In addition to dealing with the properties of magnets and the earth's magnetism, three chapters are devoted to the magnetism of the ship, the third explaining in detail the reason for, and composition of, the nine rods. The relation of the components P, Q and R and the rods to the various coefficients are fully explained.

Ship Magnetism and the Magnetic Compass deals with the magnetism of ships and the deviation of the magnetic compass produced by this magnetism. Emphasis is placed on the distinction between the deviation itself and what causes the deviation. Numerous worked examples for exercise are found at the end of each chapter. Comprised of 15 chapters, this volume begins with an introduction to magnetometry, paying particular attention to the magnitude of the forces involved in magnetism and the manner in which these forces act. The strength of a magnetic pole is also considered, along with the angle of deflection of the needle when in two magnetic fields. Subsequent chapters offer a thorough treatment of the strength of the magnetic field and the magnet's moment of inertia and magnetic moment; the earth's magnetic force; and how the different parts of the ship's magnetic force give different types of deviation. The book also explains the heeling error and its causes; the principle underlying successful compass adjustment; the effect of the ship's magnetic forces on the directive force felt by the compass needles; and sub-permanent magnetism. This monograph will be of value to students and practitioners interested in ship magnetism and the magnetic compass.

The Safety of Navigation, implementing SOLAS - Chapter V has been prepared to help ship-owners, masters, crews and industry to understand and comply with the SOLAS Regulations and offers practical guidance on how they should be implemented. It is important that all parties fully understand the requirements of Chapter V and the associated documents and recognise their own specific responsibilities under each Regulation. Of all the international conventions dealing with maritime safety, the most important is the International Convention for the Safety of Life at Sea (SOLAS), which covers a wide range of measures designed to improve the safety of shipping. Substantial revisions to the fifth version of SOLAS came into force on 1 July 2002, with the new Regulations implemented under UK legislation by the Merchant Shipping (Safety of Navigation) Regulations 2002

This book is a pamphlet for the public, intended to introduce them to a new product made by the Sperry Corporation: The gyrocompass. It is a type of non-magnetic compass which is based on a fast-spinning disc and the rotation of the Earth (or another planetary body if used elsewhere in the universe) to find geographical direction automatically. The use of a gyrocompass is one of the seven fundamental ways to determine the heading of a vehicle.
