Dave, on impact with whatever, the boat was designed to break in half at that cross member and sink under the target. The depth charge was set to go off at a pre- determined depth.
I can only presume the ring John mentioned was part of the breaking process.
Once he had his vessel locked onto the target, the 'driver' abandoned the boat. One brave cookie!
