The story
ACI was originally established on 1 July 1983 as a state-owned company with the aim of promoting nautical tourism. It was originally called Adriatic Club Yugoslavia (ACY), which was changed in 1991 to Adriatic Yacht Club (due to the breakup of Yugoslavia and Croatia's independence), although they continued using the ACY surname. In June 1994, after it underwent privatization, the company was re-established as a joint-stock company, adopted its current name and changed their surname to ACI Club accordingly.
ACI is also the biggest single member of the Croatian Association of Marinas (Croatian: Udruženje hrvatskih marina), the national trade association of around 50 individual marinas operating in Croatian waters, meaning that ACI controls nearly half of all marinas in the country. The company's shares are listed on the Zagreb Stock Exchange (ZSE), although a 79% majority stake is held by the Republic of Croatia, more precisely Ministry of Construction, Spatial Planning and State Property as of November 2023.
