05 · About COSMOS
Step aboard Cosmos, a beautifully restored 1979 traditional wooden motor sailer built at the Mavrikos shipyards on Syros. Originally the private yacht of a shipowner devoted to Greece and the sea, she's been through extensive refits (most recently a major 2026 hull restoration) and now welcomes up to 8 guests across 4 elegant cabins.
With Burma teak decks, mahogany and iroko interiors, and a crew of 4 (captain, chef, steward/ess, deckhand), Cosmos sails the Saronic Gulf and Cyclades from her home port at Alimos Marina, Athens — offering an unhurried, authentically Greek experience built around comfort, privacy, and genuine hospitality.
