Relative vector
Relative vectors on targets that are not
moving over the ground such as land, nav-
igational marks and ships at anchor will
represent the reciprocal of own ship's
ground track. A target whose vector pass-
es through own ship is on a collision
course.
Vector time and vector reference can be
set from the [TT/AIS] page in the [Overlay/
NAV Tools] box. Click the vector length
and vector reference indications to set
them.
