I am wanting to upgrade my licenses. I hold a 100grt masters with a 500gt. Held since 2009 The USCG says I am eligible for mate 1600. With advance stability, medical care, advance fire and a few others. I’m currently working on ECDIS and ARPA. I just completed Radar unlimited. I have been working on MODUs the past 4 years as a QMED and I occasionally take crew boat gigs. I think I’m ready to step it up to 1600t. I don’t have requirment for Master. 1600 But I do for Mate. Is there any testing from 100t master to 1600t mate? Not the stcw requirments but actual exams. Thank you. ---

Yes. You have to take the exams for Third Mate to get Mate 1600. You might as well ask for Third Mate while you are at it. You’ll probably get a tonnage limit. You may be able to get 25% seatime credit for your QMED time on the unlimited tonnage MODU toward the Third Mate. ---
