OUR SERVICES

TOAR

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.

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.

Sam and the staff at Diamond Marine Services take all of the stress out of the process of getting renewals, upgrades, etc. They walk ypu through every step and keep you informed during the process. Diamond Marine is highly recommended and I will never use another service.

Stuck in Coast Guard Limbo? Sam is your guy!
★★★★★ October 30,2026
I can’t say enough good things about Sam and the team at Diamond Marine Services! I ran into a few hurdles with my Coast Guard captain’s license application and reached a point where I felt completely stuck. Thankfully, I was introduced to Sam, and he made the process so much easier and far less stressful. Having someone who understood the process and helped get things moving again was a huge relief. If you’re busy, overwhelmed by the paperwork, or feel like your application is stuck in limbo, Sam is your guy. Absolutely worth the money. I’m so grateful for his help and the entire team’s support, they were lifesavers! I’ll be recommending Diamond Marine Services to everyone I know applying for their captain’s license.c

The best way
★★★★★ October 29,2026
I hired Sam to consult on my license and he is and has been professional and available. Took his TOAR assessment today with Captain Simon. Simon is knowledgeable, concise and a pleasure to go thru this assessment with. I recommend highly Sam and Simon as well as this form of assessment to obtain your TOAR.
