Blue Sky was founded by visionary Captain Christos Kassandrinós. In the same month, the company reached an agreement to purchase a vessel that was exceptionally large by Thassos standards. The ship had a capacity of 150 passengers, while the largest vessel operating on the island at the time could carry only 49. The ship was purchased from Kalymnos and renamed from Mikros Kosmos 1 to Blue Sky 1.

The company tested the Sunset Cruise route for the first time, operating twice a week from the port of Potos. The route was very well received and showed strong performance.

A full reconstruction of Blue Sky 2 began. The vessel was transformed into the most modern and contemporary daily cruise ship of its kind in Thassos.

The company decided to operate both vessels again, departing from both Potos and Limenaria. Blue Sky 2 returned to service first, followed by Blue Sky 1. During this season, the company introduced the Around the Island route for the first time, which proved to be extremely successful.

The company reached an agreement to charter a brand-new vessel built in 2022, which had not yet completed any commercial voyages. This vessel stands out due to its glass-bottom design, allowing passengers to admire the seabed of Thassos. The ship is 20 meters long and can accommodate up to 129 passengers on deck. The vessel is named E/G–T/R LORETTA and was scheduled to operate cruises from Limenaria, Thassos, for the upcoming tourist season.

The company received an official order from the Port Authority prohibiting routes to the south, southeast, and northeast of Thassos due to multiple complaints filed by an unwanted competing company. This restriction affected all cruise companies on the island, including the complainants themselves. As a result, routes such as the Around Thassos, Salonikiό, Giola, and Alykes could not be operated, and all cruises were limited to western and northwestern areas of the island.

The company made the decision to carry out a complete reconstruction of its entire fleet. Additional and upgraded safety equipment was installed to allow vessels to operate all previously restricted routes as well as open-sea routes. The reconstruction process lasted approximately four months. All vessels received full seaworthiness certification and were declared fully operational.

Blue Sky is currently the only company on the island whose vessels are certified to operate all routes and access every area of Thassos.

The company reached an agreement with another maritime company operating from the Port of Thassos for the chartering of E/G–T/R Blue Sky 2 at a highly favorable rate. For the next two seasons, 2026 and 2027, the vessel will operate routes from the Port of Thassos under a different name and branding.
