How about these personalized rowing oars? They can be engraved with your boyfriend's name, along with a rowing symbol and the date of your anniversary, making it an extra meaningful and unique gift. Or if you'd rather go for something less expensive, a high-quality rowing-themed t-shirt or hat can also be a great choice. You could also look into getting him a private rowing lesson with a local rowing club.
Or you can get him a star map with the date of your anniversary.
