I'm thinking of making a 'realistic' (UCS?) version of the Black Seas Barracuda. But what is its real world counter part?
Brig
The two masted sail plan looks VERY brig-y to me. But the stern/cabin are really ornate for a brig.
Polacca
Common in the Mediterranean (which would include the Black Sea) and have a little more ornate stern. It's a little obscure for such a famous ship and the sail plan is a little different.
Armed East Indiaman
Might work, except East Indiaman were not really a type of ship, rather they were trading vessels operating under a charter.
17th Century Frigate
This absolutely nails the stern ornamentation, but the BSB is not a two-decked ship, might be too big for a pirate crew to arm/crew.
What do you think?
