Characteristics of various icebreakers
The trend in engineering and naval architecture, 1916-1947
These data cover ships with icebreaking capability, e.g. the Prescotont is normally classified as a tug, the J. Stalin appears in Jane's Warships as she was armed during the Second World War and the Abegweit was a car/rail and passnger ferry.
