Another option for some boat owners is federal documentation, which means registering your vessel with the U.S. Coast Guard. This offers a few benefits—most importantly, it creates an official paper trail proving ownership, and it’s often required if you plan to take your boat to another country.
Even if your boat is federally documented, you may still need to register it with your state, pay any required taxes, and display the state decal. The safest approach is to place both the state decal and the federal documentation sticker exactly where your paperwork instructs. Keep in mind—it’s illegal to display any other numbers in that same area.
Boats are documented based on how they’re used: commercial, recreational, etc. You can use a commercial vessel for fun, but you cannot use a recreational vessel for commercial work. Doing so can lead to losing your documentation, along with fines or other penalties.
Federal documentation also has some marking requirements:
- Your documentation number must be permanently attached to a structural part of the hull.
- Your boat’s name and home port must be displayed on the hull—usually on the transom.
- Recreational boats need the name and hailing port in 4-inch letters.
- Commercial boats need the same markings on the transom and on both sides of the bow.
Not every boat qualifies for documentation. It’s only available to vessels that measure 5 gross tons or more, which usually means around 30 feet in length. Gross tons refer to volume, not weight—so even a heavy boat might not qualify.
