The largest class of vessel that floats upon the sea is the _full-rigged
ship_, the distinctive peculiarity of which is, that its three masts are
_all_ square-rigged together, with the addition of one or two
fore-and-aft sails.
As the fore and main masts of a "ship" are exactly similar to those of a
barque, which have been already described, we shall content ourself with
remarking that the _mizzen-mast_ is similar in nearly all respects to
the other two, except that it is smaller. The sails upon it are--the
_spanker_ (a fore-and-aft sail projecting over the quarter-deck), the
_mizzen-top-sail_ and _mizzen-top-gallant-sail_, both of which are
square sails. Above all these a "ship" sometimes puts up small
square-sails called the _royals_; and, above these, _sky-sails_.
