Actually a depth charge going off 8 meters (25 feet) away had a good chance of cracking the hull and sinking her almost immediately. But I don't think that one is really that close. More like twice that, easily. And, it's behind the boat, so the pressure hull is end-on. And, propellors and rudders are not really suceptible to that kind of thing; it would have to be right up next to them to have that kind of effect.
I think you're safe. Shaken, but not stirred.

The British claimed this DC would split a 0.875 inch (22 mm) hull at 20 feet (6.1 m) and force a submarine to surface at about twice that distance. A minol charge introduced in 1942 increased these distances to 26 feet (7.9 m) and 52 feet (15.8 m), respectively.
