If I'm not mistake the Galleyas (sp?) was pretty much a galley with raised fighting platforms at the fo'csle & poop decks. Works fine for light guns & marines, but not for heavier guns that were on the horizon. Plus that must have made an oar powered vessel very unmanagable in the wind.
That is why I likened it to the clipper ship as a technological peak. It was the peak in terms of putting firepower on a galley. But of course ocean going vessels got bigger and stronger and there is a fixed maximum in terms of what can be rowed.
Yes, except they had exceptionally long ranged guns, and destroyed the Turkish fleet (20 ships, taken out by 4) before they even got in range.
