Water logged paddle board.

I recently bought a Bote paddle board and it was water logged. I cut the whole bottom half off of the board exposing the foam. I left it outside in the sun for it to dry out the past couple of days. It lost 10 pounds of water. It’s 30 pounds now. When I stand up and hold the board from the center handle the back of the board is way heavier than the front. Is this normal? Is your paddle board balanced?
