What Diamond Marine Services does
Diamond Marine Services, Inc. is a privately held USCG credentialing services company founded in 2009 and headquartered in Red Hook, New York, with a training facility in Fall River, Massachusetts. The company serves professional mariners navigating the U.S. Coast Guard Merchant Mariner Credential (MMC) process, offering three core services: Towing Officer Assessment Record (TOAR) training delivered in-person using a working tug and barge with a USCG-approved designated examiner; credential consulting for original, renewal, and upgrade applications; and partnered online USCG-approved courses (OUPV, Master, AB, Steersman, and various endorsements) delivered through US Captain's Training. Its operational backbone is a proprietary online document portal that allows mariners to upload documents, follow personalized roadmaps, and track application status, supported by a credential consulting team that includes former National Maritime Center evaluators.
The company operates a sales-led go-to-market model, with discovery and engagement driven by phone (646-335-6341), email, and online inquiry forms, plus an email newsletter for TOAR scheduling. Pricing is transparent and tiered: $199 for entry-level MMC applications and small upgrades, $299 for returning mariners, $349 for first-time users, and a flat $2,000 for the one-day TOAR assessment class (with a $300 deposit). Add-on services include Sea Service Evaluation ($150), RUSH 48-hour turnaround ($100), and Records Request ($75), with payments processed through Blue Dog Payments. Customer concentration is entirely individual mariners, with 353 reviews averaging 5.00 stars indicating strong word-of-mouth and high satisfaction.
The business is narrowly scoped to the U.S. maritime credentialing market, with no international footprint, no disclosed outside funding, and no parent company. Strategic moats are built on the team former-NMC expertise, 16 years of operating history, and established USCG/NMC relationships rather than proprietary technology. The company carries no disclosed AI capabilities, patents, awards, or M&A activity, and is led by a small team of approximately 10 employees operating across two physical locations.
