are the correct?

I assume you mean the Union naval blockade.

In the beginning of the war, the Union's navy was not very effective. Ships could easily pass through the blockade; they became to be known as "blockade runners." However, over time, the Union blockade became more effective, preventing access to them (partially, but still effectively).

The South was never really a manufacturing power at this point in time, so they never had a significant manufacture of goods (at least compared to the North). That being said, there were not many railroads in the South for the reason just stated.
