Plotting Tool Set

Description

This set comes with the triangle, roll plotter, and dividers.

The Weems & Plath Protractor Triangle is inscribed with contrast enhancing colors making it easier to use. Using two 45° triangles provides an easy method of plotting and performing chart work. With its protractor scales, the triangle is easily aligned in any direction with a chart meridian. Direction is maintained as one triangle is slid along the other to the desired position. Durable, clear vinylite. Short sides 7-1/2″

The Weems & Plath roll plotter consists of a plotter mounted on a roller. The plotter contains distance scales at 1:20,000, 1:40,000, and 1:80,000 to fit the N.O.S. Coast and Harbor Charts, as well as an inch scale. Included are a semi-circular protractor for measuring courses and bearings against a meridian on the chart, and two quarter circle protractors for measuring courses and bearings against a parallel of latitude. Courses and parallel lines are transferred and kept parallel by means of two rollers which are mounted on a slide axis. Used for measuring or laying off courses and distances on a nautical chart. Instructions included. Dims: 3.5″ x 12.5″.

The Weems & Plath dividers weigh only 3 oz. and are heftier than standard size dividers. Made in Germany of a coated marine alloy to resist corrosion. Gear synchronized arms allow one-hand use and provide excellent point alignment, while the center wheel/extension bar construction allows for fast action and precision adjustments. The Weems & Plath Ultralight features hardened stainless steel points and is fully adjustable. Replace a point with lead (supplied), and it becomes a navigator’s compass. Length 7″.
