Standard References on the Confederate Navy

I am gradually expanding my naval history library to include the Civil War.

What are the current, standard reference books on the Confederate Navy?

I recently acquired A History of the Confederate Navy by Raimondo Luraghi and Iron Afloat by William N. Still.

What, if any, other titles should I consider acquiring for my library?

Thanks in advance for your input.

You may want to consider James McPherson's War on the Waters.

Another good one is Two Years on the Alabama by Arthur Sinclair.
