The forward most corners are about 1/2” from the hull so it is fully enclosed on the bottom.
The T section was placed in and references on the first rib which you can see in the pic. It is behind but screwed to the piece that makes up the bulkhead you can see.
This was important to have in place as you need the weight of the battery to keep the foam from lifting it out of position.
That is another reason for doing small pours, and also so you don’t wind up with a huge mound you have to cut down flat. After the foam cured I cut it flat/level with a power hacksaw blade. Then I put Luan plywood that was epoxi sealed down for a flat surface, then carpet.
ETA: Ran out of time earlier.
The NOCO is the battery box brand and it is not cut down, just buried in the foam. As mentioned the front two corners are near touching the hull and the rear two corners are probably 6" or so off of the hull. My charger is not in the pic but it rides to the right of the battery and slightly forward with my anchor, life jackets and rope.
I think I can sneak the battery out when/if I need to replace it without removing the deck. I think.
Ive also drilled and added a grommet to put the wires under the deck so their not exposed and finished (Mostly the floor since that pic was taken.
