So I purchased a 69 191 hull and trailer from a friend of mine with plans to put a floor in it and a few more things. I loved the lines of the boat and had to have it. After removing the floor and seeing some of the boats that have been redone I decided to rebuild the whole boat down to the factory hull. I know its a heck of a project to take on. I dove in head first and started the demo. I should have researched a lot more before I started. I feel like I've gotten in over my head sometimes I'm going to post some pics from the beginning until where I am now. Any advice and help will be much appreciated.

doesnt look like you did anything to detrimental to me. Console prolly needs to be re-glassed anyways and with the floor coming up follow guidance from some of these guys. They are way over my head in capabilities

The transom was in really rough shape so I cut it out an plan to glass it back in from the inside with a mold

She's a beautiful blank canvas. I have benefited greatly from hours of reading and re-reading the build threads on here. There are some brilliant minds on here that have all been there before. If you have any specific questions, fire away. Somebody here will be able to help.

OK so I know now I should have rebuilt the boat in stages to help keep everything in shape. Also I took the cap off and cut it up because I knew I wanted a custom cap that could be walked on. Should I have kept it for a pattern. The boat has been redone before and the inner skin was cut out. The boat is very flimsy with no transom stringers or cap and I'm worried it will loose its shape. I guess my main question right now is have I ruined it ? The sides at the shear line are very wavy. Should I get it on stands and square everything up so I can work on the transom. Whats the best way to do that if thats the next step.

I don't think you ruined anything, but I would see if you could take dimensions (or talk somebody else into measuring) from an unmodified boat of the same model. If you can find dimensions across the top at multiple points, and the proper angles of the bottom and hull sides at the transom, you could support it in some temporary frames to hold the correct shape while you rebuild it. I certainly wouldn't throw in the towel.

That's what I was thinking. To build a temp frame and stands to support it during the build.
No I'm not going to through in the towel. I keep thinking about what I'll have when its all done. It's a lot of hard work but hopefully most of the dirty work is over.

Definitely not a lost cause. Just take it a step at a time. Get some cradles built that support the hull without twist or hook in the bottom. Then get your transom built. Make sure it is symmetrical and maintains the original lines.

After your transom is installed, double check that nothing has shifted and your hull is square. Then laminate in your stringers. Finally, make sure that you get fair curves when you build your cap.

This skips lots of steps, but outlines the key things to consider when keeping your hull’s shape. Would it have been easier to take the demolition in steps rebuilding as you go? Yes. Can you successfully complete this rebuild? Yes.

As you mentioned, someone had redone the inside of the boat - definitely not even close to factory.
You have received good advice already. Get the hull in some kind of cradle to maintain it, grind the inside all down (up the sides too), get the transom in and then lay 2 layers of cloth (1708) on the inside overlapping in the center of the hull and at the chines. You can buy cloth in different widths - 50" will give you the width to do the bottom with overlap and then cut the cloth in width and that will do the sides. When done you will have a stiff hull and then can start your rebuild.

Here is what I did on my hull

Hang in there - get the hull stable and then take it a little at a time.

Thanks for your comments guys. So does anyone have measurements from an unmodified or modified 191 that I could go by. I took a few measurements before the demo but factory ones would be nice to follow. I plan on building a cradle this weekend and getting everything squared up. Next would be finish the grinding , installing the transom then glassing the inside and up the sides. It's hot here in eastern NC right now and I'm glad to own a shop to work in. As for material with proper preparation would good quality polyester resin and marine plywood be sufficient for this rebuild. I want it done right and to last for many years (25yrs) but don't want to over kill it and break the bank. (marine plywood transom, stringers,cap etc) Or are there better choices without to much cost. Any holes would be epoxy filled then drilled. I've read the arguments about epoxy vs poly and it gets confusing. Also I plan on gel coating the boat inside and out.

Plans are to close in the transom and put a 150 4 stroke on a bracket. I've heard a lot of talk about Blue Agave's boat. Where can I find some pics of it. I did't see it in the members gallery.

The down and dirty on epoxy is it's secondary bond is 2000 times better than the secondary bond with poly. So that means sticking something new to something old.
I did the transom of mine with marine plywood and did everything below the sole in epoxy and everything above in poly. All the structural stuff was done with epoxy. I did the upper in poly so I could gelcoat it.

There are plenty of rebuilds done with poly and they were fine - it's a choice thing.
