this ships were from small to medium. They were used from cargo ships, warships, patrol or dispatch boats, and pirate ships. They were mainly used for fishing. The explores can used them to go out to sea.

The difference between magnetic north and true north is the variation or magnetic declination and changes depending on the location. It was very important because it allow navigators to know which way was north, such as helping them finding their way home.

Mercator's projections made using the compass easier and the longitude and latitude helped make maps more accurate and help in marine navigation.

The astrolabe helped navigators sail the seas by helping them find what latitude the ship was sailing on. It was used with the help of an accurate clock and a map. This invention is still used today for when a GPS may fail.

the compass is the most important tool because it help navigate the ocean much faster and they were able to sail whenever and it was easier to find places with this tool.

It helped the navigators use the stars and planets on the horizon to find direction.

It helped the navigators find there way around. Although it wasn't the easiest thing to use, because it had to be completely still. It was hard when they were on a boat with the wind blowing and the waves hitting the boat to keep the astrolabe not moving. Some people can still use it today although it wouldn't be perfect.

the compass was the most important tool because it helps them navigate and know which way they are going.

it was it was faster and you could sail towards the wind

# data[].attributes.body
Because it helped navigators go around the world. The astrolabe wasn't the most accurate, it kept messing up due to weather conditions. Using it at sea would be very difficult due to high winds and the water currents changing. But ashore would certainly be more accurate.

the map was portugal's most prized posseion because other coutries didnt know all around the world. KNOWLEDGE IS POWER

The navigational tools were important because they helped with maps. Helped to travel in water. Helped with direction and stuff like that.

The lateen sails gave it speed and the capacity for sailing windward  it was better then other ships because it wasn't pushed by the winds

The triangular sail gave boats speed and helped navigate the rough and hard journey over oceans.

# data[].attributes.body
The triangular sails gave boats areodynamics and could easily be pushed by the wind. The wind would push the sail foward to push the boat with force.

# data[].attributes.body
The triangular sail made exploring the ocean much easier because the sail worked from different directions to travel unlike the square sails.

# data[].attributes.body
The compass was the most important invention because they helped create maps, people could find things that are based off directions.

# data[].attributes.body
Mos important invention because it allowed them to know what direction they were going without having to use land.

The compass kept sailors on the right track and let them know what direction they were sailing.

The Sextant was a technological advancement that measured the angle between two objects. It included mirors that worked together in order for it t be used. In addition, this invention is quite important because it allowed navigation to improve for the ages.

i think it is the best because it allow you to know where you are going and not get lost
