This course is principally intended for candidates who hold USCG Merchant Mariner’s Licenses and are operating vessels that require a license endorsement as Radar Observer (Unlimited). Students are expected to be able to read and speak English, and have a working knowledge of basic chart interpretation and ability to plot positions using latitude and longitude.

Course Details:

This course provides training to mariners who wish to obtain an endorsement to their US Coast Guard Merchant Mariners License as Radar Observer (Unlimited).

There are three Radar Observer endorsement levels: Rivers, Inland and Unlimited. A Radar Observer endorsement is required on all Master’s licenses over 200 GRT and on all towing vessel licenses.

It is highly recommended that everyone complete the Unlimited course and receive the endorsement for Radar Observer – Unlimited, even if they have an Inland license.

Satisfactory completion of any of these courses satisfies the U.S. Coast Guard requirement for issuance of the endorsement with no further testing at the Coast Guard. Your Radar endorsement must be added to your license by the Coast Guard and must be renewed every five years. Renewal is accomplished by attendance at a U.S. Coast Guard approved Radar Observer Recertification course. Our Unlimited course satisfies the STCW – 2010 requirements for Officer in Charge of a Navigational Watch.

The course provides students with classroom instruction covering the examination topics identified in 46 CFR, Part 11, Sec. 11.305 and Table A-II/1 and Section A-II/1 of the International Convention on Standards of Training, Certification and Watch keeping for Seafarers, 1978, as amended in 2010.

The following assessments fromTable A-II/1 of the STCW Code for Officer in Charge of a Navigational Watch are completed during this course:




Four examinations using a combination of multiple choice questions and the RADAR simulator are designed to evaluate the student’s knowledge and comprehension of RADAR fundamentals, operation and the interpretation and analysis of radar information. Each requires a minimum passing score of 70%.
