And area's "A" on my boat was filled with puddy, that was old and cracked. Was not doing much except pieces were waiting to dive into the bilge.
I do not recomment the chain saw (i originally thought of pouring that Sea-Cast stuff) so it was unnessary once i decided to cut the inside liner. There was plently of room to remove the core with any primitave instruments of destruction(chisels etc)
Also this approach gives you the ability to bond new stringer knees into the core and glass all in as one.
Now decide on an approach and get to it, spring is on the way .....
