Hi Mike, Walter here, regarding the use of paddlers in watime.
Regarding the ASCOT (sometimes refered to as RACECOURSE) class, most
of them saw very little use as they were completed too late for
service, and I am certain at least two were used as seaplane carriers
for two or three aircraft carried abaft the paddle boxes. Also post
WW1, two were converted for civilian use and made very handsome two
funneled pleasure paddlers. Names to follow when I can get into my
library (loft!). Also the US navy and French navy used many stern
wheelers in China some of which were captured and taken up by the
Japanese navy
The Polish navy had quite a few taken up for service on their rivers
and estuaries, including the only torpedo armed sidewheeler (a
rotating torpedo tube on the after deck !!) minelayers, hospital
ships, anti aircraft ships, command, patrol and several other uses.
All were sidewheelers and a lot were ex Russian. The Germans took
several of them into service. Can I suggest you visit
http://polishnavy.prv.pl/ quite hard to navigate, but plenty of
photos and some simple profile drawings.
Also, the paddlesteamer preservation society publish an excelent
small book titled HMS ARISTOCRAT. This gives the full wartime service
of my namesake Clyde steamer TALISMAN. This includes an armament
layout drawing, VERY difficult to find for British paddlers taken up.
Sorry this is so long, but this is a pet subject of mine. If you
want more, (like the Turkish FETH-UL-ISLAM) etc, let me know. All
the best, Walter (alias talisman)
