The term 'Large Barge' can be broken down into two crossword solutions: 'LIGHTER' (7 letters) and 'SCOW' (4 letters). A LIGHTER is a type of barge that is used to transport goods, typically on rivers or canals. It is usually smaller than other barges and is designed to be pushed or towed by a tugboat. A SCOW is a flat-bottomed boat with a shallow draft, making it ideal for use in shallow waters. It is often used for carrying cargo, such as sand, gravel, or other materials. Both lighters and scows are types of large barges, and both are used to transport goods over water.
