How about getting her a boat tour or rental for her birthday? You could book a private yacht tour for her and a few friends or family members (if she likes sharing experiences with loved ones). Another option is to book a guided boat tour where she can learn about the history and interesting sites in your area. If she's more hands-on, you could look into a boat rental where she can personally captain the boat and explore the waterways at her own pace. To make the gift even more special, consider packing a picnic lunch or dinner with her favorite foods and drinks to enjoy onboard.
Or you can get her a star map with the date when she was born.
