CPA graphics
CPA graphics show vectors for your vessel and a selected target. A vector is a line on-
screen showing the predicted courses of your vessel and the selected target if you both
remain on your present course. These vectors vary in length due to boat speed and
vector length set in the MARPA Setup menu.
