A merchant or navy ship is to cross a wide ocean in minimum time. With the available data regarding input disturbances and system's — i.e. ship's — performance, this paper is mainly dedicated to the practical implementation of the solution of this non-linear problem. An account of the incompleteness of the various data, while the ship's master and his officers are primarily responsible for damage to ship and cargo, the description of the solution method is given in a most plausible form, so that it is well understandable to the praotical navigator.

This was one of the reasons for using the concept of timefronts. The rather frequent occurrence of conjugate points on tracks, that can be constructed on the basis of the usual necessary conditions as well as the fair possibility that such a curve without conjugate points is only time-optimal in a local sense were other arguments to make a search for the global solution of this problem by means of timefronts.
