Abstract:	A STEAMSHIP COMPANY or any agency which is operating a goodly number of vessels today, finds that on each ship the charts and their associated bookwork are duplicated. A shoreside correction service would appear to be a logical answer. But, while a portfolio system, or correction service have been found to be practical for certain applications there are drawbacks to such a system. To rotate all ships’ charts ashore for correction each voyage presents an economic and logistic problem, the solution for which is impractical in the United States. To provide only the charts needed for a particular route is operationally unsafe due to possible diversions. -4 modified correction service seems to be the solution. One shoreside office doing all the “bookwork” each week, while each ship holds a full complement of normally needed charts. This paper will describe in brief the design and operation of one such system.
