Don’t do it! Plywood sucks up just as much moisture, expands and rots just the same, albeit a little more slowly. I had the plywood in my old trimaran get totally wet and delaminate. Terrible. If you are going to avoid balsa and you might do so for good reason, order up some CoreCell or Klegecell. Coosa might do the trick really nicely. Make yourself a big list, order it all at once and have it shipped to a depot. Then, with a boat or a truck or whatever will do the trick, get it all back to your yard all at once!
All this work and you don’t want to be remembering the compromises you made!

Balsa Core $50 - Shipping to Alaska $131.
Coosa $141 - Shipping to Alaska $167.
Corecell $93 - Shipping to Alaska $110-224
Baltek At Amazon - Wont ship to Alaska… Considering dumping Prime (Becoming more common)
Arrggg - And now you see my curse. Go find a bunch of moose antlers, tie them together and epoxy in place…
I bit the bullet and bought a 2x4 section of Balsa.
Today was dry fitting a pair of mock up Trojan Deep cycle house batteries. Only 210-amp but shall last for a while until lithium come down in price - I hope.
Preliminary wiring of batteries. Still need another cross member for the forward battery then straps over the tops. I left my 2x4 cedar out and after cutting the first one it started to rain.
The bottom fuse of the power post is for critical circuits. The remaining go thru the switch. Wire is Arctic Flex 1/0.
Once I get it how likely it I will put fire hose around chaffing areas, seal the voids and place a vent hose in the mix.
FYI - I have 1/4" (3-mm) of clearance between the top of the wing nut and the settee plywood.
House batteries are in place. New tops for starboard settee done. Not screwed down completely since I still have more wire to run and I need to vent the battery space.
I did pull the 1-1/2 hose running from the head sink. Will reroute it to the head seacock since that is not being used anymore (composting toilet). Still waiting on parts to complete the 120-v.
More rot but not surprised. All the stringer on top of the fuel tank were shot. Two are in place. 2x4 cedar cut down to proper height, ends soaked in epoxy then bedded into a mixture of thicken epoxy with 406.
The section below the oven is shot. Looks like the port light leaked for some time. Will deal with that at another time.
Today I cut out and recessed the C-head. Will trim around cut if I am ever allowed a trip to Anchorage. COVID-19 has made getting certain supplies a pain.
GAt some point soon you need to create a thread titled “and it ends”
cause you are just jamming along. You said your stingers are cedar. Did you epoxy coat the whole length or are you relying on the natural rot resistance? Mine are fir and are obviously fully encased.
Sorry for the lack of updates. I was recently diagnosed with a medical issue that had me on some pretty crappy medication. Out of it for 3-weeks. Had to stop the meds due to the side effects and am slowly getting back to things.
A new Dickinson P-12000 was installed except I could not get the actual propane hose yet. I will add a few photos here.
Winter is coming for us. Snow on the mountains so I am refocusing my efforts to winterizing the boat. Will work on projects throughout the winter yet I also have to refocus on some medical issue.
