It's actually a good idea to try to intentionally beach if holed and you're reasonably sure you will lose positive buoyancy. This allows people to swim to shore and increases the chance of survival on what will otherwise with certainly toss everyone who doesn't get into a lifeboat into the drink.
The problem is that if you're NOT going to lose positive buoyancy then it is nearly ALWAYS better to make sure you're in deep enough water that you DO NOT ground the keel, as you won't tip over this way (partially filling with water from the bilge up lowers your CG, provided you remain afloat!) Lists -- especially severe ones -- are VERY BAD.
So the key question is whether it was ascertained with certainty that the vessel was holed badly enough to lead to a loss of positive buoyancy. We do not know, and the size of the hole itself is not enough information to determine that.
