Note the dried mud areas where nothing was stuck down. You can also see the feather crack of the tabbing at lower right of photo. I just pulled that off by hand.

Near v-berth support on starboard side. Where dark lines are may (probably?) needs more cleaning out?

This is in the bow.  You cansee the balsa looks good, but it is not adhered to the bottom and moisture trickled out.

Front view after removing the wet areas and cutting out the un-adhered area. Note the wide kerfs.  These are what the water followed up. One on the right is filled with nearly 1/2 inch fiberglass.

View of rear.  The dark area onright is wet so I still need to clear a bit more in that direction.

The whole shot so far. It is huge, and tbh, my cheap pin meter shows high moisture all around. There is no dry!

The dotted line is where I left off. I had one little black line to follow back and thought the rest looked pretty good.  Once I cut in it was full of water back there.  The smooth areas are where the balsa was not adhered to the floor at all.

This shows the various ways the floor looks: nice pink smooth fiberglass, icky black fiberglass, areas of fuzzy mat and a lot of unevenness.  How much sanding do I need to do to get it ready for new mat?

Along the sidewall I ran into filler where the balsa core met the wall. You can see a lot of air pockets and thick epoxy.  How smooth does this need to get?

This is the limit of my forward cut and I\'m having the same problem/question.  You can see from the shadows that it is very uneven

This is where I removed the v-berth bunk and will have to replace it someday.  Do I grind everything back at a 12:1 ratio to prepare for that?

V-berth side. The bunk does not actually touch the hull. It was over an inch away on each side in front of the seats.  That made it hard to tab in.
