One other note, re "Light Seconds": I only know of ONE in the RN before the end of the Napoleonic era and the subsequent realignment of the rating system and upgunning of most surviving 80's - the 1757 razeeing of 1719 HMS Royal William into a flush-decked three-decker, which ultimately evolved into the Barfleur 90/98's. Maybe the French or Spanish or others had some, though...
