Worthing, a seaside resort on the English Channel coast of West Sussex, southeast England, has a long maritime history predating its late 18th-century emergence as a fashionable holiday and residential town. Fishing was a major economic activity for centuries, and still retains a small presence on Worthing's shingle shoreline. Smuggling, usually by sea, also contributed to the growing town's economy. The formerly sandy beach has changed over time, partly because of sea defence work carried out to alleviate concerns over flooding, which has affected the town several times. Large seaweed deposits, driven up from the sea bed, have caused occasional problems, while undersea rock formations off the coast have national importance as a wildlife habitat. There have been many shipwrecks and groundings in the area, and lifeboats were stationed in the town for many years.
