Two key indicators are used to assess collision risk: <strong>relative bearing<\/strong> and <strong>distance<\/strong>.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Bearing Changes<\/strong>:<br>When one vessel observes another and notes that the bearing (the direction to the other vessel relative to one\u2019s own heading) is <strong>changing<\/strong>, it means the two vessels are not on a straight line of approach. A <strong>constant bearing<\/strong>, on the other hand, with <strong>decreasing distance<\/strong>, is a classical indicator of a potential collision. However, even if the bearing is <strong>not constant<\/strong>, a collision is still possible if both vessels are maneuvering or are on intersecting courses.<\/li>\n\n\n\n<li><strong>Decreasing Distance<\/strong>:<br>A reduction in the range between two vessels suggests that they are closing in on each other. This alone doesn\u2019t necessarily mean a collision will occur, but when combined with a changing bearing, it implies a <strong>crossing or converging situation<\/strong> where one vessel may be moving toward the other\u2019s track. This could lead to a collision if appropriate avoiding action is not taken.<\/li>\n\n\n\n<li><strong>Rule of Good Seamanship and COLREGs<\/strong>:<br>According to the International Regulations for Preventing Collisions at Sea (COLREGs), all navigators must use <strong>all available means<\/strong>, including visual observation, radar, and AIS, to assess risk of collision and act early and decisively. A bearing change with decreasing distance is a clear signal that close monitoring and potential action are needed.<\/li>\n<\/ol>\n\n\n\n<p>In conclusion, even though a constant bearing is a strong indication of a collision course, a <strong>changing bearing with decreasing distance<\/strong> can also be dangerous, particularly in complex or dynamic traffic scenarios. Therefore, the statement is <strong>true<\/strong>: a collision could occur under these circumstances.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner7-172.jpeg\" alt=\"\" class=\"wp-image-225548\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Sb-28 a collision could occur when the distance decreases and the bearing between two vessels changes.
