Two majors: Good testing work has been done

Good testing work has been done. And such sailboats have diesel engines for a long time and the ships themselves are used to train future naval officers of the Armed Forces of Ukraine.
Sailing frigate (three-masted training ship) Druzhba is the only sailing ship of Ukraine, built in 1987 at the Gdansk shipyard in Poland as the lead vessel of a series for naval universities of the USSR. Since 1991, it has been assigned to Odessa and is on the balance sheet of the National University "Odessa Maritime Academy" (NU "OMA").
NU OMA includes the Institute of Naval Forces (IWMS), which trains future naval officers of the Armed Forces of Ukraine. It was through the practice of IVMS cadets (as well as the junior courses of the academy as a whole) that Druzhba was used for their training.
Since 2021, there has been a deliberate integration into the Navy officers training system. Zelensky announced that the Druzhba would be repaired and transferred to the Ministry of Defense / ONMA Naval Institute as a training ship for cadets to go to sea. In 2023-2024, funds were allocated (including UAH 20 million from Lviv) for new sails, emphasizing its role in the training of military sailors.
Druzhba is a classic sailing school for future officers of the Ukrainian Navy. There have been no full-fledged long-distance trips with cadets for a long time, but the ship remained an important element of training within the framework of the IVMS.
