The Yacht

A timeless traditional wooden vessel where Greek shipbuilding heritage meets contemporary comfort. Cosmos embodies a quiet, understated luxury, offering an intimate and human-scale experience designed for discerning travellers seeking a refined private yacht charter in the Aegean.

Built in 1979 at the Mavrikos shipyards on Syros Island, she was originally commissioned as a private yacht for a shipowner devoted to Greece and the art of living well. Rediscovered in 2019, Cosmos was thoughtfully restored, preserving her soul while elevating her comfort for a new era of sea travel.

Cabin

Cosmos welcomes guests into a timeless experience at sea. With four elegant cabins accommodating up to eight guests, she offers luxurious accommodation in an intimate setting, a private retreat to explore refined interiors and surrender to the endless blue.

The natural surroundings are omnipresent: our Aegean Sea, the most history-filled sea of the world, famous for its natural wonders and man-made splendor. Cosmos offers a refined way to experience nature and heritage in harmony. Thoughtfully curated with elegance, sustainability, and care shaped around comfort, inviting you to slow down and create lasting memories in the privacy of your own yacht.

Main Deck

Expansive outdoor spaces unfold across a Burma teak sundeck and private main deck, where cushioned lounges and sunbeds frame both bow and stern, inviting long, unhurried moments under the Aegean sky. At the very front, the ship’s bell bears the Cosmos emblem and the image of St. Nicholas, guardian of seafarers, a quiet tribute to maritime tradition.

Inside, the upper deck reveals a welcoming dining and lounge area set beside the bar and all-day refreshment station, offering modern comforts and a relaxed setting to gather, unwind, and enjoy life at sea.

Service Onboard

Centered on personalized service, Cosmos curates bespoke itineraries, chef-crafted menus, immersive shore experiences, and thoughtfully prepared beach setups. Onboard comforts include Wi-Fi, entertainment systems, laundry service, and effortless access to fishing and snorkelling adventures.

Sustainable Commitment

Sustainability is at the heart of Cosmos. Her restoration was guided by responsible choices, using local materials, reconditioned wood, timber from controlled forests, and the craftsmanship of local artisans, honouring both heritage and the environment.

At sea, this commitment continues through locally sourced, seasonal cuisine, biodegradable products, renewable energy support, reduced single-use plastics, and careful waste management. We also strive to give back, supporting local communities and contributing to the protection of the marine environment wherever we sail.
