I joined the second float over the weekend.
I screwed a batten to the top of the mould along the keel and deck C/Ls which makes the top half captive when it is being glued. The ratchet straps apply pressure and the top half tries to spread but the extra battens limit the movement and this effectively aligns the two edges. Pick below of the sides strapped together.




Once the resin has cure the hull come out and I fill the rebates in the foam for the newest side. The reflection of the flash on the different surfaces fails to show how incredible fair the hull is given the construction method.
I will still take my time preparing the external surface as best I can before the outside laminate is vacuumed on.
