NAVIGATIONAL PLANNING AND THE USE OF SPECIAL TECHNIQUES

This paper stresses the need for realistic planning prior to a transit of hazardous waters as opposed to the mere study or review of navigational data, no matter how exhaustive. If the planning is realistic, it should be directed toward the most effective use of navigational data, methods, and navigational aids. Therefore, during the planning stage the navigator should determine how he can make most effective use of the information and means available. A study of the navigational situation may reveal the applicability or feasibility of employing certain special techniques as supporting methods, or emergency methods in the event of failure of certain primary navigation sensors. The paper indicates that the planning should include drill in those special techniques infrequently used which may be extremely valuable in an emergency during the transit. Drill, or mental preparation at the very least, should be conducted because the procedures are infrequently used. Some special techniques, which could be extremely valuable during an emergency, may require only a few minutes preparation of commonly available materials. During an emergency, there may not be time, even a few minutes, to prepare the materials,--thus, the need for identifying during the planning those techniques and associated special preparations which can be of considerable help during the transit. In relationship to navigational planning, the paper treats of a variety of special visual and radar techniques. It treats of interim procedures which can be employed during an emergency until more accurate and reliable procedures can be employed.
