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. Weight: 3.4 oz. Dimensions: 7.25", 18.5cm long $19.95 + shipping

LightWedge Night Vision Reading Light The LightWedge night vision reading light is perfect if you need to read your chart or make log entries but also need to preserve your night vision at the helm of your yacht.

The simple push of a button adjusts the light from bright to dim to off. There are no bulbs to burn out. Four AAA batteries (not included) provide 40 hours of light, and they can be easily replaced. The one touch operation on-off switch allows you to conserve battery life when not in use. The LightWedge illuminates your charts, maps and books with ease. It is light and easy to handle and pack. Weight 8.5 oz. (with batteries) Dimensions: 9 1/4" High x 6 3/4" Wide $35.95 + shipping
