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.

Do you also need the observation sea service?

We are pleased to be able to offer those who need 30 days of training and observation a platform by which to accumulate the required sea service. This service is available to any mariner that already holds a completed TOAR (does NOT have to be from our program). For more information, please visit out TOAR page or call us at 646-335-6341 to see if this better fits your needs.

Navigating Through Stormy Seas with Diamond Marine Services
January 22,2024
★★★★★ January 22, 2024 Navigating the complex USCG application process can be daunting, but my experience with Diamond Marine Services, led by the incomparable Sam, was nothing short of extraordinary. As someone familiar with the importance of efficient, customer-focused service, I found Sam and his team to exemplify this at every turn. My journey wasn`t without its hurdles. Despite my application being approved for 12 months (to complete my training and submit it), my training completion lagged in the final month (of course December riddled with holidays) . The anxiety was palpable; I was nervous about submitting on time, and to my dismay, my application even timed out with the USCG. However, Sam, with his extraordinary commitment and an impressive escalation contact, turned the tide in my favor. His unbelievable support made the impossible possible, ensuring my application was processed successfully. Sam`s dedication and the team`s expertise in navigating the b
