Thus, the cruising has gradually become a major part of the tourism sector and has become one of the main economic factors for development of shipping industry. Based on analysis of the global demand on cruising this article defines the factors influencing the development of cruise fleet and leading cruise lines and provide a vision for future efforts in field having in mind also the dynamic changes in current situation.","PeriodicalId":286678,"journal":{"name":"Journal of the Union of Scientists - Varna.
