The Captain’s Course Materials Set consists of (5) individual items:

The U.S.C.G. Navigation Rules & Regulations Handbook is a complete copy of the Inland and International Navigation Rules as presented by the United States Coast Guard required for all vessels over 12 meters. This book is required for all our licensing courses.

The Mariner’s Guide to Rules of the Road study aid has been developed by TRLMI to help students and mariners understand and learn The Rules of the Road. The Mariner’s Guide to Rules of the Road is a valuable memory aid. Some individuals learn better by being able to “visualize” the lights and sounds that are a part of the rules. We recommend copying down the Mariner’s Guide to Rules of the Road on paper many times. It is advised to learn the rules instead of memorizing questions and answers. Our students that are able to copy this from memory on test day seem to be more relaxed and do better on the exam. Remember to look on the reverse side as there are many “sayings” that are memory aids also.

The Weems & Plath Protractor Triangle is larger than other navigation triangles on the market, with sides that are 9-1/4 inches (23.50cm) long and a hypotenuse (long side) 13-inches (33.02cm) long. Its clean, uncluttered design is inscribed with contrast enhancing colors (red & black) that display both 320mm & 1-80,000 scales. A hole located at the vertex allows the user to convert the protractor into a quadrant to measure altitude or angle. The triangle is constructed of heavy duty clear 5 mm thick acrylic for durability, with a handle for ease of use. The handle also holds a pencil, and both pencil and pencil sharpener are included.

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/Compass 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″.
