Registration Requirements – Know the Law
Just like you wouldn’t drive a car without a license plate, sticker, and registration, your boat also needs to be properly registered. Every mechanically powered recreational boat—no matter what state you’re in—must display its registration numbers, have a current state decal, and carry the registration certificate (your “certificate of number”) on board. The only exceptions are law-enforcement, certain government agency boats, and military vessels.
Displaying Your Boat Numbers
To keep things legal and easy to read, your boat numbers must follow these guidelines:
- Placed on the forward section of both the port (left) and starboard (right) sides
- Shown in plain block letters (no script or fancy fonts)
- At least three inches tall
- In a color that contrasts with your hull so they’re easy to see
- Separated by spaces or hyphens, like: ST 1234 AB or ST-1234-AB
Most states also require your registration decal to be placed either immediately before or after the numbers on the port side, usually within six inches.
While many boats need to be registered, some—like canoes, kayaks, and small non-motorized sailboats—may be exempt depending on your state. Always check your state rules so you’re sure.
Using Your Boat in Another State
If your boat is registered where you live but you store or regularly use it in another state, you may be required to register it there too. Many states offer short-term reciprocity, meaning you can visit without paying additional registration fees. However, if your boat “lives” in another state most of the time, expect to register it there as well.
To avoid fines, check the specific rules for both your home state and the state where your boat is kept. State-by-state registration and titling info can be found at the end of this chapter.
