It was mentioned to me that there was a construction foam being used
to replace rotted floor stingers. It was easily worked by hand carving
to match the hull floor and could be epoxyed to the fiberglass floor
and the floor boards could be screwed in to it. Unfortunately, my
friend didn't know the name of the foam. If anyone has heard of this
foam ,its properties, and where to get I would appreciate the
information. Or any information on replacing stingers on a 19' Oday
Rhodes.

Thanks,
JB
