1352Re: pop-pop paddle wheel
- Mar 1, 2009Hi Pete,
We have an old (1947) side wheeler working around here called the
Waverly. The hull is very long and narrow. The wheels are on a
shaft with a horizontal steam engine in the middle. Talking to one
of the Harwich pilots, it is a nightmare. It accelerates very fast
and stops fast, but has no steerage way until moving quite quickly.
Turning circle is huge. All this makes docking difficuilt especially
in a tide or high wind. They have thought of fitting a bow thruster
or even a bow rudder, but there is a reluctance to mess about with a
ship this old. Will probably stay with a skipper with nerves of steel!
I do appreciate the lure of the difficuilt - why else am I messing
around with pop-pops instead of something more efficient,
conventional and off the shelf.
