I hope your son heals quickly!

Seems that whatever happened to your son was independent of you running two frames; it didn't happen because you were on your big frame--you just didn't notice it because it was behind you, correct?
Removing the stern frame would have eliminated this hazard for today, but the hazard still could have existed next summer when you row from it?
Gap between the straight section and the kick?
Please update this thread with pics when you get to the remodel (after life calms down and your son is on the mend, of course!)
Not nit-picking, just looking for insight/lessons learned that we all can take away.
