� 'Top-sails:' the top-sails are large square sails of the second degree in height and magnitude.
Footnote 5:
� 'Reef:' reefs are certain divisions or spaces by which the principal sails are reduced when the wind increases; and again enlarged proportionally when its force abates.
Footnote 6:
� 'Halyards and top-bow-lines:' halyards are either single ropes or tackles, by which the sails are hoisted up and lowered when the sail is to be extended or reduced. Bow-lines are ropes intended to keep the windward-edge of the sail steady, and prevent it from shaking in an unfavourable wind.
