Historically, the Urca de Lima was shipwrecked on the shores of Florida after a hurricane.
It isn't exactly clear what happens to the women and slaves from Albinus' Island. Vane takes about 40 men with him, and they all appear to be the former pirates from Albinus' old crew. However, none of the slaves or any of the women appear to be among them.
The design for the Spanish Man O' War is based on the Swedish warship the Vasa, which was built and sunk in 1628, thus the design for the ship is slightly anachronistic and more galleon-like in appearance. The Urca de Lima actually has a more traditional 18th century Ship of the Line design.
