If totally sealed condensation might be absorbed by foam, after 50 years.
If drain holes are drilled water will get in and might be absorbed by foam after 50 years.
If all wood is sealed, bottom of floor wood, key hole for drive, speedo pilot tube, tow eyes, etc. it should last at least 50 years.
Think you'll last 50 years Mike ... LOL

I feel lucky and privileged to have made it past the first 50 mark, so I'm kinda doubting another 50 to go is left in me.

Guess I'm just saying ... Lasted 25 years done half azzed ... Should last 50 years if done right ...
Pro's and con's with any method used, so it's what ever idea sounds best to you.
Hope ya last another 50 years Mike ... I hate funerals !

If there are no air cavities, and its sealed foam, there's no air to condense, so a permanently sealed & foam filled area shouldn't 'get wet'.  I think the only issue is making sure that it stays sealed.  No cracking, no separation, no way for water to get in.  Our boats are low enough that wakes/waves can get in over the bow/stern/sides...and sometimes you get caught in the rain too.

So...if you're going to seal it up, the underside of the floor has to be sealed, essentially everything so water can't wick up via the wood into any sealed area.  If you do a good job, no reason it shouldn't last for decades.

Option B is to keep it all open enough than you can open it up and leave it to dry out fully.

I think they're both valid options.

I think even the small amount of condensation from small voids in foam, won't amount to enough to cause problems.
Just one of the con's I've heard stated about sealed floor.

I suppose heavy abuse could crack the stringer or bulkhead allowing for a gap that water could find its way in, but even then it is foam filled and will require long term contact before much absorption could occur.   As for any gaps, I plan to pour foam until nearly full, then use some of the softer "great stuff" type foam moments before gluing and screwing the floor pieces down.   As for the floor pieces, I just finished putting a cloth/resin layer on the entire bottom of the floor.   Once glued and screwed, I will sand, treat, peanut butter all gaps, then treat, add 24 oz woven roving to the floor to hull perimeter, then cloth/resin layer overall to make smooth and waterproof.  Seems to be the front runner in my interior design to make a painted/ruff deck surface so its easier to clean and moisture runs off to the bilge.

This sealed/not sealed cavities is turning into another plywood/marine plywood "discussion."

No air space every screw dipped in 5200 and glassed over. It was a big decision for me weather to put the drain in or not

The hull is mostly complete, sealed, tabbed, and covered.  Time to flip and correct the bottom issues.

     Cant get anything past you folks, you are correct, there are no motor mounts.    The Timi mounts are considerably taller than in a CVX/CVZ application, I assume due to a higher X dimension?   Maybe Tim or someone knows.   Regardless of why, I decided to design and build a custom machined mount that will spread the load more evenly, and not occupy as much area on the sides of the engine.  For now the bottom is essentially completed until I work the top and marry the two back together.

Nice thinking on the motor mounts. Honestly I really didn’t want to just lag bolt my engine mounts back in even though sealing them in and stuff will out last me. I really wanted to make an aluminum channel glued in or something along the whole rear part of the stringer. Over building these old boats with new technologies puts a smile on my face.   
Very nice work so far thanks for sharing.

Hull has been flipped, cleaned, degreased, and one side has the ablative coating(black) sanded off.  Since the photo was taken, I've stripped it down to gel coat, and took measurements.  The designed Hook is on the outside and measures out at nearly 1/2".  Other than a moderate case of boat pox, scratches, and a couple previously poorly repaired spots, it appears to be fairly solid.  I'm currently about halfway through grinding out the blisters.  Once they are all opened, a nice hot water bath will remove any remaining residue from the blister.  The ground out areas will then be filled with epoxy fairing.  When complete and smooth, the bottom will receive 3-4 coats Interlux interprotect, followed by VC performance epoxy.

Are you removing the hook or changing the X dimension?
I think this has become an addiction.
