Notes on ship nomenclature

1. Several vessels among the fleet of the Holy League bore the same name. Whilst this is not unheard of among ships belonging to different nationalities, some of the said ships belong to the same nation. These did not seem to be of great importance to Christian commanders at that time. In order to avoid confusion, those vessels bearing the same name were suffixed with ordinal number according to nationality (i.e. Christ of Candia I, Christ of Candia II; Christ of Venice I, Christ of Venice II, etc.).
2. In contrast to their Western contemporaries, Turkish records only show the names of commanders of the ships instead of the names of the ship themselves.
3. In Italian use, various flagships were called by the rank of their commander. A reale ("royal") was personally commanded by a king or his agent; a capitana ("captainess") by a captain general; a padrona ("master") by a padrone.
