After soaking for a couple of hours, the planks easily bend to the proper shape. I can do two planks at a time on this. The bending iron will be needed to bend the planks around the bow, which I suspect will require some experimentation to get right.
Your edge bending set up is well done and a great example. You mentioned a bending iron for the broad bend but there is another way that gets the amount of bend exact. After you remove it from the forming jig and taper the breadth of the plank re-wet the wood at the bow end and then clamp it in place on the hull. Dry it with a hot air gun or even let it sit to dry if you don't mind waiting. Remove it then glue it in place. Just another way to skin the proverbial cat.
