About This Book

The volume traces the evolution of marine propulsion from ancient steam curiosities through experimental paddle and screw systems to the widespread adoption of steam and iron shipbuilding. It surveys early mechanical proposals and nineteenth-century practical developments, examines the technical principles and trials of paddle-wheels and screw propellers, and discusses the transition to iron hulls with detailed case studies of large steam liners including plans, dimensions, engine arrangements, and performance. Accompanying appendices collect measurements, specifications, and contemporary illustrations to document commercial routes, ship types, and engineering advances.

FOOTNOTES:

[469] As will be seen by the above abstract of log, the Adriatic sailing west, made 396 knots, or 455 miles, in (calculating the actual time) 24½ hours, or equal to 18·55 miles per hour; but on her return passage on the same voyage (May 1872), she made (sailing east) 384 knots, or 441½ miles in 23½ hours actual time, which is equal to 18·9 miles per hour.
