> A single huge fore-and-aft sail would be too hard to handle
This isn't quite right, as split fore and aft rigs existed that solved this problem. I suspect it is more that power replaced sail for crossing oceans and square sails make little sense for coastal work so they had already switched to fore and aft rigs (with a few notable exceptions, such as Humberkeels in the north of England).
