I think 1 sheet of 3/4 marine ply ($120) will do all the stringers. if memory serves me they are 3 " wide. I think I stack 3 pieces on top of each other. dont waste your time or money on the hard foam from homey depot it has no strength at all.

Thanks Billy-- sometimes it better to be lucky than good. Hopefully the fiberglassing comes as naturally as the grinding.... Did you use "last a foam" its the only foam I can find in 2" width. Its a core material on fiberglass supply.

We like the flat deck as well. Boat feels much bigger with the casting platform out. Did you make your front locker water tight? The only down side seems to be water getting in since you loose the drainage channels.

Hi roomtomove. Looks like we are both about the same stage in our 20’ restorations. Did you leave the keel stringer alone? I drilled a test hole and found the wood core was soaked. I cut it open and removed the core which was saturated. It looked like a basic 2x4. Thinking of filling it with sea cast.

Paul-

The keel stinger was already removed when we got the hull. There is a hole on the keel (directly below where the stinger was), not sure if that is why the stinger was removed or if it was a result of the demo.

We plan on our laying some glass down and adding a PVC stinger/drain on the keel.

Looks like a good project would like to see some updates.

Got a little work done a few weeks ago... Closed the stringers up with marine ply held on place with CSC. Then we fabbed up some marine ply to raise the stringers. Bedded them in poly/cabosil putty. Filled the seam between the existing stringer and riser with poly/cabosil/milled fiber putty along with any other voids. Glassed it all in with multiple layers of CSC and 1708. We also got the old bilge hole patched from the inside.

We have been trying to do all wet layups, seems well worth the long days in order to grind as little as possible.
