How about a water skiing experience at a nearby lake or resort? You could purchase a gift certificate for a lesson or rental equipment. Or if he already has all the gear, consider getting him a personalized ski rope with his name or favorite sports team. Another idea could be a waterproof camera or phone case so he can capture his water skiing moments on film. Additionally, a coffee table book about the history of water skiing or a biography on a famous water skier could be a great gift for the off-season.
Or you can get him a star map with an important date you share.
