A fender is a protective device designed to absorb kinetic energy during collisions, commonly used in boating to shield vessels and docks from harm. Historically, rope fenders were made from discarded lines, while contemporary versions include rubber, foam, or inflatable designs. Authors such as Samuel Murray described steel-strip fenders scraping pedestrians, while Kate V.
Saint Maur repurposed oak rails as protective barriers for infants. Clarence Edgar Johnson highlighted the fragility of early car fenders, emphasizing their role in automotive history. These varied accounts illustrate the fender’s transformation from a maritime safety tool to a multifunctional shield across different contexts, demonstrating its lasting value in preventing damage caused by impacts.
