What CaptainsGround is
CaptainsGround is an independent prep tool for USCG captain exams. It builds a question bank from public federal resources such as 33/46 CFR, COLREGs, Inland Rules, NGA Bowditch, and USCG manuals. It is in early access and completely free for now, with a paid tier planned later and discounts for early users. The tool offers courses for OUPV and Master 100 GT, mock exams in the NMC format with 70 questions and a 90-minute limit, an adaptive learning plan, and the FSRS 4 spaced repetition system. Every answer links to a citation source so you can check the rule yourself. It supports OUPV inland and near-coastal paths and Master 25/50/100 GT certificates. The goal is to help mariners understand the rules, not just memorize answers, and to raise exam prep efficiency.

What to watch out for
The tool is free during early access, but a paid tier is planned, so free access rules may change. Early access products can still have gaps, so some questions or features may be incomplete. It is a study aid, not a promise that you will pass; real exam results depend on your own effort. The question bank is built from public sources, so check the official Coast Guard rules for the current version before your test.
