Thanks for all the input so far, there doesn't seem to be many old cobia boats out there on google images but I'm going to keep digging till I find some history on these boats.
Here's a few more pictures of the hull as she sits on her trailer. I'll take a top down picture of the bow next time I'm on it. There's evidence that the cap was off the boat once before but I have yet to see any signs of the transom being rebuilt. I'm going to get a surveyor in to look her over and get an insurance appraisal in the next month or so once I take care of some much needed cleaning.

I have her ready for the water as far as the mechanical side of things go and took her for a few trips out the mouth of the harbor. It's given a smooth dry ride so far and it handled the 1' - 2' chop in the basin and through the narrows like it was a flat lake. It rode great through the swells of the open ocean but I took it at low speed and didn't venture very far because I'm still working on building trust in the boat and my skills at the helm.
It's a lot of boat for the 5k I have into it so far with the purchase of the boat, new everything (except coupler and winch) that wasn't aluminum for the trailer and the new exhaust manifolds with a full engine tune up.
