How about a personalized sailboard? You can find companies that offer custom graphics and designs on their sailboards. You could choose a design that fits your grandma's personality or interests and have it printed on the sailboard. Another idea is to book a sailboarding lesson for her or take her on a sailboarding trip to a new location. You could also choose to get her some gear or accessories related to sailboarding, such as a new wetsuit or a waterproof camera to capture all her adventures on the water.
Or you can get her a star map with the date when she was born.
