Boat Builder Central

Thanks for all of the quick replies! I do have the baseline drawn on the frames and the stringers match the baseline. I'll have to wait til I get home to give exact measurements and attempt to upload pictures. I'm pretty sure my measurements are accurate.(Marine plywood is expensive!) Thanks Jacques...

This is my first build and I am having a problem with frames A&B. The bottom of the frames are not flush with the bottom of the stringers.(About an inch too shallow on both.) I have remeasured several times and the measurements are correct....1" from the baseline of 8 3/4" on the frame...
