. "An aviso (formerly also an adviso) was a kind of dispatch boat or \"advice boat\". The term continues to be used in the French and some other navies. It is similar to the modern use of \"sloop\" in other countries.The Dictionnaire de la Marine Fran\u00E7aise 1788 \u2013 1792 (by Nicolas-Charles Romme) describes avisos as \"small boats designed to carry orders or dispatches\"."@en . .
