Triremes had two kinds of sails and two kinds of masts, but before battle the larger sail and the larger mast were always put ashore. Such enormous yards and masts would be very much in the way on boats of this kind. Regarding the arrangement of the oars of the trireme much controversy has been raised. The theories of thirty or more banks of oars have now been pretty well dismissed. The amount of freeboard that this would have given to a ship must necessarily have been colossal, and militated against the very object they had in view, viz., handiness. It is highly probable that the crew consisted of two hundred rowers, sixty-two on the highest tier, fifty-four on the middle and fifty-four on the lowest, in addition to thirty fighting men stationed on the highest deck. The upper oars would thus pass over what we now call the gunwale, the second and third rows being through port holes. Even when very large numbers of oarsmen are mentioned, we must not suppose that there were so many lines of rowers as that; several men were needed to each oar. Considering their weight and the size of later ships, this would seem to be very necessary. Before we pass from the subject of the trireme, it is not without interest to mention that in the year 1861 Napoleon III. had constructed a trireme 39 metres in length and 5½ metres in beam. She carried 130 oarsmen, who were placed two by two. Of these forty-four were on the first row, the same number on the second, and forty-two on the top. Like her ancestors she had a three-fold spur, a rostrum, and two steering oars. But to us a far more important piece of information lies in the fact that she was actually experimented with on the sea at Cherbourg in good weather. It was found that she bore out all that had ever been written by the ancient historians concerning her: for she was both very fast and could be manœuvred with great ease.[14] According to the ancients, a trireme could average as much as seven and a half knots an hour, covering one hundred and ten during a day. The merchant ship was going at a good pace when she reeled off her five knots an hour. Her average was about sixty knots in a day: but during a whole day and night, with a favourable wind, she was capable of doing as much as a hundred and thirty. Comparing this speed with the craft of to-day, it may be worth noting that the average day’s run of a moderate-sized coaster would work out at a hundred or hundred and twenty knots. The speed of the ships of the Mediterranean was not slow, then, though they would appear ridiculous if compared with some of the marvellous passages made by the famous old clippers of the second half of the nineteenth century of our era.
