Colorado Vessel Registration: Your Guide to Legal Boating in the Centennial State

With breathtaking lakes, winding rivers, and endless blue skies, Colorado is a boater’s paradise. But before you hit Horsetooth Reservoir, Cherry Creek Lake, or the Arkansas River, there’s one key step every boat owner must take: registering your vessel with Colorado Parks and Wildlife (CPW). Whether you’ve just bought your first fishing boat or you’re renewing an old favorite, this guide covers everything you need to know about vessel registration in Colorado.

Who Needs to Register a Vessel in Colorado?

Most boats and personal watercraft used on Colorado’s public waters must be registered with CPW. Here’s the quick rundown:

Required: All motorboats (gas, diesel, electric), sailboats, and personal watercraft (like jet skis and Sea-Doos) must be registered if operated on Colorado lakes, reservoirs, or rivers.
Not Required: Canoes, kayaks, rowboats, and paddleboards without motors do not need to be registered. Boats registered in another state can be used in Colorado for up to 60 consecutive days without re-registering.

How to Register Your Vessel in Colorado

Gather Required Documents:
- Proof of ownership (bill of sale, manufacturer’s certificate of origin, or out-of-state title/registration)
- Hull Identification Number (HIN) for boats made after 1972
- Completed vessel registration form (available from CPW or online)
- Payment for registration fee (see below)
Submit Your Application:
- You can register your boat in person at any CPW office, participating agent (like some marinas and sporting goods stores), or by mail. Renewals can also be done online for most vessels.
Receive Your Certificate and Decals:
- Once processed, you’ll receive a Certificate of Number (keep this on board at all times) and two registration decals for the current year. Decals must be displayed correctly on both sides of your boat’s bow.

Colorado Vessel Registration Fees (2024)

Less than 20 feet: $35.25
20 feet to less than 30 feet: $45.25
30 feet or more: $75.25

Fees are valid for one year (January 1 – December 31), regardless of when you register. Be sure to renew annually before the expiration date to avoid late fees and tickets.

Where to Display Registration Numbers and Decals

Your Colorado registration number must be painted or attached to both sides of the forward half of the vessel, in block letters at least three inches high, contrasting with the hull color.
Decals go three inches behind (toward the stern) the registration numbers on both sides of the bow.
Make sure numbers and decals are always visible and in good condition.

Renewals, Transfers, and Special Cases

Renewals: Can be done online, by mail, or in person. CPW sends reminders, but it’s your responsibility to keep your registration up to date.
Transfers: When buying or selling a used boat, transfer the registration within 15 days. Both the buyer and seller should complete the bill of sale, and the new owner applies for registration in their name.
Lost or Damaged Certificates/Decals: Request replacements from CPW for a small fee.
Change of Address: Notify CPW within 15 days of moving.
U.S. Coast Guard Documented Vessels: Must obtain a Colorado Certificate of Decal to operate on state waters.

Boating Safety and Aquatic Nuisance Species (ANS) Requirements

Registration is only one part of legal boating. Colorado requires all boaters to follow safety rules and strongly encourages everyone to take a boating safety course—especially for new boaters or those operating personal watercraft. In addition, all motorized and trailered vessels must be inspected for aquatic nuisance species (like zebra and quagga mussels) before launching at many lakes and reservoirs. This helps protect Colorado’s beautiful waters for everyone.

Penalties for Not Registering Your Vessel

Operating an unregistered or expired boat can lead to fines, tickets, or being denied access to boat ramps and marinas. It’s also illegal to use another vessel’s registration number or decals. Keeping your boat registered is the simplest way to avoid hassle and enjoy a stress-free season on the water.

Selling or Buying a Boat in Colorado

Complete a Bill of Sale: Must include the buyer’s and seller’s names, vessel description (registration number, make, model, year, length, HIN), and sale price.
Transfer Registration: The buyer should apply for registration within 15 days of purchase. The seller should remove their name from the vessel record.
Clear Any Liens: If the boat has a loan or lien, ensure it’s cleared before selling.

Tips for Smooth Registration

Double-check all paperwork before submitting—missing information or an unreadable HIN can delay registration.
Keep your certificate on board whenever you use your vessel.
Renew your registration before boating season starts to avoid any interruptions.
For homemade or rebuilt boats, contact CPW for inspection and special requirements.
If you move or your boat changes ownership, update CPW records right away.
