Now that's using the old noggin. Very clever idea that I hope future builders will see and repeat.

Thanks, I'm pleased with it, too. Anything to make bilge pump management easier.

That's a great idea! Homemade gasket. Perfect.
Whale Supersub low profile pump. 1100 gph. They make one with a built-in sensor, but while Whale pumps have a decent reputation their sensors don't. Thus I'm using the plain pump and a Johnson sensor.
Been doing some upland training with my lab the last few weeks and helping my bride after breaking her wrist (fall on ice) so have worked very little since my last post. But figured I better do and post something after the shit I'm catching in another thread.
Several comments on sole support. I really didnt want to create air pockets by adding longitudinal runners, but after thinking about it a bit realized a couple ribs on the bigger sole pieces would add plenty of strength and rigidity without boxing anything in - and made good use of some waste.

Nice! That is a great solution which will make a world of difference to the rigidity of those pieces when stood upon.
What’s the reason for not wanting to create sealed air pockets? I joined some of my compartments by drilling holes through the stringers/keelsons then installed a combination of deck plates and drain plugs so that the sealed sections could breathe when the boat is stored or not in use.
I’ll shoot some pics tonight.

You do such a nice job. Makes me jealous, and envious that I don't have a heated work space for wintertime.
Between high humidity and temperature swings, I worry (probably too much) about condensation and, thus, captured water in sealed spaces. My below-sole space has large limber holes front-to-back so any water can exit easily - and as large as I felt I could make them and keep structural integrity in their parts to maximize airflow (I'll probably also remove the access covers when not in use). I think as long as you have a way for moisture to drain and/or evaporate, you're good.

Here's what I did. I'm not worried at all about condensation/captured water (maybe I don't worry enough -- I do worry about weight and strength however.)
I drilled holes to join some of the under-floor compartments into 7 individual zones. Each zone has its own breather in the form of either a deck plate or bung-style drain plug. When the boat is not in use I will have all the breathers open.
I still have to buy and install the drain plugs for zones 2 and 3, which will be the same style as no.1

I use similar deck plates on my Brant. They have a couple issues. 1) The threads get sand/dirt in them making them very difficult to remove. I keep them as clean as possible and made a wrench to open them. I only hand tighten them. The wrench has lugs that fit into the depressions in the top and when turned press against the piece your hand grabs when opening/closing by hand. 2) If you or your hunting partner steps on them dead center with much weight they will crack. I resolved this issue by cutting out a plywood disk and epoxying it to the underside flush. An elephant could stand on them now. Your CNC skills should allow you the ability to make a perfect fitting "plug" to the underside. I can't quite tell but it looks like yours have depressions on the top. Mine are the opposite. You may need to plug the top side.

Looks like you have it well thought out.
It is common for water to "magically" appear within chambers. I believe that every Devlin designed boat that has ever appeared here over the past 20 years with significant rot damage has been linked to water infiltration inside chambers. In the old days when making them sealed was the standard I believe this happened because they pressurized and then suctioned water in through an orifice. It has also happened in boats with access plates too.
Water has a way of getting in, that is why Devlin says to build with premium marine ply which is better for a number of reasons.
