Strongback use

[boatbuilder]

I got my BSR 15 #145 turned over and placed on the strongback. I leveled the hull side to side and have the bow the recommended six and three quarters higher than the transom where the sides attached. I plan to raise the strongback on to blocks to prevent movement but my question, is it recommended to now attach the hull itself to the strongback or just let the weight of the hull hold it in place?

Attaching is probably not needed, although I have lashed a hull down to keep it from moving while working on it, or lashed it down to coax a twist into proper alignment. Drywall screws temporarily tacked to the gunwale, or a clamps on the gunwale serve as lashing points.

Thanks for the idea. I think I will hold her in place with tiedowns until the weight builds up.

With a square and plumb hull you can use level on various elements of the build. If the hull is just resting on a cradle it'll move, you can bet on it. One solution is to dog it down and drywall screws do well for this, but you could just mark the hull too, so if it moves you can smack it back into alignment. I don't know how much room you have but, many find it handy to have the cradle on wheels so you can move it around the shop as needed. If you do dog her down, I don't like the idea of straps (ratchet style assumed) as it can introduce twists and distortions into the boat. A simple scrap of plywood at the transom to the cradle and maybe the same at the bow will keep it from moving around.
