How about a new paddleboard for your grandpa? He would surely love it. You could also consider getting him a nice pair of paddleboarding shoes or a waterproof bag to store his belongings while on the water. Another option is arranging for a guided paddleboarding tour or paddleboarding lesson in a scenic location, which would be a memorable experience for him. Alternatively, you could create a personalized paddleboarding photo album with pictures of him paddleboarding, and include some of your favorite memories with him.
Or you can get him a star map with the date when he was born.
