A variety of inventions would fill in the blank. I can think of two ofthand:
1. sextant
which is a navigational instrument containing a graduated 60-degree arc, used for measuring the altitudes of celestial bodies to determine latitude and longitude.
or perhaps
2. compass
which is an instrument for determining directions, as by means of a freely rotating magnetized needle that indicates magnetic north.

Accurate portable ship Clock, Sexton, Compass and Latin style sail triangular design that allowed sailing against the wind. By tacking an angle into the wind then switching and tacking back zig zag.

Sextant - A device used in early navigation that determined, from horizon and azimuth, the latitude that avessel was at.

Magnetic compass. Celestial navigation (using stars to chart your course) doesn't work well, for obvious reasons, in fog.

Compass. Can't make a map without the compass to guide you.

compass most likely, doubt it's a map since it says it IMPROVED navigation

The CHRONOMETER !
without an accurate clock you can not tell where in the world you are in reference to where you started !
That is why Columbus had no idea where he was and guessed WRONG !

sextant, the device ships used to tell what co-ordinates longitude and latitude the were at, so the could plot on paper which way to go.
