79 Sceptre cuddy area cracks

[Jeff79Sceptre]

Everyone, I have some major cracking going on in the forward area. Mostly in the floor area where you can step down. I can get this whole area to flex by jumping up and down. I typically carry a 165qt cooler full of ice up there and this is exaggerating the effect. I need to address this so I don't have to do more glasswork. I will be insulating the box to serve as a cooler. That way I don't have to have the cooler and access is easier. I do not believe that there is any support from this forward area to the hull. Would it be ok if I attached to the inside the hull? I will cut out the forward box and epoxy some coosa in there to remedy this.
