a boat on the water

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Taking to the water in your power boat, sailboat, jet ski​, or canoe is a great way to enjoy Colorado’s many waterways.

Whether you're swimming or boating, it's important to use common sense while you’re out on the water. The Colorado Boating Program helps you get underway safely while enhancing your boating experience.

Registration is required for all power boats and sail boats operating on Colorado waters. Boating accidents that result in injury or death, or damage beyond $500 must be reported using a Boating Accident Report Form. ​

Boating Safely Courses & ANS Inspection Guidance

All Colorado Boating Safely Courses are currently being held in a virtual format to best comply with Colorado's COVID-19 safety precautions. 

After successfully registering for a Boating Safely course, an instructor will contact you 2 days in advance by email to provide you with a virtual meeting link. We are continually monitoring the state's current public health guidance, and will re-assess class safety precautions as guidance changes.

Boaters must comply with CDPHE requirements and CPW's Aquatic Nuisance Species regulations to stop the spread of zebra or quagga mussels and other invasive species.

  • Maintain a social distance of six feet minimum when interacting with CPW staff or other people.
  • Wait for the inspector to wave you forward to the inspection station. 
  • Remain in your vehicle, set the parking brake, and turn the vehicle off.
  • If you have a green seal receipt, please keep your window closed and show it to the inspector through the window glass.
  • Follow the inspector’s instructions if they need you to get out of the vehicle and assist with the inspection. Always maintain six feet minimum between you and staff or any other people.
  • Avoid groups larger than 10 individuals or gathering with anyone that doesn’t reside in your household. Local health board guidance may limit to groups as small as four persons; please know and follow all local health board guidance.

CPW encourages people to take local and state stay-at-home orders seriously, stay home when sick, and limit travel time wherever possible, even for approved recreation. 

Find the most up to date information on how CPW is responding to COVID-19 on the COVID-19 Response page.

Motorboats and sailboats must have an ANS Stamp prior to launching in Colorado.

You do NOT need to manually add another $25 to your payment for the ANS stamp.​
    • Residents with motorboats or sailboats documented by the U.S. Coast Guard or otherwise exempt from in-state registration can purchase the ANS stamp online at​, or at any CPW office or sales location.​
