A great gift for your son who likes kayaking would be a new kayak paddle. Kayak paddles can make a big difference in the kayaking experience and there are a variety of options depending on his needs and preferences, such as paddle length and material. Another gift option could be a waterproof bag or case for his kayaking gear, so he can easily transport his equipment to and from the water without worrying about it getting wet. Additionally, if he doesn't already have one, you could consider getting him a kayak roof rack for his car to make it easier for him to transport his kayak to different locations for new kayaking adventures!
Or you can get him a star map with the date when he was born.
