When is a boats position accurately known?
When it is on a line of position
when it is on a dead reckoning plot
when a fix is obtained
when you take a bearing
If you took a true bearing of 037 at 4:52pm how would you plot it on your chart?
0452 above the line and 037 below the line
037 above the line, 0452 below the line
1652 above the line and 037 below the line
1652 below the line and 037 above the line
A boats intended path over the water is it's:
course
line of position
heading
track
The horizontal direction a boat is to be steered is it's:
course
heading
track
dead reckoning
The graphic representation of a boats course on a chart is the:
dead reckoning
bearing line
track
course line
The horizontal direction that a boat points is it's:
track
heading
course
bearing
How do you plot a heading on your chart?
time above the line and heading below the line
heading above the line and time below the line
you don't plot it
the same as a dead reckoning plot
A DR position is based solely on what?
time
direction
true course steered and calculated distance travelled based on time and speed
the speed of the boat and the fix obtained from two bearings
A DR position is indicated on a chart by what symbol?
a circle
a square
a half circle
a triangle
What always accompanies the DR symbol on DR position?
speed
latitude and longitude
distance
time
The direction travelled from one fix to another is what?
distance made good
course made good
speed made good
heading
If you divide the distance you have gone between two fixes by the time it took, you have determined your:
