Abstract
The subject matter described herein includes a system for improved golf flag stick stability and reduced golf cup and/or flag stick ferrule wear. The system includes a ferrule locatable on an end of a golf flag stick that is inserted in a golf cup. The ferrule has a top portion, a bottom portion, and a sidewall located between the top portion and the bottom portion, where the sidewall tapers inward at an angle selected from the range of 5 degrees to 30 degrees from the top portion to the bottom portion. The system further includes a golf cup having a central aperture for receiving the flag stick. The central aperture is defined by a sidewall that is tapered inward at an angle corresponding to an angle of the ferrule.
