Clia is expecting the global cruise industry to grow by 4% this year.
The association believes 23 million passengers will sail this year compared to the 22.1 million who are estimated to have cruised in 2014.
Specialty cruises (including luxury and river) are estimated to have grown 21% annually from 2009 to 2014.
The figures have been published in Clia’s annual State of the Cruise Industry Report.
Adam Goldstein, Clia chairman and president and chief operating officer of Royal Caribbean Cruises, said: “From new ports around the globe to the investment by Clia’s member cruise lines in new, innovative ships, it’s an exciting time for the cruise industry and cruise passengers.
“This year will prove to be another step forward for the entire industry as our members continue to strive to make cruising the best overall vacation experience.”
The report into the industry revealed that 62% of cruises are repeat bookers and 69% rate the cruising experience as a better value than a land based holiday.
The Caribbean remains the main destination with more than a third of global deployment capacity market share in 2015. Asian cruises continue to grow and in 2015, 52 ships will provide 1,065 Asian cruises with a capacity for 2.17 million passengers.
