Guitarist Matthew Followill has been injured while on board the luxury boat as the band relax whilst taking a short break from touring.
He told The Sun how it happened, "I've got a broken toe right now. I ran into a chair. There was a beer falling off a table and I ran to grab it.
"When I ran over two toes went this way and the other ones went (the other way). I painted the toenail green just to be funny, because it was so heinous."
It is also reported that his cousin Nathan hurt his shoulder while jumping overboard.
