CHAPTER 1
Introduction to Navigation
Introduction
In this chapter, you will be introduced to the world of navigation. As a
Quartermaster, you will be engaged in many aspects of navigation. As
you will learn, navigation is known as both an art and a science.
Don’t
be put off by the science end though, a basic knowledge of mathematics
will suffice your needs. There is no feeling that compares to knowing
that you are part of a team that safely navigates a ship and her crew
across vast expanses of ocean.
You will be a highly visible member of the ship’s crew, after all, your
work station is on the bridge. The bridge is where the captain spends
most of his or her time under way. The bridge is where the orders are
given for the ship to carry out her mission. QMs traditionally maintain
the highest standards of grooming, pride, and professionalism. You
will become the trusted assistant of the navigator, bridge watch officers,
and the captain.
