Sky Potato Hail Damage

Its enough to make me fall to my knees and sob like a broken man... well almost. And they'd only just been born! The worst part is that I'd just thinned them back to just the prize specimens as instructed and then they just got belted. If it had happened before thinning I'd have the opportunity to trim out the damaged ones and still have a good crop. What effect having a Mimas sized crater will have on the developing fruit I don't know. Seriously what chance does an apple have against a hail stone that is bigger than it!
