The Problem of proper Definitions - the "Pinasship" or "Pinnace":
This is an excerpt from the book "The Pirate Ship" -
the discription for that "Pinasship":
"The Dutch 24-gun warship "Postilljon", from an engraving by van de Velde the Younger, c. 1660. Although the Dutch called this type of vessel a "pinasship" (pinnace), it was really a small, three-mast, square-rigged frigate. Her appearance would have been similar to some of the larger buccaneer or pirate vessels of the period, after their conversion to carry additional ordonance. (National Maritime Museum, London)"
