Hello,

I'm using the Noetic distribution of ROS, in the Gazebo 11 environment, on Ubuntu 22.04. I want to work on a surface vehicle in a gazebo environment. I have done research on this from various sources. I have no problem adding boat and ocean objects in the Gazebo environment. But the boat does not stay on the water, it falls.

My Gazebo environment crashes when I add the plugin included in this resource. Can you help me?
