The longship, or galley, being, essentially, an oar vessel, had to fulfil certain simple conditions. She had to be light, or men might not row her. She had to be long, or she might not carry enough oarsmen to propel her with sufficient swiftness. Her lightness, and lack of draught, made it impossible for her to carry much provision; while the number of her oars made it necessary for her to carry a large crew of rowers, in addition to her soldiers and sail trimmers. It was therefore impossible for such a ship to keep the seas for any length of time, even had their build fitted them for the buffetings of the stormy home waters. For short cruises, coast work, rapid forays, and "shock tactics," she was admirable; but she could not stray far from a friendly port, nor put out in foul weather. The roundship, dromond, or cargo boat, was often little more than two beams long, and therefore far too slow to compete with ships of the galley type. She could stand heavy weather better than the galley, and she needed fewer hands, and could carry more provisions, but she was almost useless as a ship of war. In the reign of Henry VIII. the shipwrights of this country began to build ships which combined something of the strength, and capacity of the dromond, with the length and fineness of the galley. The ships they evolved were mainly dependent upon their sails, but they carried a bank of oars on each side, for use in light weather. The galley, or longship, had carried guns on a platform at the bows, pointing forward. But these new vessels carried guns in broadside, in addition to the bow-chasers. These broadside guns were at first mounted _en barbette_, pointing over the bulwarks. Early in the sixteenth century the port-hole, with a hinged lid, was invented, and the guns were then pointed through the ship's sides. As these ships carried more guns than the galleys, they were built more strongly, lest the shock of the explosions should shake them to pieces. They were strong enough to keep the seas in bad weather, yet they had enough of the galley build to enable them to sail fast when the oars were laid inboard. It is thought that they could have made as much as four or five knots an hour. These ships were known as galliasses,[18] and galleons, according to the proportions between their lengths and beams. The galleons were shorter in proportion to their breadth than the galliasses.[19] There was another kind of vessel, the pinnace, which had an even greater proportionate length than the galliasse. Of the three kinds, the galleon, being the shortest in proportion to her breadth, was the least fitted for oar propulsion.
