Boat Registration Information
Any boat with a motor or sail operated in Colorado on any public waters must be registered with Colorado State Parks.
To register your boat, complete the Boat Registration and return it to:
Colorado State Parks-Registration Unit
13787 S Highway 85
Littleton, CO 80125
You may also register your boat at many State Parks and offices; for a list of the nearest registration location, click here. Always call ahead to ensure services are available.
The annual registration fees are determined by the length of the boat. For the 2010 Registration season the fees are as follows:
Registrations are valid from January 1 to December 31 each year. This is a flat administrative transaction fee - it cannot be prorated for a partial year's registration and will not be subject to refund if the boat is sold or stolen.
Boat Registration Renewals
Registration renewal cards are mailed to currently registered owners each November. You may also renew your registration online by going to the web address on the back of the renewal card. You MUST have your registration number to renew online or please call 303-791-1920 to get your information.
Purchasing a new boat
When you purchase a boat, you may operate the boat up to 30 days from the date of sale. You must carry your dated bill of sale on board with you. Since the registration process may take up to eight weeks, you will want to complete and submit your boat registration application right away.
Sorry, at this time on-line registrations for a new boat are not available.
Vessels from other states may be operated in Colorado for up to 60 days with a current registration from the owner's state.
Canoes and kayaks, and other craft that do not require registration must be legibly marked with the name and address of the owner.
The Colorado Registration Number assigned to your boat must be painted or attached to each side of the bow on the forward half of the vessel. For general decal placement instructions, see the Registration Decal Placement Brochure.
For boat decal placement, see:
These numbers must be a minimum of 3 inches in height and be of contrasting color to the boat. The yearly decals need to be placed to the left of the Registration number on both sides of the boat.
