Hello, We may have these hatch covers yes. Depends on how hold your kayak is. Is it the Cobra Tandem model or Cobra Tandem Long Reach?

Here is the style of hatch we use now on the Cobra Tandem. Two small round screw on type hatch.

The Long Reach Tandem has 1 small round one and 2 large ones.

The small one is https://boutiqueborealdesign.com/products/6-inch-deckplate-seaward (if out of stock we will have more soon).

The large one is https://boutiqueborealdesign.com/collections/hatch-covers/products/10-hatch-kit-includes-deckplate-rim-hardware?variant=

 Hope this helps\
