large open crack (damaged) hull behind CB well

bought used ds2 with a 3" open crack at bottom of hull several inches behind the CB well
. Appears to be from local damage. No stress cracks around it or connecting to the centerboard well
Is this a stress area or known problem area I should know about before repairing?
How do I repair it assuming full thickness 3" damage
Remainder of the hull looks great without visable repairs
