Re: Chebacco self steering

Chuck @ Duckworks has a really neat setup on his Caprice for tiller
control.

Basicaly, a rope goes across the stern, just above the tiller. On the
tiller, just in front of the ropt is an eyebolt. In front of the
eyebolt is a cleat. A short rope is attached loosly to the main rope.
There is enough slack in the main that it can be pulled through the
eyebolt about three inches, doubled over. The short rope pulles the
main rope through the eye and is cleated to adjust tension. You can
set this up so the tiller will stay where you put it, and you can
still move it buy just giving it a shove. Very cool.

He also had a neat setup for a auto release on the lashed down
leeboard, but he will have to give you the details on that one.

Greetings from the other end of the country.

Can you give some details on your comb -- does it work downwind? How
big/small are the teeth and how do you attach it so its not in the way when
not in use?

Cheers,

Jamie

Greetings from Halifax
My chebacco is fairly stable. It is easily set up to mind itself. I
sheet the mizzen to give some weather helm, then lock the tiller in a
tiller comb. It is quite sensitive to fore and aft trim, so you can't
move around a lot and expect it to stay on course. I wouldn't call it
self-steering, more that it doesn't need a constant hand on the helm. I
find it difficult to single hand without the comb.
It can point to 45 deg to the wind, but it hurts. 55 deg is more
comfortable.
We are happiest in light winds. Hull speed at about 10-12 kts wind. Now
I try to get a reef in before whitecaps start to show. In 15 kt wind, it
is overpowered with a full main. I used to keep everthing up and carry
on upwind with a 20 or 30 deg list, helm hard over.

Two comments about catboat sailing in general.

1) In deciding how far in to sheet the boom while beating, remember
that the pivot axis of the sail is at the bow, more like a jib than
the main sail of a sloop. A genoa is typically sheeted near the rail
near the widest point of beam. Therefore, the boom of a catboat may
cross the rail at about the widest part of the boat. With a Cape Cod
cat with wide beam, the boom would be in farther, generally with the
end of the boom just about over the corner of the transom. Don't take
these specific guidelines too seriously; the point I want to make is
that it is easy to overtrim and have the boat point high but go very
slowly.

2) With most catboats, if you let the boat lie broadside to the wind
with the sail just about all the way out, the boat will hold steady
making a little forward motion and a little leeway. If the bow heads
up a little, the windage of the mast and sail blow it off. If the bow
heads down a little, the sail fills and generates weather helm, and
the drives the bow up again. From this situation, if you pull the
sheet in, you can get more and more forward motion with less and less
leeway with the boat continuing to selfsteer. Howeever, you have to
be more or less on the edge of luffing. The mizzen should give you
bigger range of adjustment to make tricks of this sort work.

Hi

Note the following is based on less than a dozen outings, using home-sewn
sails. We've not had a summer season in her yet.

I haven't worked at it a lot, but Wayward Lass has steered herself on
occasion. One time that sticks in my mind was in light wind, when I didn't
have the mizzen up at all -- she kept a very constant course, a close reach
to close hauled, I don't have a wind vane so can't say how small an angle.
I've also used the mizzen to steer with while the rudder was left to its own
devices, which I think shows potential for self steering.

In regards to close-windedness in general, I believe we go better if I don't
try for too small an angle to the wind. I don't have either a speed
indicator or wind vane, but my impression is that when I'm as close to the
wind as I can get, she's not moving as fast as when I let her fall off just
a bit. However, I've been satisfied with windward performance so far.

Hope this helps a little.

One of the reasons I'm considering building the Chebacco light
cruiser is the ability to self-steer.

How well does the Chebacco self steer? I've been on some cat-yawls
that had a mizzen to small to steer the boat, and I've been on others
that would self steer, but only about 60 degrees off the wind.

Any of you Chebacco sailers care to give a report? Will the Chebacco
self-steer? How about in light winds? How close winded can you self-
steer the thing?
