As Robert said, the Tamiya kit's hull is split at the bow...it was obvious that the kit was designed this way to fit into a smaller box.
Trumpeter's 2 carrier kits, Hornet and Essex, are split at teh waterline, you can build it either full hull or waterline. The fit at this seam is good, easily filled and sanded, and both models I've seen completed, the modeler used black decal strip for the boot topping that covered up any trace of a seam.
