The RADAR Observer Endorsement course is a USCG-approved comprehensive training program covering collision avoidance techniques using RADAR for surface navigation.
It includes instruction on RADAR operation, legal responsibilities, and best practices for safe and efficient vessel operation.
This endorsement is required for many mid and upper-level Coast Guard licenses and can be added to any mariner’s credentials, especially for those operating radar-equipped vessels, even if the equipment is not legally required.
Successful completion results in a Certificate of Competency, which must be submitted to the U.S. Coast Guard to add the RADAR Endorsement to your mariner license.

As of July 22, 2019, mariners are able to renew their RADAR Observer (Unlimited) in three different ways:
- Documenting 360 days of sea service on a RADAR equipped vessel within the last five years.
- Meeting the requirements in 46 CFR 10.227(e)(1)(v) of having instructed a Coast Guard approved or accepted RADAR course at least twice within the past five years.
- Completing an approved or accepted original, refresher, or recertification course (46 CFR 11.480(d)) in the past five years

- RADAR equipment & operation
- RADAR plotting and interpretation

- Navigation
- Rules of the road related to RADAR use
RADAR Observer (Unlimited) qualifies you to operate RADAR systems in ALL waters. An Unlimited Endorsement typically comes with additional days of classroom learning and practical training. A RADAR Observer (Limited) qualifies you to operate on a more limited selection of waters or vessels.
No. Only the USCG can issue official documentation and certifications. To obtain an official certification, mariners must:
- Complete the necessary USCG application form.
- Submit both the Sea School Course Completion Certificate and USCG application form to the USCG.
The USCG then processes the application and issues the official certification.
