Sixth edition, enlarged and revised. Quarter bound with blue spine and green boards. The book has been professionally rebound but presumably some time ago as there is wear to the edges of the boards and to the spine; the original gilt spine label has been attached to this newer spine. The lower corner of the title page is a little chipped. Three or four of the illustration pages are detached but the binding is generally tight. The title page proclaims the book to cover many aspects of seamanship including: Names of Principal Parts of a Ship; Masts, Sails, Yards etc.; Knots and Splices; Rigging of Masts; Fitting of Tackles; Rule of the Road and Vessels' Lights; Managing Sails; Mechanical Powers; Trimming Sails; Man Management. Four hundred and twenty illustrations and coloured sheets of national ensigns for Men-of-War and Mercantile Marine, Signal Flags, Compass, Pendants, Flags, International Code, Night Signals, Fog Signals, Semaphore, Sail, Beacon and Squaring Yard Signals. A tremendously interesting book for anyone interested in sailing and seamanship.
