Depends on whether it it a right or left hand screw of course.

Walking is more a natural function of how a propeller works
that has to be counteracted by a rudder to keep it from
having its way.

For example, you are aboard a right-handed single screw
vessel with headway on. The engine is put full astern and
the rudder hard left. The bow will first swing to the left and
the swing to the right as the vessel loses way.

The swing of the bow to the left is a function of rudder control
while the swing to the right as the vessel loses way is caused
by the prop walk overcoming the effects of the rudder because
of the decreased speed and decreased rudder control.

I hope this helps.

No doubt that cats under power with wide spaced twin engines are very
maneuverable under power.



Let's face facts; a Multi trying to manouver ( Over even making a simple
turn in tight quarters) is not a pretty thing. Even under power.

Skilled hands make light work under power. Juggling thrust can walk a
cat sideways and maneuver in ways that monos can only dream.


I'd like to see that. Theory suggests that with small props & rudders, prop
walk and kick aren't going to move it sideways much. In practice??

Interesting .... I'd have thought the opposite.
Since "walking" is highly dependent on rudder power and most sailboats
tend to have better than average power in this area and a "cat" doesn't
tend to have a great deal of wetted area and or windage (exceptions
noted), I'd have guess them to be good candidates for "walking".

Depends on whether it it a right or left hand screw of cours

Neal rarely gets either.

The discussion in question, was way over Neal's head and/or experience.

Why do you say that? Why did you decline to respond
to my post about the affects of rudder vs. prop walk
in the situation I described? Was it because you failed
to understand what was said?

This post, and the one, from you, which brought about my response, highlights
the reason for my response.
They were not talking about single screw "prop walk". They were talking about
making, or the possibilities of making, a twin screw boat "walk" sideways.
Your post was a dissertation on a basic "motorboat" maneuver, with a fixed
pitch, right hand propellor. (possible exceptions noted)
The fact you weren't aware of this and made your post, showed that the topic
was "over your head and/or beyond your experience".

Shen

Duh! Two fixed props spinning in the same direction
as on Jeff's catamaran will act the same was as one
fixed prop on a monohull.

You sure you're a licensed captain. You just aren't
too bright.

Snif? Snif? Smell the beginnings of an electrical overload, as Neal frantically
searches the web, looking for information on twin screw "walking"
