No problem! In the meantime the answer to your basic question is yes, the crosspiece does have a crown to it and the support that goes from it to the tip is also bent. It curves up to match the sweep of the rails. This piece is also slightly beveled on top from center in both directions so the two deck halves will land flat. The end result of the crowned cross-piece and upswept center support once the deck halves and center trim are in place gives you a deck that curves up to the tip parallel to centerline and curves down to the rails at the combing.
