I, too, have watched the declining fisherfolk population in Hong Kong's
Aberdeen Harbour using single sweeps - also didn't know the proper name is
"yuloh" - on their cork-like bum-boats to great effect.

However, for real excitement, try Bangkok's canals where this technique has
been adapted to modern technology. A 4 cylinder car engine is mounted on a
steel "yuloh" directly above the gimbal on the stern of a very narrow boat
at which point the "yuloh" becomes the drive shaft and turns the prop
directly. No tranny, or reduction gears. The boatsman cranks this thing up,
and off you go at remarkable speed with the driver steering by moving his
end of the "yuloh". It's scary to think of the possibilities...

Cheers, Garrett

I realize that picture attachments are not allowed on TWL. However, I
seem to have too little imagination to picture a Yuloh from the
descriptions given. Would really appreciate if someone could send me
a JPEG of a Yuloh, off-list of course.
