About One Blue

Originally launched in 2009 and comprehensively refitted in 2026, the 127ft (39m) One Blue by Oceanline combines proven naval architecture with contemporary interiors and updated systems. Her 6 staterooms – 1 King, 1 Queen, 2 Double and 2 Twin – sleep 12 guests in comfort, while day charters accommodate 12. A seasoned crew of 6 ensures smooth operations and attentive service.

 

Refined Comfort

The 2026 refit brought One Blue up to current standards, and it shows in every detail. Stabilizers keep the yacht rock-steady at anchor and underway at 14 knots, making her a particularly good choice for guests who value calm conditions aboard. The Deck Jacuzzi, a deck jacuzzi, a swim platform, and a swimming pool, and thoughtfully designed social spaces give the yacht a resort-quality feel while retaining the intimacy of a private vessel. Updated finishes throughout the interior provide a welcoming retreat after each day’s adventures.

 

Toys & Tenders

With 12 water toys stowed aboard, One Blue turns every anchorage into an activity hub. The lineup includes two wave runners, a Seabob, two SUP boards, water skis, a wakeboard, two kayaks, and towable inflatables, while the 26ft Brig Falcon tender provides quick access to hidden beaches and reef snorkeling spots. All equipment is maintained and set up by the crew – guests simply step in and go.

 

Your Voyage in Mediterranean

One Blue charters throughout Croatia, Montenegro, Italy and Greece in the Mediterranean, repositioning seasonally to offer the best cruising conditions at any time of year. The recommended charter months are Jul, Aug, when sea conditions and destination access are optimal. A refitted yacht like One Blue brings peace of mind alongside luxury – updated safety systems, modern navigation, and a hull proven across thousands of sea miles. Each itinerary is tailored to the group’s interests.
