Sheer Clamps

You can attach the sheer clamps to the transom and bend them around to the bow (my preference), or you can attach to the breasthook and bend to the transom. Either way, bend the two stringers at the same time. Otherwise, you will put too much stress on one side of the boat and possibly wrench it out of wack.

Stress from this bend caused a distortion along bulkheads three and four and the transom (see picture). I solved this by placing a thin shim (1/8" - 1/4") between the sheer clamp and the bulkhead. Use whatever thickness does the job.

Use three or four screws (and epoxy) to attach the sheer clamps to the breasthook. Expect to remove them later so that you do not run into them while beveling the framework.

One screw will suffice at each bulkhead, or you can simply clamp them in place until the epoxy cures.
