A galleass is not something you wear, jOhn, it's an ancient ship. It was a compromise between the galleon and the galley, hence, galleass. It looked like a very large, long galleon, with a midsection mounting a huge bank of oars on each side. Sometimes 2 or 3 tiers of oars on the bigger galleasses. They were very impressive looking, but proved to be vulnerable in battle. The Spanish employed them against the British at the time of the Armada, but without much success. They could not mount as many heavy guns as a galleon, because the oars took up the midsection. They were also less seaworthy on the high seas, but, like galleys, were much more manueverable when there was little or no wind. Thus they were useful in certain situations. The galleass, like the galley, had a ram at the front for ramming other ships. Although they failed as an effective ship in the Atlantic, they remained popular in Mediterranean waters for some time, as did the smaller galleys.

Galleons, however, ruled the seven seas, and proved far more formidable as fighting ships.
