what are bungs on a boat

Bungs are rubber plugs that are used to seal the drain holes in the hull of a boat. They are typically located at the stern of the boat and are used to prevent water from entering the hull. Bungs are essential for preventing boats from sinking and should be checked regularly to ensure they are in good condition and properly secured. When the boat is on its trailer or in storage, the bung should be removed from the bottom of the hull to allow any water that may have accumulated to drain out.
