Coolship

A coolship, or in Dutch/Flemish koelschip, is a type of fermentation vessel used in the production of beer. Traditional coolships are broad, open-top, flat vessels in which the wort cools. The high surface to mass ratio allows for more efficient cooling. Contemporary usage includes any open fermentor used in the production of beer, even when using modern mechanical cooling techniques. Traditional coolships were constructed of wood, but later were lined with iron or copper for better thermal conductivity.
