Raftsman → It is formed from "raft" (from Old English *ræft*, meaning a flat structure for floating) and "-sman" (meaning a person who). A raftsman is a person who operates or works with a raft.
Think of a 'raft' as a flat structure that floats on water, and the '-sman' indicates a person. So, a raftsman is someone who works with or operates a raft.
