hobie mirage broken rudder

[FeelLikeANumber]

Im really clueless as to what parts I need to fix a broken back rudder. I've looked around online as well as tried 5 different stores around town and have been having no luck. One of the pics is here


I hope that went through right ( im clueless on how to upload pics as well). Anyways hopefully someone knows a part or model number that would fit that set up. I've looked through the hobie website and couldnt find anything similar. Its a hobie mirage I bought off a friend and it looks like its got some years on it due to the amount of sunfade on the boat, seat, and plenty of scratches. Ive got a kayaking trip in two weeks so im in desperation mode right now. All help is appreciated.
