Hi Stuart
The keel box is a very simple affair and quite shallow so easy to check for cracks.  Best way is first examine the box from inside the boat - any serious cracks should be obvious.  Then add some water to the bilge box so it covers the bolt - if there is a leak it will drip through underneath.  Don't despair if it does leak.  You can usually fix this by cleaning the outside of the box thoroughly with acetone and glassing over the box inside the boat using a West system epoxy kit.  The only parts you can't get to are the rear of the box under the floor, but that's unlikely to have been damaged.
