Sausage I'd fix it, if it is less than a couple of years old (ie: was worth something before the incident)
Might not be jumpable but could go another few years.
$100 and a week of evenings is the garage, worth a shot
EDIT: just saw your link - you hit a FISH and snapped the board?

That could remove the fin or crack around finbox, yes. Snap it, no way.
I call manufacturing fault. Is there glass around the snapped area that is obviously not wet out with resin?
If so I say
go warranty - even if it is out of warranty period as it is a defect that would lead to the board not lasting as long as a reasonable person would expect.
