well, lots of practice doesn't equate to sound practice!!!   :^)
this idea would work on the sternward damage, but not at the bow-ward damage
where there is a bulkhead/shoulder.   
I can't effectively reach the inside of the sternward damage from the porthole,
 there's really just enough room for a wrench in there for bolt thru riggers,
I'd do a terrible job sanding the inside surfaces.
What I've done with other boats is to cut another hole for access in a part of
the boat that doesn't need structure.   This would work here, but boat owner
doesn't care about cosmetics.   Thus I'll just build carbon fiber structure on
top of that gunwhale.  The bow-ward damage is still supported by the bulkhead. 
  The stern-ward area design just has heavy duty glass that the rigger bolts
to, I've just copied and increased, and used carbon.
I used two layers of carbon twill, two layers of unidirectional sandwiched
inbetween with regular fiberglass cloth covering top.  
The result will be that the starboard side gunwhale deck will be raised up
above former level with a bit more weight and strength.  Since boat is rigged
left over right, I figured no harm, no foul, and it saved a lot of time in
repair, they will get this boat back right away for their busy learn to row
classes.  
thanks kindly for the suggestion!
