Which should you choose?

Pick Mariners Learning System if you want to finish entirely online at your own pace. Pick Sea School if you’re in the Southeast and prefer in-person or live-online instruction, or want its broader professional-course catalog. Either way, you still document sea time and obtain a TWIC and a medical exam separately — those steps are the same regardless of school.

Mariners Learning System vs Sea School — FAQ

Is Mariners or Sea School cheaper for an OUPV course?
Sea School’s online OUPV starts around $600 and Mariners’ is around $695, so Sea School’s online option is slightly lower. Final cost depends on format — Sea School’s in-person classes cost more — and neither price includes the separate federal fees (TWIC, USCG application, and a medical exam).
Can I get my captain’s license fully online with either school?
Yes. Mariners is fully online, including an at-home proctored exam. Sea School offers a fully online OUPV as well, plus live-online and in-person formats. Both prepare you for the USCG credential; you complete sea-time documentation, a TWIC, and a physical separately.
Are Mariners and Sea School USCG-approved?
Both market their captain’s-license courses as USCG-approved, but we don’t list an approval as verified unless we’ve independently confirmed it. Confirm a course’s current approval directly with the U.S. Coast Guard’s National Maritime Center before enrolling.
Which is better for a Master license?
Both teach Master-level courses, so it comes down to format and budget — Mariners for fully self-paced online, Sea School for classroom or live sessions. Your tonnage rating is set by the USCG from your documented sea time, not by which school you pick.
