Tupper follows on from the previous well-established edition of a text book of naval architecture that many find an invaluable reference in either studying or practising many aspects of marine technology, whether as naval architects, marine engineers, or as sea-going ship engineers and commanders... it builds on the strengths of the previous edition as a very valuable introduction to naval architecture that is clearly written and with well-presented figures...
