smoker-craft 1971 canoe

Trying to find out more about a canoe from my dad’s barn. My dad recently passed away so we have no info about this canoe. We did find the original brochure that must have come with it. It’s a Smoker-Craft 16’, called a Royale. Made from Royalex (woodgrain appearance) in 1971. Not sure if this was the only year these were made. Can’t find any info about these anywhere. Any help would be greatly appreciated.
