 Here's several interesting links on confederate 
semi submersible torpedo boats and the Winans cigar boats. 
This one is about an archaeological find of a David 
torpedo boat, possibly THE original David found underground in Charleston 
S.C. 
by ground penetrating radar. 
This one is a good site about the David semi 
submersible torpedo boats. http://www.charlestonillustrated.com/hunley/david.htm 
This last one is about the Winans cigar boats that 
the David torpedo boats designer's used the Winans hull design of. 
The hull design and early model circular amidships 
propeller (that was discontinued) is very unusual and interesting. The final 
model of the Winans cigar 
ocean going ship has multiple blade propellers both 
fore and aft and looks very futureistic for its time.
