  • Abstract:
    The primary objective of this project memorandum is to document our hypotheses of how

    mariners use aids to navigation, how use varies among the various categories of waterway

    users and how use varies with meteorological and other conditions. Another objective is to

    identify specific groups as candidates for in-depth study. Thirdly, the memorandum provides

    the instruments to be used for data collection. Whether they are called boaters, masters,

    pilots or captains, these operators of vessels in U.S.-managed waterways are the ultimate

    users of the Coast Guard Aids to Navigation (ATON), and we have relied on their experience

    in making our assessment of user requirements. This characterization focuses on the vessel operators who use the information provided by

    the existing U.S. Coast Guard ATON, in contrast to the Baseline Analysis report on

    Waterway Users, which focuses on the vessels themselves. This characterization is

    undertaken to make better use of the operators' navigational experience to help us assess the

    effectiveness of current ATON and to assist the Coast Guard as it projects future

    requirements for USCG-provided aids and services by providing a means to assess operator

    expectations. We have considered the increased availabUity of low cost electronic navigation

    systems (LORAN-C and GPS) to a broader spectrum of operators to learn whether the Coast

    Guard should reexamine the requirements for some short-range (physical) ATON.
