Name two tools that improved siling and expllain why they were important?

Two tools that significantly improved sailing are the astrolabe and the magnetic compass. The astrolabe allowed sailors to determine their latitude by measuring the angle of celestial bodies, enhancing navigation accuracy during long voyages. The magnetic compass provided a reliable means to ascertain direction, even in overcast conditions or at night, transforming navigation by enabling sailors to maintain their course across vast and featureless oceans. Together, these tools revolutionized maritime exploration and trade.
