1981 stringer repair

Just finished getting everything out of the hull with the exception of the steering cable. I have snapped a few pics. During its life someone apparently attempted a scab repair to the secondary stringers and made a bit of a mess of it. I have read the other threads and have a couple of questions.
My plan is completely remove all the wood and replace with new wood and foam like it was originally.

1. The floor(deck) looks like it is good shape and may pop up in one piece after cutting the edges. Can this be re-used? It seems it would be OK if I sanded and sandwiched it between new glass mat it would help reduce the cost.

2. What is the dimension of material I need to search for the stringers 2x8, 2x10, etc ....? I can not tell from what I can see.

3. There seems to many thoughts on the amount of cloth. I prefer the long strips along the fore/aft line. Best type of cloth and width schedule for layup?

Thanks in advance, Rex

Rex,
Strip everything down to the bare hull. I think you will find there are big problems under the sole (floor). Don't forget the wood in the transom. Get it out as well. From the pictures, it looks like a PO did a hack job and laid a new sole over the old rot. Do NOT plan on reusing any of the old. Read the great threads on stringer jobs here on site. Ask questions when needed.

Keeganino I just went through your thread (3rd time)!! The primaries you went with are 2x8x12 Douglas Fir and the secondaries are 1x6x10 Douglas Fir? Is that correct?

Sorry for so many questions and thanks for the help.

That sounds right. I could not find it in my thread and my invoice for the wood I bought is safely tucked away! Was definitely DF and very pretty. I am pretty sure that there is a detailed materials list for my epoxy and glass order. It is just a matter of finding it in the thread. Of course your boat is bigger so the numbers are not going to be the same. Yours is a Ski Nautique? Mine is a Skier which is only 16'.

Yes, Ski Nautique, I can pull the floor and measure the whole length. I did see the thread with LVL. I would prefer Douglas Fir but will keep the LVL as my secondary if unavailable or cost restrictive. I am not to worried about the glass/epoxy as I have a local yard that will sell wholesale to me.

Just did my '85 a couple years ago so let me give you some tips?
1) Take one side out at a time that way you have a reference for height, length, shape, so on and so on.
2) Get a 4" masonry diamond wheel for cutting and grinding along with 4" 3M 24 & 36 grit paint buster discs for grinding and sanding.
3) Remove the foam in blocks with a hand saw and wonder bar.(save a huge mess)
4) This is up to you; I stopped removing the floor at the end of the stringers then hollowed out the wet foam from under the bow. This saved a lot of money in glass and time in rebuilding the air box. The wood floor stops at the battery box you'll see.

This is the start


Removing the foam in blocks (easy peezy lemon squeezy)



One side removed using original side for reference


Final framing "NO FOAM" going back in


Final product

If you need to check stringer sizes I have them drawn up in my thread... its the same hull but pre engine cradel so you just need to copy what you have now around the cradel.

Good luck with your build.

Roger, that CAD file may come in very useful for me if those stringers are the same shape on my 82 tique..

Yes it's epoxy floor paint it has held up extremely well.
It will be back together one way or another in the spring hopefully with a stroker.

Wow, that looks amazing. I hope I never have to do this on my '92

Got the floor up. Not very wet underneath. The scary thing the entire secondary had less 5% wood left! Got out all the foam on the STBD side. Thanks for the tip with then hand saw. I am afraid to go any further on the PORT side until things are repaired on the STBD side. I am going to replace the secondary stringer, then remove the primary and replace it. Here are some pics of with the floor up and the "job super".
