Ah, thank you for clarifying that. The concept of the frigate never ceases to baffle me tbh, I was under the impression that a frigate was just a general name for a wide range of warships and could therefore apply to a ship of the line or lighter warships which were fearsome in their own right. I will edit so that ships of the line are excluded though, thanks for that.
If you note any errors with the other ships don't hesitate to tell me.
