Front

In maneuvering board problems, how is the ship's speed represented?

Back

The length of the arrow

Front

What is the first step in constructing a maneuvering board plot?

Back

Plot point R.

Front

If you are going to plot a distance of 32,723 yards, what should the scale be?

Back

4:1

Front

A quantity having both magnitude and direction, represented graphically by an arrow

Back

Vector

Front

A graph containing three parallel scales graduated for different variables; when a straight line connects values of any two, the related value may be read directly from the third at the point intersected by the line.

Front

To find the relative track of another ship, how frequently should you plot ranges and bearings?

Back

It makes no difference

Front

What does an anemometer on a ship measure?

Back

Relative wind speed

Front

You plot the position of another vessel over a time span of 6 minutes. Over that time he hasn't changed bearing, but he has moved one mile closer to you. What type of situation does this describe?

Back

He is going to collide with you soon.

Front

Direction the wind is actually coming from

Back

True wind

Front

On a maneuvering board, the head of the relative wind vector is labeled with
