Final answer:
The term 'boat' typically refers to lifeboats used in evacuation from a ship, while 'rescue ships' like the Carpathia during the Titanic disaster pick up survivors. Without specific details about the maritime event, it's not possible to accurately name the rescue vessel.
Step-by-step explanation:
The question pertains to a historical event in which survivors from a disaster at sea were picked up by a rescue vessel. Based on various historical accounts that describe maritime disasters and survivor rescues, the term "boat" refers to the smaller vessels, like lifeboats, used to evacuate passengers from a sinking ship, while the vessels that come to the aid of these survivors are usually larger ships, referred to as rescue ships or steamers. In instances like the sinking of the RMS Titanic, rescue ships such as the Carpathia played a critical role in the aftermath of the disaster by rescuing survivors who were stranded in lifeboats. It is important to note that various maritime disasters can have different rescue ships, so without specifying a particular event, one cannot precisely name the boat or ship involved in the rescue.
