The annual registration fees are determined by the length of the boat. Current fees are as follows:
- Less than 20 feet in length - $35.25
- 20 feet to less than 30 feet - $45.25
- 30 feet or greater - $75.25

Purchasing a Boat
When you purchase a boat, you may use your Bill of Sale as a temporary registration for 30 days. If purchasing a boat from a private party, have the seller provide you with a Bill of Sale to serve as your proof of ownership. An acceptable bill of sale includes:
- both the seller and buyer’s printed names and signatures,
- the boat hull identification number (if any),
- the boat make, model and year (if known) and
- the date of the sale.
An acceptable private party to private party Bill of Sale template can be downloaded here for your use. The Bill of Sale must be carried on the boat while operating until the registration decals and card get to you in the mail.
Sorry, at this time, on-line registration for a newly purchased boat is 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 needs to be placed to the left of the Registration number on both sides of the boat.
