Walking and rudder power are intmately related.

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.

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".

Hey Simple,

Thought you might be interested. This old man was very happy with the
safety lines I installed from the mast to the pointy end.

I could walk out to the head sail, this morning, to tie wrap the sail
for safety this morning. Works great.

I ran two strips of Webbing from the mast to each side of the Bow
Pulpit. I clip each line to the mast base plate when not in use. When I
go forward, I lift the leads from the plate and clip to Spinnaker Ring.
That way I can hook the safety line to the windward line.

This morning, I just used them for balance to go forward to tie the
furled head sail. When I was finished, re-hooked to the plate.

I wish now I would have rigged them years ago. I got a wet ass from the
storm but I didn't have to crawl like a worm on my ass to make it
forward in the blow. Think about them for "Mustard". They are really
worth the effort, if you have to work the pointy end in a Blow

AND; "I'LL DRINK TO THAT!!"

Sounds like a good idea. I even have a spinnaker ring so I
could attach them like you did. How did you attach them?
Did they come with snap shackles on each end? Are they
pretty tight when attached to the spinny ring?

And, what about them flopping around and flapping around
on deck when the wind blows over them? Do they become
a tripping hazard in light conditions when you're not inclined
to use them?

Simple,

I brought the webbing and clips and stitched them to length. I
originally planned on hooking them to the gunnels while the sails where
flying and just bring them inside when I wanted to go forward. After
using them, while working on the boat in the slip I found it easier to
hook them to the mast plate. They are a loose fit that way but being a
flat strap they really aren't a problem for me. I don't go forward of
the mast very often. When I do it is to hook the tack of the drifter or
the Spinn. and then I want them in place. As I head back to the cockpit
I drop them to the plate.

Neal, I really don't consider them Safety lines, I consider them Balance
Lines. I'm sure they are strong enough for safety line BUT I hope I
never have to find out.

The clips I used were 11/2" bronze. When It is calm and/or I have guest
or crew that Sun themselves on the foredeck, I disconnect at the mast
and send the ends down the fore hatch, to the V-berth. That clears the
Foredeck just about 90%. I don't use clips at the pulpit end. just loops
which I thread the lines thru after wrapping them around the pulpit like
a lasso.

I've had crew use them as Bow lines at the gas dock. They want me to rig
the stern the same way. They don't have to dig out docking lines and
storing them. They say I could use them for dingy slings.

Old Buddy I'll try to get pictures to you but I'm not to sure of my
photo transmit.

Thanks for the info.

THom..his boat's a 27'...if he feels that unsafe he can just pop up out =
of his forward hatch....

We were discussing a different type of "walking" used to make a multi
screwed vessel "walk" sideways, while DIW, longitudinally..... a very
useful maneuver in tights spaces and when docking.

Skilled hands make light work under power. Juggling thrust can walk a

I'd like to see that. Theory suggests that with small props & rudders, prop

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

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

Neal rarely gets either.
