I was looking at the history of the Confederate States Navy and found that their primary Ship building center was what was eventually renamed the Gosport Shipyards (renamed the Norfolk Shipyards in 1862). The Union had controlled it at the beginning of the war, but when they abandoned it, did *not* properly destroy everything. For example, the hulk of the USS Merrimac became the CSS Monitor.
If the Union manages to properly destroy everything, it will cause a smaller CSA Navy (the only other ship building location was in Pensacola).
Does anyone have any idea on the effects of the Union Blockade being *more* effective? Are we likely to still get the CSS Alabama, more ships similar to her, or less?
