Final answer:
Pirates did not have a specific name for ships they successfully sacked. Historical accounts do not indicate a common term for captured ships, and the fate of such vessels varied based on the pirates' intentions.
Step-by-step explanation:
Historically, pirates did not have a specific name for the ships they managed to sack. Instead, they saw these ships as targets for their pillaging activities. Pirate attacks could involve looting cargo, capturing vessels, and demanding ransoms. Historical accounts, such as those during the height of piracy in the Mediterranean and the Caribbean, do not indicate a common term used by pirates to refer to successfully seized ships. Pirates in the ancient and colonial times varied widely in their practices and did not follow a universal code or naming system for their captured prizes.
Pirate history records many instances of maritime piracy where pirates would capture other ships, but these accounts do not specify a particular name given to these vessels post-capture. The captured ships' fate would depend on the pirates' intentions: they could be ransomed, sold, re-purposed for the pirates' use, or even destroyed.
