The Marlinspike Sailor was written by Hervey Garrett Smith in 1956, and reissued in 1960 and 1971. 1971 is the edition shown here and it is a hardcover, with yellow dust cover. It is a well-known and popular manual on all things about tying rope into various kinds of nautical knots and other useful things. Book is in very nice condition, 1"tear to dust cover on front edge. Otherwise quite nice.
