Why You Need to Register Your Boat
Most U.S. states require registration for boats with a motor, including electric outboards on dinghies, tenders, and inflatable catamarans. Even some non-motorized vessels need to be registered depending on the state. Registration ensures your boat is legal, traceable, and recognized by local authorities.
What You’ll Need to Register Your Inflatable Boat or Catamaran
Here are the typical requirements:
- Proof of ownership (bill of sale, manufacturer’s certificate of origin, or title)
- Hull Identification Number (HIN) or serial number
- Valid photo ID
- Application form from your state boating authority
- Payment for registration fees (varies by state)
If your inflatable doesn’t have a factory-issued HIN, your state may assign one after inspection.
Where to Register Your Boat
Registration is handled by each state’s designated agency. You can find your state’s official boat registration website in this directory. These sites will guide you through the online application, documentation upload, and payment process.
Getting Numbers for Your Tender or Dinghy
Once registered, you’ll receive a registration number that must be displayed on both sides of your boat's bow. These numbers must be at least 3 inches tall and contrast with the background color of your hull. Decals may also be issued and need to be placed according to your state’s rules.
Final Tips
- Keep a copy of your registration on board.
- Renew your registration on time to avoid penalties.
- Check if your trailer also needs to be registered in your state.
Whether you're registering your tender, wondering how to get numbers for your dinghy, or making your inflatable catamaran legal for adventure, taking care of registration is easier than ever—and gives you peace of mind on the water.
