Navigator's dividers
A triangle
What is the symbol placed on the maneuvering board plot to represent your own vessel?
A capital R
A lower case r
A capital V
A lower case v
The reference vessel is always at the center pole position and so does not need to be marked on the plot.
You own vessel's course and speed are represented by a vector drawn on the diagram. Customarily, the base or tail of the vector at the pole is labeled with a __________ and the head is labeled with a __________.
Lowercase e, lowercase r
Uppercase e, uppercase r
Lowercase r, lowercase e
Uppercase r, uppercase e
Uppercase r, lowercase v
