Structural Support Topside '23 Tsunami

[abl1111]

Heres a picture of my boat with a newly added hardtop:

I'd like to fortify under the gunnel where the hardtop mounts aft. All is mounted securely to the boat ( the aft mounts each have 3/4", 8"x8" plywood backing plates ). I am finding that the hardtop has a little 'shimmy' in it, side to side due to where it mounts aft flexes ever so slightly. This gunnel area is not designed for this extra stress. There are no cracks, but I would like to get some advice on how I can add support to this area. I was thinking mini bulkheads under the gunnel to minimize any flex. But, I want to make sure that this is the correct way to attack the problem - without creating another. And then, how do Iactually do it.

Thanks.
