Where to Find the Hull Number on Your Bayliner Boat

If you’ve ever been asked for your Bayliner’s hull number and had no idea where to look—don’t worry, you’re not alone! Whether you need it for insurance, registration, or servicing, the hull identification number (HIN) is a vital bit of info that’s easy to find once you know where to look.

What Is a Hull Number?

The hull number, officially known as the Hull Identification Number (HIN), is a unique 12-character code assigned to your boat. Think of it as your boat’s fingerprint—it identifies the manufacturer, serial number, and the date of build.

Where to Find It on a Bayliner

On most Bayliner boats, you’ll find the HIN:

  • On the starboard (right-hand) side of the transom – That’s the flat back part of the boat that faces the water when you’re moving forward.
  • Look just below the rub rail (the rubber strip running along the boat’s edge) – it’s usually etched into the fibreglass or displayed on a metal plate.

What It Looks Like

An example Bayliner HIN might look like this: BLBA25CXF405

  • First 3 letters: Manufacturer (BLB = Bayliner)
  • Next 5 characters: Serial number
  • Last 4 characters: Month/year of production

Why It Matters

You’ll need your HIN for:

  • Boat registration
  • Insurance paperwork
  • Selling or transferring ownership
  • Booking services or ordering parts specific to your model

If you’re struggling to find it or it’s been damaged, check your owner’s manual or contact your local Bayliner dealer, or us —to help you locate or verify it.
