A great gift idea for your girlfriend who loves water skiing would be to take her for a weekend getaway to a lake or beach where she can enjoy her hobby. You can book a rental house or cabin near a water skiing location, and also book a skiing lesson for her with a professional instructor to help her advance her skills.
Another gift option would be to get her a new set of water skiing gear such as skis, gloves, or a lifejacket. You can also consider buying her a gift certificate for a water skiing supply store or for a professional skiing course to help her continue to train and improve her skills. Lastly, you could also create a photo album or video montage of her previous water skiing adventures and your time together on the water as a personal and thoughtful gift.
Or you can get her a star map with the date when she was born.
