I am in the process of renewing my 100 ton. Since I’ve first received my license I have gotten a few more certs and licenses. I know my A.B.(w lifeboatsman) needs to be sent in. How about things like Radar, Hazwopper , SafeGulf , CPR/First Aid and things like that? Thank you:cool: ---

AB, Radar, I’ve never had the CG care about the rest. They only seem interested in cpr/first aid for an original. ---

Thank you:cool:[/QUOTE] If you cannot show that you took a radar course in the last five years, you will not get the radar observer endorsement on your MMC. Also, if you have a current MMC with a radar endorsement, but haven’t taken a radar course in the last five years, your endorsement is not valid, even though it is in your MMC. You do not need to renew first aid & cpr if you do not hold STCW endorsements. Hazwoper, safe gulf, etc. are not Coast Guard required. However, your employer may require you to keep them current.
