You are a kook. It is one ship. How many did New York control? Thousands?
Do you think 1 = 1000? What is wrong with you? You don't disprove anything, you only prove that you are some sort of kook with claims such as this.
Totally irrelevant, since what matters is the ability and capacity of Southerners to build, own and operate their own shipping if they wanted to.
SS Planter proves they could, and makes your claims a lie.
The fact is that you have no idea how many ships were owned and/or operated by Southerners, and it doesn't matter, so long as some were, because those some prove it could be done, if they wanted to do it.
