Custom Boat Names vs. Registration Numbers: What’s Required and What’s Just for Fun?

When it comes to personalizing your boat, adding a name is one of the most enjoyable parts of ownership. But while boat names are a creative expression, registration numbers are a legal requirement—and getting them right matters. In this post, we’ll break down the difference between the two and what’s required by law vs. what’s just for fun.

📝 What Are Boat Registration Numbers?

Boat registration numbers are issued by your state’s boating agency (like the DNR or DMV) when you register your watercraft. These numbers:

• Are usually a combination of letters and numbers (e.g., IN 1234 AB)

• Must be at least 3 inches tall

• Must be displayed on both sides of the bow

• Must contrast with your boat’s color for visibility

• Must be in block letters and read left to right

💡 Tip: Boat registration decals from DOTNumberStore.com are pre-spaced, USCG compliant, and available in a variety of fonts and colors to match your boat’s style.

🚤 Are Boat Names Required?

In most cases, no—boat names are not legally required for recreational boats. Giving your boat a name is purely optional, and it’s a tradition rooted in seafaring culture. Many boaters like to display names on the stern or sides, adding a personal touch (and sometimes humor) to their vessel.

Examples:

• Seas the Day

• Knot on Call

• Reel Therapy

However, for commercial or federally documented vessels, naming is more than just a tradition—it’s a requirement.

🛳️ Federal Boat Name Requirements

If your boat is federally documented with the U.S. Coast Guard, you are required to display:

• The vessel name on both the port and starboard bow

• The vessel name and hailing port on the stern

• All characters must be at least 4 inches tall

• The hailing port must include city and state or U.S. territory

This helps authorities quickly identify commercial and larger vessels, especially in busy ports or during inspections.

🎨 How to Display Both

Want the best of both worlds? Here’s how:

• Place your registration numbers on both sides of the bow (front) per your state’s laws.

• Add your boat name to the stern (rear) or side of your choice in a fun font or color that fits your vibe.

• If you’re federally registered, be sure the lettering for name and hailing port is bold, block-style, and properly sized.

⚓️ Wrap-Up

Your boat’s registration number is a legal requirement that must meet specific guidelines, but your boat’s name is your canvas. Whether you keep it classy or get a little cheeky, make sure both are applied clearly, cleanly, and in compliance with state or federal regulations.
