Colorado Captain's License Requirements

Q: How do I get a captain's license in Colorado?

Getting a captain's license in Colorado means earning a federal USCG credential, not a state-issued one. The path is: document the required sea service (typically 360 days, with at least 3 months — about 90 days — earned within the last 3 years under 46 CFR 11.201(c)); pass a USCG-approved medical exam (CG-719K) and drug test (CG-719P); obtain a TWIC card and current CPR/First Aid; then pass the written exam at REC St. Louis, MO or an approved course provider. Choose OUPV for six-or-fewer-passenger uninspected boats or a Master credential for inspected or larger passenger vessels.

Q: What are the boat captain license requirements in Colorado?

For passenger-for-hire work in Colorado, the credential is federal: OUPV for most six-passenger uninspected charter boats, or Master for inspected passenger vessels and larger passenger counts. Applicants still need sea-service evidence, medical, drug-testing, TWIC, CPR/First Aid, and the required USCG exam or approved course.

Q: Does Colorado issue a separate captain's license?

Colorado may regulate businesses, fishing guides, permits, or local operations, but the captain credential for passenger-for-hire vessel operation is issued by the USCG National Maritime Center.

Q: Should I choose OUPV or Master?

Choose OUPV when the boat is an uninspected passenger vessel carrying six or fewer passengers for hire. Choose a Master credential when the vessel is inspected, carries more than six passengers, or the business plan needs broader authority.

Q: Where do Colorado candidates take the USCG exam?

After the NMC approves the application, candidates can test at REC St. Louis, MO or through an approved course provider that administers the USCG exam.

TL;DR

Colorado does not issue its own captain's license — the credential is the federal USCG OUPV or Master license. Pick OUPV for six-passenger uninspected charter boats and Master for inspected passenger vessels or larger passenger count. The nearest USCG Regional Examination Center is St. Louis, MO. Colorado is landlocked; OUPV Inland is the typical credential for fishing guide services on the larger reservoirs. Few candidates pursue Master tier.

Boat captain license requirements in Colorado

The USCG's charter-boat credential path turns on three practical data points: total days of service, waters served upon, and vessel tonnage. For Coloradooperators, the business question is usually whether the boat carries six or fewer passengers for hire, more than six passengers under inspection, or a mix of inland and near-coastal work around Lake Granby, Blue Mesa Reservoir, Dillon Reservoir.

Six or fewer passengers

Use OUPV when the operation is an uninspected passenger vessel limited to six or fewer passengers for hire.

Check OUPV

More than six passengers

If the vessel carries more than six passengers, compare Master authority before relying on an OUPV route.
