Boat not rotating on roll axis

Hi, Im stuck on this issue I've been having. I took the DTCHullWave case and want to simulate waves hitting the side of the hull so it can roll. I changed the setup so that the waves flow from inlet to outlet against a rotated version of the hull. I then added a joint in the dynamic mesh dict to allow the hull to roll along its center of mass lengthwise. However, when I run the simulation, the hull is still stationary, and the alpha.water looks super weird. I attached a picture to show. I also pasted my dynamic mesh dict below as well. Would appreciate any help
