California Boat Registration Number Decal Display Laws
California boat registration displaying is easy. When you successfully register your vessel, you’ll receive a certificate and a decal.
Your permanent registration number is preceded by the letters CA. This number must be placed on each side of the bow of the registered vessel in a position that is clearly visible at all times.
The vessel must display the boat number and validation decal as stated below.
- The registration number must be placed on each side of the bow.
- The number must be clearly visible at all times.
- Numbers must be in at least three inch high BLOCK characters.
- The color must contrast with the background color of your boat.
- Letters and numbers must be separated by a space or hyphen.
- The number must read from left to right. Example: CA 3214 BA or CA-3214-BA.
- The validation decal must be displayed within 6 inches before or after and in line with the registration numbers on both sides of the boat’s bow.
It’s your responsibility to make sure your boat is properly marked and documented. It’s also a good idea to keep your papers with the boat in a waterproof case for safekeeping.
