What a wonderful ship! With this triangular sail and stern rudder we are going faster AND safer than ever! Isnt that amazing Diego?
Of course dad! Were very lucky to be traveling in a caravel, instead of a regular ship.
Now nothing will stop us from exploring America!

I think I know what we can do!
There must be a way to make these voyages safer, maybe by improving our maps, but how?
We can show the ocean currents and longitude/latitude lines so people know what currents they'll be phasing and how close they are to the equator and Prime meridian!
The compass says were going Northwest dad.
Diego, to which direction are we headed to?
Make sure you're correct Diego, we don't want to keep going in the wrong direction!
Does anyone know what this is?
Its a compass Mr. Henry!
Both of you are correct!
