The term 'Garbage Tower' refers to a type of vessel known as a SCOW, which is a flat-bottomed BOAT with a blunt bow and stern. It is typically used for carrying bulk cargo such as coal, gravel, or garbage. The term is derived from the Dutch word 'schouwe, ' which means 'BOAT.' Scows are often used in shallow waters, as they require less draft than other vessels. They are also relatively easy to maneuver and can be towed by smaller boats.
