Weems & Plath Parallel Rulers 12" 305mm For Navigation & Chartwork
With the Weems & Plath Lifetime Warranty
Used to plot a course from a convenient meridian or compass rose on a chart
Using the protractor scale:
This uses any meridian of longitude on a chart to give direction in degrees true. Line up the ruler in the direction required and then walk the rule until the mark at the rear centre is exactly on any meridian of longitude line with rules closed.
Read the direction using the scale of degrees from where the same meridian crosses the ruling edge. Note that the scale is calibrated in both directions, 180 degrees apart, the smaller number giving the easterly direction.
In this way the parallel ruler can be used as a plotter on charts which are badly creased when it is not possible to walk the ruler.
