Weight and the fact that they cant really shoot in multiple directions and that can get u in bad situation if wind just happens not to be in your favor. Also if you miss once with this kind of ship it can be the end for u as well since it takes more time to turn for another shot. Also, i never made a shotgun ship my self.. have been on a few tho and got sunk by one too. Also weight balance wont help, you can have all your cannons point in one direction even if they are not all in the front.

No, they shouldn't be nerfed. There are drawbacks on building ships like this.

Nothing changed about the wood walls on ships in the patch.
