Draft is also the depth of water displaced by a boat/ship. Draught (sounds the same as draft) is the wind through a crack or a type of beer. A door or window might be draughty but a beer wont. Drought looks similar but sounds like "drowt" and is what you get when there is a long period of time without rain. Be careful with draft, draught and drought!
