Deck Support Ideas

After ripping off the deck and seeing how this boat was constructed, I'm really surprised at how shady it was built.

This is my first tear down and rebuild and I'm scratching my head wondering a few things and if you guys could throw out some ideas (pictures or a drawing) that would be greatly appreciated. Here are my questions with pics.

1. Deck support braces, they notched out the stringers and just layed in a 3/4 x 3" that just rest to the edge of the hull and supported the main deck on the boat. Would you do this again? Just seems really hard to glass the notch in the stringer? or to glass it all after?
1a. or notch the stringer and then glass the underside of the support and use PB (peanut butter) to glue it into the notch and then glass over?
1b. Make stringers out from the mains to the edge of the hull, maybe double up if this is to support two plywood deck seams

2. This boat has only 4 stringers 2 come off the gas tank area and go to the AFT other two from the top of the tank which forms the ski locker to the bow. Can the two off the back be glassed into the transom? Don't have a picture, the factory build stopped the stringer short and just put in foam. I was thinking of extending the bottom of the transom so I could tie in the stringers and save myself the extra void. Are there any structural issues doing it this way?

3.what is the general consensus to building new stringers. I was thinking of running string lines from bow to aft and across the width and measure down every 1' or every 4" when the shape changes quickly. then transfer these measurements to pink board. Is there an easier way?

4. Since this boat was built in 1995 and they only glassed 1/3 of the way up the stringer and it somehow made it to 2019. Would I get away with just using 1 layer of CSM on the top?

5. which brings me to my next question. Could I not get away with just PL the deck down without screws penetrating the main deck stringers?

6. While removing the Transom I noticed some really hard stuff at the top that feels like bondo, it's grey in color and looks like it's there to join the hull to the cap. What is this stuff? On the exterior they just used silicon.

7. last Pic is my current status. So sick of grinding! I'm almost done...is it absolutely necessary to grind back down to the original hull or is it okay to have most of it out? there are some areas I don't think that needs any crazy sanding, like where there is foam only and nowhere near any joints.

8. Last one. Ski Locker. The old one just has 3/4 ply strips glued and carpet wrapped all the way under the cleat. I was thinking of making a 3/4 frame (one piece) with a 45 bevel on to ease glassing and just glue it with PL and then glass over. What do you think.

Thanks all for reading and looking forward to some feedback.

Just realized I didn't leave a legend on one of my pics and couldn't find how to edit my last post. Here is the revised picture.

Ok I’ll give it a go ..

1 - probably not .
1a - will work .
1b - Even better but probably should drill weep holes in the bottom corners .
2 - Yes . No issues but needs the same weep holes usually ..
3 - That method works good .
4 - Yes but I would prolly put 2 ..
5 - Yes but I would use thickened resin and not PL . Make sure you seal the underside of the ply with at least a layer of csm before installing .
6. - It’s grey colored goo that they probably glued the cap on with . :joyous:
7 - You just need to get down to clean glass wherever new glass is going back in . Unless you just love grinding. :rolleyes:
8. - I see no problems the with doing it that way .
9. - That’s a lot of work so make sure the frosty beverage cooler is near by .... ;)

Sounds like ya have thought things through pretty well ... Carry on and let us know if we can help !

Thanks sphelps for the suggestions

Does anyone know what and why that grey goo is or what can be used to replace it?

Last night I dropped the cap to get measurements for the floor height and I had a heck of a time trying to get that cap back on. Went to home depot and got some threaded rod to try and keep the hull at the correct width.
Boy! do I hope it doesn't screw me at the end when the cap goes on for good.

Do you have the hull supported good underneath. Put some temp bunk boards under the outside edges and chines .
‘When the boat structure comes out it will move around and spread out . You don’t want to glass back in crooked by accident ...
