Is this normal or is there a problem?

I have the sides wired, the forward bulkhead installed, the temporary bulkhead installed and the transom installed. The sides flair out too wide for the temporary bulkhead to be wired at the sides. The measured beam is 6 ft 5 inches instead of the 6 ft 3 inches per the plans. The extra 2 inches of beam is equally divided between the sides with about 1 inch of space between the each side and the edge of the temporary bulkhead. The center cradle support is 1 7/8 inch below the other supports, so I do not think that I have too much rocker in the hull causing the additional flair. Is this extra flair normal at this stage or is there something else wrong. I understand from reading other post here that the inwale will help to bring the sides into a fair curve, but will it help in this situation.

I should have indicated that I am building a CS 20.

I think that the inwale will solve the problem. When you pull the sides in to the center frame you probably have a bulge on either side of the frame. The inwale will fair that through the length of the boat and it should be fine.

I hope I am reading your concern correctly. While sides in a newly formed hull is a bit flimsy, your molds could also be even one inch or so either way with the continued curves going foward and aft depending on your location of the particular one, causing the space between the mold, also. While placing the inwales will help compress the sheer of you hull structure, its also important a check at the chine line, making sure that there is also a space at the mold. If not, you may have a dip or an indention in the hull sides. Try to sight along the chine area, the joint along the side and hull bottom and also run your hand along the concerned area, and see it it flows a uniformed curve.

Also not all woods bend the same, either, Its more important to let your wood tell you a fair line, than some measurement that is also etched in stone on any plan. People cut outsides of measured lines, also causing some deminsions to change in the actual build. .

Also in some cases, the fore and aft blocking along the keel line, can also cause some excessive spacing in the middle of the stitched hull, kinda like if you cupped your hand creating more rocker in the hull. This translates more flare out in the middle part of the hull.
