QUALITY ALUMINUM WELDING HIN FAQ
What does a QUALITY ALUMINUM WELDING HIN look like?

Is QUALITY ALUMINUM WELDING still in business?
USCG records list QUALITY ALUMINUM WELDING as out of business since 2006. That's common for older hulls — the HIN still decodes normally, and the out-of-business date helps date the boat and guides parts-hunting toward salvage and owner groups rather than a dealer network.
How do I decode the year on a QUALITY ALUMINUM WELDING HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year.
