[quote=dmgbear55]The last image is telling. The boat did get wracked pretty significantly as evidenced by the bending of the inside of the beam. That little bit of collapse made it nearly impossible to get the needed tension on the straps. I think you can make your hull repairs and sort out how to get the needed tension back on the straps when you are ready to put it back together. You can also shop for new replacement beams that are likely in better condition than yours are. New straps will also give you a better starting point, but are not absolutely required.
Part of your solution will be to rivet the straps to the beam regardless of whether or not you decide to keep the center tube or not (the tube that goes from just under the mast to rear beam). By positively locating the beam/straps/hull by riveting you can avoid a repeat of this problem and solve some others as well. But you do need to get the required tension back on those straps. Building the cradles up to raise the beam slightly, adding some shims to the underside of the straps, shiming the beam up and/or replacing the straps would all go a long way to getting that strap tension back to where it needs to be.
Again since you are going to be doing glass work to repair the collapsed area I strongly suggest that you also wrap some of that glass up over and around where the beam strap sits. Just grease one of the bolts and glass all around it. When the resin hardens remove the bolt and sand everything flush. A couple of layers of glass over these areas will save you another repair someday soon and maybe some unneeded excitement when you are sailing.
