Why you need a 12' or 13' rod? Also what is your approximate budget for the rod?
If you think, only by casting very far you can catch a fish, you are wrong.
Already you have landed a Barracuda with your 7 feet rod. I would suggest you to watch other anglers to get an idea of strike zone distance.
I would suggest you to get a 10' rod, braid and a good spinning reel designed for braid. Also plugs which are meant for surfcasting.
If distance is a constraint try to get a better rod from manufactures like St Croix, lamiglas, Century etc.
