sorry for my lack of explanation.

here you can see the larger circle which i believe is the stringer.
problem is thats where the original patch is underneath. the fiberglass on top is not completely attached to the boat, its pretty flimsy if i lean on the boat the stringer sort of shifts and the fiber glass raises off the bottom, so i assume its lose, so i have to cut it a little, i have to some how get the riser up. to get to the bottom of it so i can patch the hole properly.
previous pictures show the patch/larger hole from the bottom of the boat.
the 2nd circle is another hole pretty small but needs patching i assume i sand a bunch and then patch it up both sides with epoxy? i want lots of strength here as i dont want to open the floor again
the arrow also shows a cut in the wood that does not reach the side i assume the PO cut it to patch but the stringer is also missing half... so ill have to replace this or brace it.
