To elaborate, the overpower on Spanish ships is serious. The numbers on the Nepomucenos assume a 36#/24# or 36#/18# LD/UD load, but most of the time Spanish 74's only packed 24#'s on the LD and 18's or 12's on the UD. They should be no better than a Temeraire, and frankly I would say should most of the time be somewhere between a British 64 and a Bellona, probably closer to the former.
