Flush deck

Flush deck is a term in naval architecture. It can refer to any deck of a ship which is continuous from stem to stern.^{[citation needed]}

History

Flush decks have been in use since the times of the ancient Egyptians. Greco-Roman Trireme often had a flush deck but may have also had a fore and aft castle deck. Flush decks were also common on medieval and Renaissance galleys but some also featured fore and aft castle decks. The medieval Brigantine and later  Brig and Snow ships also featured flush decks.

Two different meanings of "flush"

"Flush deck" with "flush" in its generic meaning of "even or level; forming an unbroken plane", is sometimes applied to vessels, as in describing yachts lacking a raised pilothouse for instance. "Flush deck aircraft carrier" uses "flush deck" in this generic sense.

"Flush deck" in its more specific maritime-architecture sense denotes (for instance) the flush deck destroyers described above: the flush decks are broken by masts, guns, funnels, and other structures and impediments, and are far from being unbroken planes. "Flush deck" in this sense only signifies that the main deck runs the length of the ship and does not end before the stem (with a separate raised forecastle deck forward) or before the stern (with a separate raised or, as seen on many modern warships, lowered quarterdeck rearward).

Types

It has two specific common referents:

• Flush deck aircraft carriers are those with no island superstructure, so that the top deck of the vessel consists of only an unbroken flight deck.^[1]
• "Flush deckers" is a common nickname for a series of American destroyers built in large quantities during or shortly after World War I – the Caldwell, Wickes, and Clemson classes – so called because they lacked the raised forecastle of preceding American destroyers, thus the main deck was a flush deck.^[2]
