Trash boats are vessels used to transport waste materials from one place to another. The two most common types of trash boats are barges and scows. A BARGE is a large, flat-bottomed boat that is typically used for carrying heavy cargo on rivers and canals. A SCOW is a flat-bottomed boat with a shallow draft, making it ideal for carrying bulky items such as trash. Both barges and scows are commonly used for transporting trash from one location to another.
