"Wigham" is a word of Scottish origin that refers to a type of navigational aid commonly found in maritime settings. Specifically, a wigham is a lantern or an illuminated structure placed on top of a post or tower to guide ships and vessels, particularly in areas with treacherous waters or challenging navigation conditions. It serves as a beacon of light, helping sailors and mariners to safely navigate through hazardous areas, shallow waters, or rocky passages.
The wigham typically comprises a cylindrical housing that encloses a light source, such as a kerosene lamp or an electric bulb, which emits a steady or flashing beam. The housing is often made of a durable material, such as metal, to withstand harsh weather conditions and protect the light source from damage.
The term "wigham" may vary in usage depending on the specific region or context. In some cases, it may be used synonymously with other navigational aids like lighthouses or buoys. However, its original Scottish connotation emphasizes a smaller, more localized structure that's functionally similar to a lighthouse, but usually of a smaller scale.
Overall, the primary purpose of a wigham is to ensure the safety of navigation by providing a visible reference point to guide ships, reduce the risk of accidents, and assist in the accurate calculation of a vessel's position at sea or near coastal areas.
