# Righting moment for object submerged in water

I am looking to determine the lateral angle at which an underwater camera system will no longer right itself. When on the ocean floor it is $-24.30~\text{kg}$ buoyant with the difference between its center of gravity and buoyancy being $45.14~\text{cm}$. The two centers are almost directly underneath each other with the buoyancy on top.

I am struggling to determine its righting moment because it is fully submerged and most text seems to be aimed at floating vessels.

• Given the camera is meant to be submerged, I think it's pretty likely that the center of buoyancy will be quoted for totally submerged conditions. Work out the angle assuming this, and then test it in a tank. – WetSavannaAnimal Aug 16 '16 at 12:45
