\ \ ``` Hi,<br><br>I was approved to sit for my 500grt in Dec. 2001. I passed first attempt in Oct. 2002. Do I have to test again for a 1600 upgrade now that I have qualifying seatime? Or take all those new classes?<br><br>I've heard something about dates of original seatime, but I also found this USCG checklist link that seems to insinuate that I don't have to test.<br>www.uscg.mil/nmc/checklists/Master%201600%20Gross%20Tons%20Checklist%20MLD-FM-REC-112.pdf<br><br>Does anyone have any info on this situation. I'm also wondering if it goes through, what the crossover requirements are for 3rd Mate unlimited from 1600 oceans?<br><br>Thanks <br> ``` ---

You can crossover from 2nd Mate unlimited to 1600ton master with a 70 question exam, not from 3rd.\\If you took the new (OICNW) exam with the terrestrial module included, you should not have to re-test for 1,600.\\\You can look over the “deck guide” on the [uscg.com/stcw](http://uscg.com/stcw) website. It lists the actual test modules.\ ---

On a similar, but different note, is there any equivalency from 3/M to some tonnage Master? I’ve heard that it’s equivalent to a 100 ton Master, or a “99” ton Master (not sure what the difference there is supposed to be), but I’ve never found a real answer to the question. ---

\New3M,\ The first license that I ever had was a 1600ton Mate and I remember someone telling me something similar to that…like I could run 100ton master with that license. I’m not sure if there was any truth to that, and really didn’t care if there was. ---

Thanks anchorman,\\I really don’t remember if terrestrial was inlcuded or not. I had taken the terrestrial/1600 prep at MPT the month before the exam, and was well prepared so it would be a shame if I wasn’t given the extra few questions when I had the chance. I wasn’t given a choice in Miami. I suppose I will apply and see how it plays out.\ ---

It depends if you got your 500 ton under the old licensing scheme or not:\\NMC Policy letter 01-02 section 11(a) originally read, prior to the correction contained in NMC Policy letter 16-02:\ \ Effective 1 February 2002, an applicant who holds a 500 GRT license and STCW certification that were issued based on the \ and who applies for a 1,600 GRT license and certification must meet the sea service requirements of 46 CFR 10.414 or 10.416.\\No assessments, no exam.\ ---

Wow,\\That is good news. As I said I don’t know if I did the terrestrial module, but I certainly didn’t take all those new classes they added, so I would be classified under old scheme either way. Thanks for the detailed info Doug. ---

I love it when we win every now and then…
