How Did The Compass Help Sailors?
The magnetic compass was an important advance in navigation because it allowed mariners to determine their direction even if clouds obscured their usual astronomical cues such as the North Star. It uses a magnetic needle that can turn freely so that it always points to the north pole of the Earth’s magnetic field.
Why do sailors need a compass?
A compass enables the mariner to check the position of their boat or ship to know if the boat is transversing the path of another boat or is on a collision course. … Two bearing taken 45 deg apart can give the mariner a fix position while a third bearing can provide enough information for a smooth sail.
