A star's 'coordinates' are constant, and refer to its position on the 'celestial
globe' ... a system of coordinates that rotates with the sky and doesn't depend
on where you see it (or even whether you see it).
One possible description of where you see the object in your sky is in terms of
its altitude ... height above the horizon ... and azimuth ... true direction from you.
If the star is due south and on the horizon, then its altitude is zero, and its
azimuth is 180° . Its celestial coordinates could be literally anything, depending
on the date, the time, and where you are located when you see is.
A star with an azimuth of 180 degrees would be due south, and an altitude of 20 degrees would place it 20 degrees above the horizon. So, the star would be in the southern part of the sky, 20 degrees above the horizon.
If the North Star sinks below the horizon, it means you are moving southward. The North Star is located directly above the Earth's North Pole, so as you move away from the North Pole towards the equator in a southerly direction, the angle of the North Star above the horizon will decrease, eventually causing it to disappear below the horizon.
At the equator, the celestial north pole would be north, just at the horizon. In the southern hemisphere, for instance in Australia, the north celestial pole would be north, and as many degrees BELOW the horizon as your latitude. For instance, if you are 10 degrees south of the equator, the celestial north pole would be 10 degrees below the equator.On the other hand, for people in the southern hemisphere, the celestial SOUTH pole would be ABOVE the horizon; this same pole is below the horizon for anybody in the northern hemisphere.
If you are at the equator, the Earth's celestial pole would be at the northern horizon. However, because of atmospheric haze, you would not be able to see Polaris. Below about 5 degrees north, Polaris is not visible.
due south and slightly above the horizon
If Polaris cannot be seen because it is just below the horizon, you must be located at a latitude slightly south of the North Star's position, which is approximately 90 degrees north. Specifically, you would be at a latitude of about 89 degrees south or lower, as Polaris is only visible in the Northern Hemisphere. In this situation, you would be too far south to see Polaris above the horizon.
If Polaris cannot be seen because it is just below the horizon, you would be located at a latitude slightly south of the North Pole, specifically at a latitude near 89 degrees north. At this position, Polaris would be too low on the horizon to be visible. As you move further south, Polaris becomes visible again as you approach the latitude where it appears above the horizon.

The coordinates "2s37e" do not correspond to a city. Instead, they are geographical coordinates that specify a location on the Earth's surface, indicating a point 2 degrees south latitude and 37 degrees east longitude. You would need additional information to determine the city located at those coordinates.
At 45 degrees north latitude, the north celestial pole appears 45 degrees above the northern horizon. At 45 degrees south latitude, the south celestial pole appears 45 degrees above the southern horizon.
A star with an azimuth of 180 degrees would be due south, and an altitude of 20 degrees would place it 20 degrees above the horizon. So, the star would be in the southern part of the sky, 20 degrees above the horizon.
The city closest to this point is Durban, South Africa.
Nairobi is located at 1.3 degrees south, 36.8 degrees east. The nearest city to the coordinates 2 degrees south, 37 degrees east would be Mombasa, a coastal city in Kenya.
The coordinates 52° South and 68° West point to a location in the Southern Ocean, off the coast of South America, near the eastern part of the Falkland Islands. There is no major city at these exact coordinates, as they are situated in a remote area. The nearest significant city would be Stanley, the capital of the Falkland Islands, which is located further north.
If your boat was located at 30 degrees south and 135 degrees west, you would be sailing in the South Pacific Ocean. This area is situated off the coast of South America and is known for its vast expanse of water and relatively remote location. The coordinates place you well away from major landmasses, making it a part of the open ocean.
