Hey silly, Yanmars turn clockwise looking at them from the stern.

Unless you have a weird, v-drive tranny or something your props
turn clockwise.

Both turn the same way, Counterclockwise, when viewed from the stern. I think. I
actually had a prop in my hand this afternoon to bring home, and decided that was
silly!

But I do know for sure they both go the same way!

G May be wrong answer .... when looking from astern, both props turn
clockwise, when engines ahead? or does stbd turn one way and port, the
other? (may be part of the reason for no walk).

Yes.

There're not counter-rotating.

As to what happens when I try to "walk" - I can't quite remember exactly - she
just
jiggles forward or back but never really gets and loser to the dock! Of course, I
wish we
had this discussion yesterday, I could have tried it out this morning! But as
they
say
here in Boston, "Wait till next season!"

Dang it! That's twice I forgot to ask .....inboard or outboard turning
props?

Walk set-up is correct (props control bow, rudders control stern). Don't
think your keel (from what I saw in the picture) is the problem.
Seemingly (but not) unimportant question .... which end lags behind ....
bow or stern? (in your example, hard right rudder, engines clutched,
only,[no throttle] for left twist) BTW, I'm hoping you say bow, lags
behind G.

Oy! You had to ask! It isn't easy to remember with the controls in
front of me, but I
guess:

To walk to Port, Rudders to Starboard, Port Engine in Reverse,
Starboard Engine Forward.

The works with many twin screw boats, but I think mine has a keel that
too long - I wonder
if its too efficient at low speed? Also, although the rudders are
large, they are hung on
skegs and set back a bit from the screws, which are folding. I think
all these things add
up to minimal "walking."

G It varies a lot with all multi screw (except tractor tugs). From the
look at the picture, I would think she'd "walk" fairly well ( I'm
talking about sideways motion, not prop walk).
Just out of curiosity, when you set up to "walk" to stbd, how do you set
your engines and rudders? .... and which part has the problem keeping
up, bow or stern?

And the answer is:

It varies a lot with the cat. Some have long keels, others have
daggerboards. Some


have


steerable drives, some have a single outboard, some have a widely
spaced diesels.


Some


have little windage, others a lot.

My boat has long keels, low windage on the bow (more aft), and
widely space diesels.


She


can pivot in place very nicely but has little prop walk. People
have told me they


could


make it go sideways, but when I've challenged them to try, they've
always failed. I


often


have to dock on a face, which is actually often tough - I usually
rely on getting


close


enough to snag a cleat, then springing in the rest of the way. If I
have a few hands
around to help I can usually get the boat anywhere I want. The
hands don't have to do
much of anything, but I find it difficult to singlehand because the
visibility around


the


edges is limited.

This morning I had a special challenge - I had to back into a
TravelLift the is about


6


inches wider than my beam. The wind started light, but picked up
to about 15 knots


cross


as I was coming in. The real problem was that one prop had trouble
staying open in
foreword - I had to do most of the work with just one engine. This
made it difficult


to


stay lined up. I felt that I totally turkeyed it, but I was
complimented by the Lift-
Meister and dockhand, and no damage was done. I found that the
gearing that forces to


two


blades to open together had totally sheared off.
