Well, the thing is that we had categorization by every other rig (e.g. Category:Barques and Category:Brigantines) except that one. And I can understand some of your reluctance. I deliberately skipped over every warship I came across (not that there are many: for whatever reason most warships are not categorized as being "tall"). But if we are categorizing ships by rig, then I think we need to have a category of full rigged ships.
