For a charter built around comfort, consider Lagoon 400 S2 - 4 + 2 cab. "Emerald Seas" in Lavrion, main port, afloat since 2015. The Saronic Gulf offers short, sheltered passages between Aegina, Poros, Hydra and Spetses — classic Greek harbours within easy reach of Athens.
Up to 12 guests settle in across 4 cabins and 4 bathroom(s). Ideal for slow mornings, long swims, and unhurried passages.
