Gunner,
I am not a very knowledgeable fellow but it is my understanding that
snagboats were developed to remove trees and other debris from the river
channels that were "snagging" the paddlewheelers. These obstacles to
navigation were usually found in shallow channels and after high water or
flood conditions. They were simply workboats (paddlewheelers) of shallow
draft with a derrick affixed to the bow. The object was to manuever close to
the obstacle and "snag" it with a rope, cable, or whatever and drag it clear
of the channel. The derrick would be used to lift the log or stump, etc.
sufficiently that it could eb moved.
I ahve a book "Perilous Journeys: A History of Steamboating on the
Chattahoochee, Apalachacola, and Flint Rivers, 1828-1928", by Edward A.
Mueller, copyright 1990, second printing 2000. The book is published by the
Historic Chattahoochee Commission. If interested, I can provide an address
where you can ontain the book. As I recall, it was about $30.00. It is a
wonderful source of SE riverboats and full of photos and a few drawings in
addition to an interesting history of steamboating in that area.
