How about a personalized water ski? You can have her/his name or a special message engraved on the ski. Alternatively, you could gift her/him tickets to a water ski event or book a personalized water skiing lesson with a skilled instructor. If your friend prefers relaxation, you could gift a cozy beach towel with a water skiing motif or a water-resistant sunscreen lotion to keep them protected when they are out on the water.
Or you can get her/him a star map with the date when she/he was born.
