Sailing on Friday recounts the growth and decline of what twice became the world's most powerful maritime flect. This is a tale of operatic dimension, peopled with patriots, politicians, industrial geniuses, fearless seamen, and gallant swashbucklers. It includes accounts of little-noted innovations that had long-lasting effects, daring ocean rescues, sea battles, and financial gambles that won or lost millions. Growing stress among diverse forces of mer-chants, shipowners, seafarers, and federal agencies brings this exciting story to an appalling climax.
