UPDATE:
It has been a while since I have done much with the sailboat restoration. So, today I decided to flip the boat back over and begin working on the upper hull and deck sections.
I hooked up the straps that I used to flip the boat originally, but this time made sure I had the boat plenty high enough. I also did not wrap the straps around the rollers as that seemed to bind up pretty bad last time. I also had my blocks and stands to 'catch' the boat in case it fell or something like that.
Anyway... I got the boat tilted up to about 20-30 degrees of the total 180 degree rotation, and as I was making some adjustments, the boat decided that it wanted to roll all by itself . . . AND BOY DID IT

within about 1 second elapsed time it rolled over on its own taking everything in the way with it. Talk about VERY EXCITING

Not much I could do since it happened so fast, just get the heck out of the way . . .
Here is where the boat ended up . . .
Fortunately I had the boat raised enough and the straps tight enough that the hull did not bottom out as it rolled over. It was suspended up off of the floor by about 2". It did catch a block or something as it rolled and it snapped about 1 foot of the rub rail off, but that should not be too bad of a fix.
I finished righting the boat and am going to prep for putting it back on the trailer.

In terms of next steps, I had considered ways of restoring the foam in the aft berth chambers, as the foam is still pretty wet and crumbly even after sitting in the garage for a year. I also need to do some other work in the stern section, but the access is more child size, given the size of the boat.
I think that I am going to separate the deck from the hull, since it is a sandwich design and held together primarily with staples. I removed a section of the rubrail backing strip at the stern to see how easily the hull and deck pieces might come apart.
I also checked the inside of the boat where the hull and deck meet, and that looks like it should come apart OK as well. Here is a picture of the inside seam.
It looks like I could separate the boat havles . . . it would be a bit of work, but do-able. . . Plus, I already have 1 foot of the seam separated with the piece of rail that snapped off
Anyway, there are staples about every 4" all the way around the boat and the rubrail backing (what you see in the picture of the 1 foot broken section) has staples in it too. So, that is about a bazillion staples . . . but I think I will have a much easier time doing the restoration work on the inside of the hull.
Almost like rebuilding the boat, but it should be good for another 40 years.
Thoughts, advice ?
