The four galleys were similar to the galeasses in every respect except that of size, in which they were by one-third inferior.
All the ships of the fleet--galeasses, galleys, galleons, and hulks--were so encumbered with top-hamper, so overweighted in proportion to their draught of water, that they could bear but little canvas, even with smooth seas and light and favourable winds.

In violent tempests, therefore, they seemed likely to suffer.

To the eyes of the 16th century these vessels seemed enormous.

A ship of 1300 tons was then a monster rarely seen, and a fleet, numbering from 130 to 150 sail, with an aggregate tonnage of 60,000, seemed sufficient to conquer the world, and to justify the arrogant title, by which it had baptized itself, of the Invincible.
Such was the machinery which Philip had at last set afloat, for the purpose of dethroning Elizabeth and establishing the inquisition in England.

One hundred and forty ships, eleven thousand Spanish veterans, as many more recruits, partly Spanish, partly Portuguese, 2000 grandees, as many galley-slaves, and three hundred barefooted friars and inquisitors.
The plan was simple.
