The Wrecked Wreck is not really a proper shipwreck at all, it's a partial wreck with only one small room and no meaningful rewards.
The Wrecked Wreck - Map & Route
I'm sure you don't need us to provide a route for you for this one - however it can be easy to miss the locked door on the right hand side when you enter.
Grab your Cutteray, scan the door and then melt the locks. There's a couple of small/medium chests inside but no Reward Chest unfortunately!
