Some sort of fragata latina is certainly included in Beta 3.3 just before it became Beta 3.4 because when I was playing "Brave Black Flag", I met one. It's a nice ship, alright. The shortage of cargo space isn't a problem because it has the firepower and crew to take the merchant ship of your choice. Since the merchants are at the front of the convoy, and anyway if you enter battle from the worldmap then you start half way up the enemy line, I can grab a merchant or three and then run away before the escorts can do anything about it. I had a lot of fun with that ship.
