The Paralock Plotter
Weems & Plath has developed the Paralock Plotter, a new
parallel rule in a compact size that is particularly suited for use on
modern small chart tables. The primary purpose of the Paralock Plotter is
to enable the transfer of GPS positions rapidly, easily and accurately to
any paper chart. The Paralock Plotter features three unique design
concepts: a locking knob that allows the user to quickly plot a GPS
position on paper charts, two sets of finger holes that enable finger tips
to act as friction pads on the underlying chart, and, although shorter
than standard size rules, the Paralock Plotter opens to the same width as
conventional rules and therefore covers the same chart area.
The most inventive feature of this patented device is the
locking knob located at one of the four pivot points of the rule’s
cross–arms. This knob enables the two rulers to be fixed in any given
separation which allows rapid determination of GPS position. The Paralock
Plotter is only 7.25" long as opposed to the standard rule length of 15",
but its opening width is the same as standard rules. Placing finger tips
in the twin finger holes allows easy operation of the rule and readily
informs the operator if a slip has accidentally occurred while aboard a
rolling or pitching vessel. The Paralock Plotter is made of sturdy, clear
acrylic for maximum chart visibility. It has graduations so it can be used
as a protractor to determine compass bearing. It also has a millimeter
metric scale across the bottom, making it is easy to take distances and
transfer them to a mileage chart.
The Paralock Plotter has all the features of a standard
parallel rule but fits in a pocket and is easier to use. It is perfect for
any boater who keeps track of latitude and longitude coordinates on a
paper chart. Its compact, convenient size makes it the right tool for use
on boats with limited chart space.
