How about getting him a kite surfing lesson with a professional instructor? Or maybe some new kiteboarding equipment such as a new kite, board or harness? If he already has all the gear he needs, you could also surprise him with a kiteboarding trip to a great location with good wind and waves! Another idea could be a personalized kiteboard bag with his name or initials on it.
Or you can get him a star map with an important date you share.
