Note 602 — ELIZABETH 1558-1603
Reading edition
Pipe Office Accounts, 2232. The distinction between overlop and deck is not always clear. Sometimes overlop appears to mean a deck running the whole length of the ship, as distinguished from a forecastle or poop deck, and at other times a slight lower deck not intended to carry guns. This last became its ultimate meaning, and it is used in this sense in relation to the Defiance and Warspite.
