The word craft since the 17th century has denoted a vehicle or watercraft/vessel that is used for transportation on the sea, in the air or in space. But it can be applied to fictional vessels such as time craft, dimensional craft, and probability craft. It is primarily used as the root word to which prefixes are added, as in aircraft, hovercraft, watercraft, sailcraft and spacecraft. Mutandbarge. jpg A boat is a watercraft 1er vol de l’ A380.
