AbstractClassical merchantmarine navigation practices are being revolutionized by the advent of the ‘new technology’. The increase in the number, size and speed of ships, the consequent growth in traffic density, and the tendency toward automation have introduced new requirements in navigation for merchant ships. At present, shipboard navigation procedures range from the antiquated to the most sophisticated. We are in a transition period and studies of future time frames indicate the strong possibility of eventual traffic control of ships in certain traffic lanes by the use of satellites. A start has been made in this direction by the introduction at present of recommended traffic lanes in certain areas of the Atlantic.The man‐machine relationship becomes increasingly important with more automation and its implied compression of time for decision making on the part of the nagivator. A prime consideration, therefore, is the human engineering aspects of both techniques and technology. The Maritime Administration, in consonance with its mission of fostering a healthy U. S. Merchant Marine, has undertaken research and development work in this direction which has already culminated in projects which offer great promise for the future.This paper will relate the usual practice of navigation on merchant ships stressing the hardships and the needs of the merchant mariner. At the end, a brief look will be taken at the Maritime Administration navigation pro
