The term 'BODY BOAT' is a combination of two words, 'BODY' and 'BOAT'. The first word, 'KERN', is a four-letter word meaning 'to form or shape into a ridge or furrow'. This term is often used in the context of metalworking, where it refers to the process of forming a groove or channel in a metal surface. It can also be used to describe the process of creating a pattern or texture in wood or other materials. The second word, 'BOAT', refers to a vessel used for transportation on water. Together, the two words form the term 'BODY BOAT', which is used to refer to a type of BOAT that is designed to fit the contours of a person's BODY, allowing them to move through the water with greater ease and efficiency.
