Diamond Marine Services
TOAR, Credential Consulting and More!
Jump start your career!
Our program is reserved for experienced mariners. Mariners holding an OICNW endorsed license (STCW II/1 or II/3) can complete all the assessments in the TOAR with our program. If you do not hold an OICNW endorsement, you may be able to join us but we may not be able to complete the TOAR in its entirety. In addition, the extra sea service needed to upgrade to a mate or master of towing from a lower level license is often a surprise to many. For these reasons, we request to open a line of communication so we can better assess your needs. Mariners holding licenses LESS THAN 500 GRT (master or mate) or those without an OICNW endorsement are accepted on a case by case basis. For more information about this, please feel free to email or call us.

No brainer
★★★★★ November 3,2026
This has been a wonderful experience with Diamond Marine Services. I’ve submitted for upgrades and renewals on my own a bunch of times but I’ll never do it without Diamond Marine’s help again. Their system works great, keeps everything organized, and gives you clear instructions. The part I always hated about doing it alone was not knowing if I’d done things correctly. Having them to consult with along the way removes all the mystery and worry. They happen to be wonderfully nice people too. Everyone I spoke with or had any interaction with was kind and helpful. They’re awesome.

ROADMAP building, submission, and correction
★★★★★ October 31,2026
As always, Sam and the team got it done for me! Sam was able to build me a roadmap so that I was maximizing my time onboard with the correct NVIC’s, classes, tonnage, and ensuring that I was working Tugs with the appropriate routes and tonnage that I needed to accomplish my goals.
We received an email from the NMC that was incorrect, my evaluator misread the OICNW we were asking for. On my own would have required a mind numbingly slow pace email chain, or hours of time on phone calls. Him and his team were able to get it figured out within a day and I actually received my credential in the mail before I would have even been able to get someone on the phone to get it corrected! Hands down the best and most useful service!

Sam helped get us both through Coast Guard limbo!
★★★★★ October 30,2026
My wife and I both ran into hurdles with our Coast Guard captain’s license applications. We were frustrated and felt stuck until we connected with Sam at Diamond Marine Services.
Sam knew how to work through the issues and helped get things moving again. Having someone knowledgeable in our corner took so much stress out of the process.
Huge thanks to Sam and the entire team! Absolutely worth the money, and I’ll recommend them to anyone applying for their captain’s license.
