Beautiful Signature Edition!

No, the dehumidifier is not a viable option. Theres just no way for the water to escape. Ive seen boats that were stored dry for years and theyre still soaking wet under the floor.

Not polyester. EPOXY.

I strongly recommend getting the engine pulled- it is going to save you a LOT of time and struggle when it comes time to rebuild that floor.

If you are dead set on removing the foam from inside the stringers, I would only pull the top off them- that way you wont have to create a mold to pour foam back into the stringer cavity before reglassing it closed.

It looks like youve cut up the floor in the front (sandwich construction) beyond saving, bummer. I would go back with a coosa floor throughout. That is the material shown above in Joe's boat, and is what we used on our Barefoot Nautique.

+1 don't go thru all this work then cut corners on resin. Epoxy will adhere to all other resins too,poly will not. Being in Canada changes things but check out US Composites

Holy cow! Look at that composite boat. I wondered what mine would look like if I had cut out the entire floor. Now I know. How wet was it? Interestingly, the foam in the tree-killed boat was mostly dry. There was a little water on the bottom of the hull, but that was basically it. You have put in a lot of work there. +1 on removing the engine to make things easier on yourself. Once that big hunk of metal is in the way it is odd how small the boat suddenly feels.

Please keep us up to date on your progress.

Can you tell me why you want to remove the stringers? There is nothing wrong with them.

I wonder what that blue foam piece under the driver's seat does?

I think he wants to remove the potentially wet foam from inside the stringers... no way to do that without cutting them open. I'd extract it from the top if I was so inclined- no need to remove them entirely (I would probably leave them untouched!).

What appears to be foam in the floor cross section is no doubt serving to build thickness and rigidity- that sandwich construction is how they built up enough strength for that part of the floor to span the open part of the bilge (25" wide).

Tim,

Thanks for the clarification on the dehumidifier option. Wet foam is not something they I've had to contend with on race boats. It must slow draw in water (osmotic?) then trap it in a closed cell.

I happen to disagree. Put a wet sponge in a couple of "baggies" and see if it will ever dry out. Do you even use a moisture meter?? They work on foam too!!

Hello everyone,
To update, I had great intentions of working all winter on the boat and it didn't happen. Currently I am 90% done removing the foam and floor. Generally just prepping to refoam and glass. With the help of another member via private message I have started a material list from US composites but would really appreciate the input of those experienced so I order the exact materials and amount. I'm from Canada so don't want to screw up the shipment.

80lb kit of 4lb density foam
2 gallon plus 1 gallon kit (total 3 gallons) medium epoxy kit
20 yards of 17oz biax 50"(includes floor and tops of 5ftx1ft stringers cut open)
3 rollers

I am unsure which biax to use as there are a couple types and the original floor seems to have a top layer of strand and lower layer of woven mat cloth...I want to keep it as close or better than original.
I also have a 2x4 area in front of observers seat I have to cover with either marine plywood or coosa.
I could also call us composites and describe the job, anyone done that with success?
appreciate the help!
As suggested previously I will get some pics out, first one being when the floor prep is complete.

I wondered what had happened to your boat. Sounds like you are ready to dive back in. That is good. I'm sure somebody here can give you good information on what type of mat is best. I only did a small repair and didn't worry about it too much.
