Captain Mike's OUPV Prep is the most thorough Rules of the Road study app for anyone preparing for the USCG OUPV (six-pack) Captain's License or any USCG deck-license exam. FOCUSED ON RULES OF THE ROAD This app covers the Rules of the Road portion of the USCG exam in depth — Inland and International (COLREGS). It does not cover Deck General, Navigation General, or Chart Plotting. Rules of the Road is the section most candidates fail first, and the only USCG section that requires a 90% score to pass.

However, I have found too many answers that are incorrect. Example: one question said green over white indicates fishing, not trawling… when green over white does in fact mean trawling. **Developer response:** Thanks for the sharp catch, Mark — you're absolutely right: green over white means trawling (Rule 26), and red over white means fishing other than trawling. We've corrected that question and two related ones, and we're auditing the entire 2,282-question bank against the Navigation Rules to catch anything else. The fixes will ship in the next update. Appreciate you taking the time to flag it. ## Frequently asked questions about Captain Mike's OUPV Prep ### What is Captain Mike's OUPV Prep?
