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.

Excellent Service from Diamond Marine Services!
★★★★★ October 24,2026
I had a great experience with Diamond Marine Services while working toward getting my captain’s license. They were professional, knowledgeable, and extremely helpful throughout the process. They made everything easier to understand and helped guide me through the steps needed to get my license.
I really appreciate their support, expertise, and commitment to helping me achieve my goal. I highly recommend Diamond Marine Services to anyone looking to obtain their captain’s license or advance their maritime career. Great people and great service!
Sam is da man!

Absolute rock solid service from start to finish
★★★★★ October 21,2026
I was hesitant to spend the money at first, but I would never do this again without them! The process is so much more involved than I anticipated, but Diamond Marine took every call, answered every question with patience, and simplified everything tremendously.
I am incredibly grateful for this team. They have an absolute rock-solid procedure and provide an easy-to-follow roadmap. These guys are complete all-stars, and I couldn't thank them enough! I will happily support them and encourage everyone going through this process to use this amazing team help them through!

It gets easier and easier!
★★★★★ October 18,2026
This was my 3rd time using DMS and it is incredible how they go through submitted docs with such detail. I had some scope changes with my MMC and it was done flawlessly. I received the dreaded email from National Maritime Center looking for more docs that didn't make much sense to me, however with 1 email to Sam and company, I was cleared to print that afternoon!

Trouble navigating thru NAFITA
★★★★★ October 10,2026
I was having much difficulty in finishing my 719K application for a medical certificate. The new system that the USCG uses NAVITA can be difficult as it was for me to navigate my application thru it. With the help from Diamond Marine Services and several of the very knowledgeable folks there they made it easy for me to get my application in to be processed. I certainly reccomend this service to anyone needing assistance with there 719K and especially those that are just starting out to get there first marine credential. You can do everything from start to finish to get your credential and medical certificate. Great company....
