I've launched a website that has tide data and maritime weather for a number of UK seaside locations.

I've added the article structured data to the page, but would adding authorship (my Google+) damage my SEO, as I'm not the writer of the content per se? Obviously if it was a blog post or user generated content, I wouldn't even question adding authorship.
