I would go to CKS and see if they can contact Jackson for you. If they can't, get ahold of jackson yourself. This isn't the kind of failure that normally happens from rocks and things, so it may be be covered as a manufacturer defect.
If not, I would put some epoxy in there to hold it together and keep from spreading and call it good. Also, I'd be gentle particularly getting in the boat and storage/shuttles with the newly fixed area.
