Colorado boat registration is handled by Colorado Parks and Wildlife, not your county clerk

Colorado requires registration for any motorized boat or sailboat over 12 feet long used on public waters. You register through Colorado Parks and Wildlife (CPW), which issues a registration certificate and decal. The process is straightforward if you have the right documents, but it differs from car registration — you cannot renew online, and the decal must be displayed on your boat before you launch.

Registration costs depend on boat length and type. A motorized boat under 16 feet costs less than one over 16 feet; sailboats have separate rates. Non-resident registrations cost more than resident registrations. You can register in person at any CPW office, by mail, or through an authorized vendor (usually a marina or boat dealer). The certificate arrives by mail within two to three weeks if you explore in person or by mail.

Key Takeaways

  • Colorado Parks and Wildlife issues boat registrations, not your county — you need a CPW registration certificate and decal before launching on public water.
  • Motorized boats and sailboats over 12 feet must be registered; boats under 12 feet and non-motorized boats do not require registration.
  • You need proof of ownership (bill of sale, title, or previous registration), your Colorado driver's license or ID, and payment at the time of registration.
  • The registration decal must be affixed to your boat before you use it; registrations do not renew automatically and must be renewed each year by the expiration date.

What documents you need to register a boat in Colorado

Bring proof of ownership to any CPW office. If you are registering a new boat, bring the bill of sale or manufacturer's certificate of origin. If you are registering a used boat, bring the previous registration certificate or a bill of sale signed by the seller. If the boat has a title (some states issue titles for boats; Colorado does not, but you may have one from another state), bring that as well.

You also need a valid Colorado driver's license or ID card showing your current address. If your address has changed since your last registration, bring proof of your new address — a utility bill, lease, or mortgage statement dated within the last 60 days works. Non-residents registering a boat must show a valid out-of-state driver's license and proof of residency in that state.

Where to register and how long it takes

You can register at any Colorado Parks and Wildlife office. The main office is in Denver, but CPW has regional offices in Fort Collins, Grand Junction, Montrose, and Pueblo. Walk-in registration takes about 15 minutes. You pay the registration fee on the spot and receive your certificate when ready, but the decal arrives by mail within two to three weeks.

If you cannot visit an office in person, you can mail your process and documents to CPW. Mail-in registration takes four to six weeks total. You can also register through an authorized vendor — many marinas and boat dealers in Colorado can process registrations on site. Vendor registration usually takes one to two weeks for the decal to arrive by mail.

Do not launch your boat until the decal arrives. The decal must be affixed to the boat before you use it on public water. If you register in person and need to use the boat before the decal arrives, ask CPW for a temporary use permit — they issue these in limited cases for boats registered but not yet decaled.

Registration fees and renewal

Colorado boat registration fees vary by boat length and type. A motorized boat under 16 feet costs less than a motorized boat 16 feet or longer. Sailboats have their own fee structure based on length. Non-resident registrations cost significantly more — roughly double the resident rate. CPW updates fees annually, so check the current rates on the Colorado Parks and Wildlife website before you register.

Registrations expire on December 31 each year, regardless of when you register. If you register in November, your certificate expires in just over a month. Renewals must be done in person, by mail, or through an authorized vendor — there is no online renewal option. You can renew starting October 1 of the year before expiration. Renew before December 31 to avoid a late fee.

What happens if your boat is titled in another state

If you bought the boat in another state and it has a title from that state, you still need a Colorado registration to use it on Colorado public waters. Bring the out-of-state title along with your bill of sale or proof of ownership. CPW will issue a Colorado registration certificate; Colorado does not issue titles for boats, so the out-of-state title remains valid but is not required for Colorado use.

If you are moving to Colorado and bringing a boat, register it with CPW before you launch. Some states require you to surrender an out-of-state registration when you register in a new state, but Colorado does not — you straightforward register with CPW and use the Colorado certificate and decal.

Displaying the registration decal and carrying your certificate

The registration decal must be affixed to the boat in a visible location, usually on the hull near the waterline or on the cabin. The exact placement depends on boat type — CPW specifies where the decal should go when you receive it. The decal must be clearly visible and not obscured by water, dirt, or other boats.

Carry your registration certificate with you whenever you operate the boat. Colorado Parks and Wildlife officers and game wardens can stop and inspect your boat to verify registration. If you cannot produce the certificate or the decal is missing or damaged, you may face a fine. If your decal is damaged or lost, contact CPW for a replacement — there is usually a small replacement fee.

Frequently Asked Questions

Do I need to register a kayak or canoe?

No. Colorado requires registration only for motorized boats and sailboats over 12 feet long. Kayaks, canoes, and other non-motorized boats under 12 feet do not need registration. If your sailboat is 12 feet or shorter, it does not require registration either.

Can I register a boat if I do not have a Colorado address?

Yes, non-residents can register boats in Colorado. You need a valid out-of-state driver's license and proof of residency in your home state. Non-resident registration costs more than resident registration. You can register by mail or through an authorized vendor if you cannot visit a CPW office in person.

What if I sell my boat before the registration expires?

The registration stays with the boat, not the owner. The new owner can use the existing registration until it expires on December 31. The new owner should contact CPW to transfer the registration into their name, though some vendors allow the transfer to happen at renewal time. Bring the bill of sale and your ID to complete the transfer.

How much does Colorado boat registration cost?

Fees vary by boat length and type and are updated annually by Colorado Parks and Wildlife. Motorized boats under 16 feet cost less than those over 16 feet; sailboats have separate rates. Non-resident fees are roughly double resident fees. Check the CPW website for current rates before you register.

What if I lose my registration certificate?

Contact Colorado Parks and Wildlife to request a replacement certificate. You will need to provide your boat information and proof of identity. There is usually a small replacement fee. In the meantime, carry any documentation you have showing you own the boat, such as a bill of sale or the original registration.
