If you own a powered boatany boat propelled by the force of an engine., you'll need to register it with your state. All powered boats, as well as some other types of boats, require registration. In some cases with larger recreational boats, you may need to register your boat federally with the U.S. Coast Guard. So check the regulations.
All states will allow boats registered in other states to operate within their waters for a designated period of time. However, if another state eventually becomes your principle location for boating, you will need to transfer your boat’s registration to that state.
