The trireme derives its name from its three rows of oars, manned with one man per oar. The early trireme was a development of the penteconter, an ancient warship with a single row of 25 oars on each side (i.e., a single-banked boat), and of the bireme (Ancient Greek: διήρης, diērēs), a warship with two banks of oars, of Phoenician ...
The trireme was a fast attack, light displacement vessel. In order to sustain the bending moments of her considerable length, a tightened rope (hypozomata) was mounted beneath the deck spanning from bow to stern. This was an ingenious way to increase rigidity of the hull. Today in modern construction it is called pre-tensioning. After every ...
By the Athenian trireme era (500 BC), [1] the hull was strengthened by enclosing the bow behind the ram, forming a bulkhead compartment. Instead of using bulkheads to protect ships against rams, Greeks preferred to reinforce the hull with extra timber along the waterline, making larger ships almost resistant to ramming by smaller ones. [2]
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.

The fact that the trireme had three levels of oars (trikrotos naus) led medieval historians, long after the specifics of their construction had been lost, to speculate that the design of the "four", the "five" and the other later ships would proceed logically, i.e. that the quadrireme would have four rows of oars, the quinquereme five, etc. [8 ...
Indeed, just because a ship was designated with a larger type number did not mean it necessarily had or operated all three possible ranks: the quadrireme may have been a simple evolution of a standard trireme, but with two rowers on the top oar; [10] it may also have been a bireme with two men on each oar; or it may just have had a single rank ...
It is the lowest deck in a ship. [6] Poop deck: The deck forming the roof of a poop or poop cabin, built on the upper deck and extending from the mizzenmast aft. Promenade deck: A "wrap-around porch" found on passenger ships and riverboats encircling the superstructure. This can have open railings or be enclosed in glass, or a combination.
For the philosophical question of the ship's identity, see Ship of Theseus.) After the reforms of Cleisthenes, a ship was named for each of the ten tribes that political leader had created; these ships may also have been sacred ships. [4] Another known sacred ship was the Theoris (θεωρίς), a trireme kept for sacred embassies. [5]
