The Alabama is indeed a revised Kearsarge, as Tilley notes, however it's a very good basis for a Kearsarge from 1864.
I have seen this statement made several times over the years, but I have never understood the reasoning behind it. The Kearsarge kit hull does represent the ship in the 1880s, but is also mostly correct for the earlier ship as well. The main visual difference is the height of the bulwarks, which aft of the raised forecastle deck should be cut down to the tops of the gun ports. This is a fairly easy modification for a modeler to make.
On the other hand, for the Alabama hull to correctly represent the Kearsarge, the head would have to be completely reworked, the forward bulwarks raised and a forecastle deck scratch built, the gun ports filled and new ones correctly sized and located for Kearsarge cut in, and the false stern windows filled in. In addition, the deck and fittings are correct, or mostly correct, for Kearsarge, while the deck and fittings in the Alabama kit are correct for nothing. The thought seems to be that since the Alabama hull already has lower bulwarks it is a better starting point for the Kearsarge, but in my opinion, if one wishes to build an 1864 Kearsarge, starting with the Alabama kit offers no advantages and many disadvantages. The best reference for the Civil War Kearsarge is Arthur C Roberts’ four part series of articles staring in the Dec 1999 Nautical Research Journal.

There will be some discrepancies that I am going to let ride, such as the hull length (11' short is only 1 3/8" difference at scale) and probably the tail, which I understand should be a clean curve. Now all I have to do is find one at a decent price.
Several years ago I posted a somewhat lengthy explanation of why I felt that the two ships were very close dimensionally and that the Revell Alabama hull was not far off in length.The full post is here:

but the short version is that, because of variations in the way British and American ships were apparently measured, for Alabama the Revell hull may be less than ½” too short.
