Colorado does not issue a boating license in the traditional sense. What the state requires instead is a Boating Safety Certificate, and only for operators aged 14 through 17. If you are 18 or older, you can legally operate a motorboat or personal watercraft on Colorado’s public waters with no course, test, or state-issued credential. That said, every boat on the water still has to be registered, carry an aquatic nuisance species stamp, and meet equipment rules, so “no license” is not the same as “nothing to do.”
Who Needs a Boating Safety Certificate
A law that took effect June 1, 2024 raised the age threshold for Colorado’s boating education requirement. No one under 18 may operate a motorboat, including a jet ski or other personal watercraft, on any public water in the state unless they hold a valid Boating Safety Certificate.1Justia Law. Colorado Revised Statutes Title 33 Section 33-13-107.1 – Minimum Age of Motorboat Operators – Penalty – Exception The old rule applied only to 14- and 15-year-olds. Now it covers everyone aged 14 through 17.2Colorado Parks and Wildlife. Colorado Parks and Wildlife Shares Boating Safety Tips in Support of National Safe Boating Week
Children under 14 are prohibited from operating any motorboat or personal watercraft on Colorado’s public waters. No certificate or parental supervision changes that. The restriction does not apply to boats operated on bodies of water located entirely on private property.1Justia Law. Colorado Revised Statutes Title 33 Section 33-13-107.1 – Minimum Age of Motorboat Operators – Penalty – Exception
One rule catches parents off guard at the marina: vessel rental businesses cannot lease a motorboat to anyone under 18 unless that person holds a valid certificate. If you plan to let your teenager drive a rental, get the certificate taken care of first.
How to Get the Certificate
Colorado Parks and Wildlife approves several online providers, and the course can also be taken in person or through a virtual classroom. Currently approved online providers include BoatEd, BoaterExam, BoatUS, BoatTests101, Recademics, and AceBoater.3Colorado Parks and Wildlife. Boating Safety In-person classes are offered through the U.S. Coast Guard Auxiliary and U.S. Power Squadrons, among others. All approved courses are recognized by the National Association of State Boating Law Administrators.
You register, work through material on navigation rules, safety equipment, emergency procedures, and environmental regulations, and pass a final exam. Most online providers let you print a temporary certificate immediately, with a permanent card mailed afterward. The certificate does not expire. Once earned, it is good for life.
While operating a motorboat, anyone required to hold the certificate must keep it on their person or in an accessible spot on the vessel. If a wildlife officer asks for it and you cannot produce it, the fine is $100. A court can waive the fine if you later show proof you had completed the course before the stop.1Justia Law. Colorado Revised Statutes Title 33 Section 33-13-107.1 – Minimum Age of Motorboat Operators – Penalty – Exception
Out-of-State Certificates
If a young operator earned a certificate in another state, Colorado will generally accept it, with one important caveat: the course must have been proctored.4United States Coast Guard Boating Safety Division. State Boating Laws – Education Reciprocity An unproctored online-only certificate from another state may not satisfy Colorado’s requirement. When in doubt, confirm with Colorado Parks and Wildlife before your trip rather than at the boat ramp. Visiting adults 18 and older do not need any education certificate at all. The reciprocity question only matters for the 14-to-17 age group.
What You Actually Need Before Launching
The certificate is only one piece. To legally operate a motorboat or sailboat in Colorado, you also need current state registration and an aquatic nuisance species stamp, and your boat has to carry the required equipment.
Vessel Registration
Every motorboat and sailboat on Colorado’s public waters must be registered with Colorado Parks and Wildlife.5Colorado Parks and Wildlife. Register a Boat Registration runs on a calendar year, January 1 through December 31, and must be available to show on demand. Operating an unregistered vessel is a petty offense with a $50 fine.6Justia Law. Colorado Revised Statutes Title 33 Section 33-13-103 – Numbering of Vessels Required – Rules
Annual fees are based on vessel length and include a $1.25 Search and Rescue surcharge:5Colorado Parks and Wildlife. Register a Boat
- Under 20 feet: $36.25
- 20 to under 30 feet: $46.25
- 30 feet or longer: $76.25
Several categories are exempt. Canoes, kayaks, paddleboards, and non-motorized rafts don’t need to be registered, though they must be legibly marked with the owner’s name and address. U.S. Coast Guard documented vessels are exempt from state registration numbers. Boats currently registered in another state can operate in Colorado for up to 60 consecutive days without Colorado registration, and foreign vessels temporarily using Colorado waters are exempt.
Aquatic Nuisance Species Stamp
This is the requirement most new boaters miss. Every motorboat and sailboat registered or launched in Colorado must carry a current Aquatic Nuisance Species stamp on top of the registration fee. The stamp costs $25 for residents and $50 for nonresidents, and it runs on a calendar year.5Colorado Parks and Wildlife. Register a Boat
Colorado also runs mandatory inspection and decontamination stations at many boat ramps. Launching without stopping at a required inspection station is a petty offense carrying a $100 fine. Knowingly transporting aquatic nuisance species is a $500 fine for a first offense and escalates sharply for repeat violations.7Justia Law. Colorado Revised Statutes Title 33 Section 33-10.5-105 – Prohibited Acts – Penalties Clean the hull, trailer, and gear of mud, plants, and debris, and drain every water-holding compartment before leaving an access site.
Required Safety Equipment
Wildlife officers check for this gear, and missing items can shut your day down. The basics:
- One U.S. Coast Guard-approved wearable life jacket per person, properly sized and readily accessible. Children 12 and younger must wear theirs at all times while the vessel is on the water, unless they are in an enclosed cabin or below deck.3Colorado Parks and Wildlife. Boating Safety
- Boats 16 feet or longer must also carry a Type IV throwable device such as a ring buoy or throwable cushion.3Colorado Parks and Wildlife. Boating Safety
- A whistle, horn, or other sound-producing device capable of the signals required by navigation rules.
- A charged, serviceable marine fire extinguisher on most motorboats.
- Navigation lights for any vessel operating between sunset and sunrise.
Personal watercraft follow a stricter rule: everyone aboard a jet ski must wear a life jacket at all times, regardless of age. The same applies to anyone being towed on water skis, a wakeboard, or a tube.
One Thing That Isn’t Like a Driving Ticket
Boating under the influence is not a civil penalty. Operating any motorized, wind-powered, or sail-powered vessel with a blood alcohol concentration of 0.08 or higher is a misdemeanor, and so is operating while impaired by drugs or any combination of alcohol and drugs.8Justia Law. Colorado Revised Statutes Title 33 Section 33-13-108.1 – Operating a Vessel While Under the Influence – Definitions
A first offense carries a mandatory minimum of 5 days up to a maximum of 1 year in county jail, a fine of $600 to $1,000 (which the court may suspend), and 48 to 96 hours of community service. A second offense jumps to a mandatory minimum of 60 days in jail, with the same fine range.8Justia Law. Colorado Revised Statutes Title 33 Section 33-13-108.1 – Operating a Vessel While Under the Influence – Definitions The minimum is not discretionary. Wildlife officers patrol popular reservoirs on summer weekends and do conduct on-water sobriety checks.
