While well-maintained triremes would last up to 25 years, during the Peloponnesian War, Athens had to build nearly 20 triremes a year to maintain their fleet of 300. [ 17 ] The Athenian trireme had two great cables of about 47 mm in diameter and twice the ship's length called hypozomata (undergirding), and carried two spares.
The "double-banking" theory is supported by the fact that the 4th-century quinqueremes were housed in the same ship sheds as the triremes, and must therefore have had similar width (c. 16 feet (4.9 m)), which fits with the idea of an evolutionary progression from the one type to the other. [13]
Biremes were typically about 80 feet (24 m) long with a maximum beam width of around 10 feet (3 m). [citation needed] These ships were frequently used by the Romans, as during the second of Caesar's invasions of Britain. The bireme eventually evolved into the trireme. A unit commandant (who was given a tent on the open deck) directed a group of ...
Persian triremes differed from those of the Greek, and used Phoenician design. The third level of rowers in Greek vessels was accommodated by adding a outrigger, but the Persians added to the height of the compartment instead. [4] They reportedly were 110 feet (34 m) to 120 feet (37 m) long and had a beam of 15 feet (4.6 m). [4]

Perhaps it would not be a bad idea to add a note on the marine physics that explains the extremely long and narrow design (by modern standards) of the trireme: as the speed of the vessel rises above the square root of the waterline length (speed in knots, length in feet), the power required to move it through the water begins to increase rapidly.
When Melania landed at the Helsinki Airport in Finland, all eyes were feet which bore a pair of flats (yes, flats) from the French brand. The former model wore the brand's 'Solasofia' flat , which ...
