I am confused by your terminology. But rephrasing what the photo shows -
Your boat does not have a hatch, at all. Let alone a hatch cover.
The fact that it does not have that makes sense of it not having a forward bulkhead. That is only needed if you have a dry area up front.
This is an era of boat where the mold was set up to reflect different setups, in your case this was a boat that left the factory not enabled for a front hatched area.
It is more complicated than getting a hatch cover. You would also need a rim, sealent and possibly an inner neoprene cover. Before you even get to affixing a hatch cover.
I suggest you get a float bag, for sure, to fill up the forward area. But you may be able to find bags that operate both as float bags and have dry storage, WRX used to make them, to maximize your use of the forward portion.
