I would be surprised if the basalt tanks could get more than 10 tons extra
weight, but I could certainly be wrong.

As I understand it a basketball filled with air weighs more on the scale than a deflated one, but I might be misremembering.
In any case, the
mass will be the weight of the boat
plus the weight of the water on board, so the submerged displacement will indeed be much more than the surfaced displacement.
And if the boat is headed downward at the time of the snagging, you will also have the momentum added into the equation.
All I know for sure is that the Japanese experiment describes a bomb attached to the hook, and that the Allies didn't do it as a matter of course.
