12–25 nautical miles between anchorages. Short hops leave plenty of time for swims, lunch ashore at a stone-built taverna, and an early arrival before the afternoon Meltemi peaks (Cyclades, Dodecanese).
Board Saturday late afternoon (typically from 17:00). Return to base Friday by 18:00 for the Friday-evening checks. Sleep on board Friday night. Disembark Saturday by 09:00 in time for the next charter.
Yes — catamarans are the most family-friendly platform we charter. Stable on anchor, wide deck space, easy access to the water from the swim platforms, and separate cabin layouts for parents and children. The protected Saronic Gulf, the calm Ionian (Lefkada–Meganisi–Kefalonia), and the sheltered Sporades Marine Park anchorages are particularly suited to younger crews.
