KK: /ˈwɜrkˌboʊt/
A type of boat designed for practical tasks, such as fishing or transporting goods, instead of for leisure or military use.
The workboat was used to transport supplies to the remote island.
Workboat → The word is formed from "work" (from Old English *weorc*, meaning labor or effort) and "boat" (from Old English *bāt*, meaning a small vessel). A workboat is a vessel designed for labor or specific tasks on water.
Think of 'labor' ('work') being done on a 'small vessel' ('boat') — that's why a workboat is a boat used for work.
