So if the sun isn’t in multiple places at once said sailors would get weird and unreliable results. WebIn early navigation days, sailors could not determine longitude, but did know how to find latitude. By knowing this, navigators could find the latitude line and sail east or west along it to reach their destination. The mariner’s astrolabe was very useful for this task. Despite being a useful tool, the mariner’s astrolabe had its problems. earbuds with mic meijer
