What format should the boat registration numbers be?

The correct format for boat registration numbers in Maine is to start with the letters "ME," followed by a space, then three numerical digits, and ending with a space and two letters. This specific format helps to ensure a consistent and clear identification system for boats operating in state waters. The "ME" prefix designates the registration as being from Maine, while the numbers and letters serve as a unique identifier for the individual boat.

In this case, the structure "ME 123 AB" adheres perfectly to the required format, with the necessary spacing included for clarity. It allows enforcement officials and other users of the waterway to easily read and recognize the registration.
