Does Beyonce OWN a yacht?

I know Beyonce is a mega-rich superstar, but does she really own a yacht? I've been getting emails with pics of her and Jay Z on a yacht. I know celebs commonly RENT yachts and there are some that own one. I also saw on the Travel Channel that one luxury yacht company charges $2 mil a WEEK. If anyone have a link to a website saying that B actually OWNs a yacht, please submit. Thanks!
