What points did sailors use to navigate
An astrolabe helped sailors because it could determine any direction based on the position of the stars. This is why the astrolabe helped sailors.
Sailors focused on the stars to navigate through unknown territory
The technology in the 1400-1500's made ships better for sailing by the use of rudders, moveable sails, and larger ships. Navigating became better through the use of the astrolabe and better compasses. Mapping also was better.
A compass tells sailors which direction they are going in (North, South, East, or West). This helps the sailors not to get lost and to keep on track to their destination.
They were songs sung by sailors. Back in the day of sailing ships they had no engines to do such heavy work as raising the anchor or trimming the sails. That kind of work had to be done by gangs of men all working together. To help them work together they sang rhythmic songs, which were the origin of shanties.
