The Department for Enterprise says passengers on cruise ships each spend an average of just over £44 on the Isle of Man.
It had refused to release the amount following a freedom of information request last year - but has changed its mind after a review.

Last year, 28 cruise ships were scheduled to visit the Island, bringing 9,756 passengers.
