Full and down. A vessel is said to be “full and down” when loaded in such a way that upon sailing she is down to her loadline marks-each winter, summer or tropical loadline whilst the cargo space has been fully utilised. Unless rates of freight for heavy and light cargo vary considerably, best results, from a revenue standpoint, are obtained by loading a ship full and down. To achieve this result, a proper ratio between light and heavy cargo must be determined, which depends on the type and quantity of cargo available.
