How about a new sail for his sailboard? You could find out the specifications of his current sailboard and then buy a high-quality sail that's compatible with it. Another idea could be a weekend trip to a popular sailboarding spot that he has always wanted to visit. Or you could also get him a book about sailboarding or a lesson from a professional sailboarding coach to help him improve his technique on the water. I hope these ideas help!
Or you can get him a star map with the date when he was born.
