A
whaler or
whaling ship is a specialized ship, designed for
whaling, the catching and/or processing of
whales. The former includes the
whale catcher – a steam or diesel-driven vessel with a
harpoon gun mounted at its bow. The latter includes such vessels as the sail or steam-driven
whaleship of the 16th to early 20th century and the floating factory or
factory ship of the modern era. There have also been vessels which combined the two activities, such as the bottlenose whalers of the late 19th and early 20th century, and catcher/factory ships of the modern era.
