Am seeking information on the so-called GUARD system of circa 1880
sternwheeler packet boats (like on the Mississippi River cotton
haulers), specifically info on those large vertical members affixed
flexibly at their top end, and which can apparently be moved this
way and that at their bottom end. These were spaced every 15-20 feet
along the main deck and hung down to near the waterline. I've seen
different numbers of these "things" in old photographs, depending on
the boat in question there may be five per side, or ten, etc. PLEASE
HELP, THIS IS DRIVING ME NUTS!
