Got a very unusual (for this time of year) rainstorm this week that brought more than three inches of rain in one day.  That brought clouds, which brought some nice sunrises and sunsets.  And despite coming down with a sore throat and cold, I got the hydraulic steering working again and started the installation of the new Simrad autopilot.  Ahh, the glamour of yachting!


Around La Cruz de Huanacaxtle


Can't let a little rain stop you from setting up your
mobile restaurant in the middle of a street corner.

Some folks like living, or at least parking, on the edge.

Looking southeast, it's actually a sunset!

Sunset at low tide

Damned grackles ain't got no couth!

Could be worse.  Look closely and you will see 
there are HUNDREDS of white-collared
seed-eaters on these wires.

Boat Work


Starting in on the new autopilot installation.
Always unnerving to cut big holes in the boat.
Measure three times; cut once?

Gulp!  Here goes.....

Nice, clean cut-out for the new Simrad autopilot
display and control.

Perfect fit

Protective cover on

Rebuilt base painted and ready for remounting the
hydraulic steering cylinder.

In order to make absolutely sure I didn't go through the
bottom of the hull, I used screws of different lengths
and carefully marked the drill bits to accommodate 
the amount of clearance.

Base remounted

Notice the rudder stop crossmember has been removed
to make installation easier.

Hydraulic cylinder remounted.

Hoses connected, rudder stop crossmember re-installed.

New Simrad autopilot motor/pump mounted 
and hoses connected.

Now the messy part:  filling the system with 
hydraulic fluid and then bleeding the air
out of it.  This is the set-up I devised 
last time I had to bleed the system.  It 
worked well, with minimum mess.

Some oil spillage is inevitable when bleeding
the system, so I prepared for it with oil-
absorbent pads.  After MANY repeated
turns of the wheel and some help from Tod,
we got it done.  It was good to at least have
manual steering back.

Thanksgiving in La Cruz de Huanacaxtle

A very busy and mixed week.  I explored more of La Cruz, partly in an effort to source everything from pumpkin pie to large stainless steel lag bolts.  In the midst of all that I went to the first public market of the season and went to a couple of tai chi classes.  I joined some friends in celebrating Thanksgiving on Delta Swizzler, a big power yacht out in the anchorage.  It was a very pleasant evening and we all had a good time.  I also continued to wrestle with the autopilot problems.  I have decided to replace the WH with a new Simrad or Raymarine so I can get parts and service more easily in Mexico.  I'm definitely making progress, albeit slowly.  As you'll see in the photos and videos, life here does have its compensations....

Thanksgiving


This is the pie shop in nearby Bucerias where I bought
a great pumpkin pie for Thanksgiving.  You can see
why I had trouble spotting it even though I had an
address and basic directions.  It definitely doesn't look
like a bakery!

First order of business:  an icy cold martini!

Next:  turkey time!  Mark does the honors.
(Yes, that is the galley on the boat!)

Around La Cruz


You never know what you might come across just
wandering around.

I happened upon a lovely spot that was well off the
beaten path for cruisers:  Playa La Manzanilla.

At the end of a dirt road.  No gringos.

I decided to try one of the beachfront restaurants,
La Serandia.

The name comes from the wood-fired 
barbecue style of cooking.  It was
every bit as good as it looked.

November 20th was Mexican Revolution Day, and the
local school children dressed up in costumes and
paraded through the town.

Not all of them seemed happy about it.



I finally found a machine shop to do some work needed
to deal with the autopilot problem.


Luckily it was next to a fastener shop where I was 
able to get the specialized screws I needed.  It
was the third place I had tried.

At the first weekly market of the season in La Cruz

The La Cruz market has always been one of the best,
and this year it has almost doubled in size.

The food section is always popular.

A wide variety of food and drink is available.

Flowers, Sunrises and Sunsets













Boat Work


While testing the old autopilot after installing the new
motor controller, several new problems arose, including
not stopping once the rudder hit the stops.  That resulted
in blowing out the end cap of the hydraulic cylinder,
dumping a bunch of hydraulic fluid into the bottom of
the lazarette.

The good news:  the end cap was held in place by a "C"
clip and was easily re-secured.  The O-ring appeared fine.

Decapitating a screw was the first step needed to
remove the hydraulic cylinder.

I needed to turn down some wine corks to plug the
hydraulic lines because I couldn't find any suitable 
plugs anywhere after looking for three days.
I used a washer to mark the center.

Did some rough preliminary trimming with a knife.

Then turned the screw into the center of the
cork, chucked it in the drill and turned
the end of the corks into a cone.

While not ideal, it did the job well enough so I could
pull the cylinder.

Next problem:  the base mounting screws were
completely rusted into the base plate.
I had to rip them out of the wood and fiberglass
mounting structure to get the cylinder out.

What's left of the mounting base after the plate
was ripped off.

Here you can see the separate small block (after it was
cleaned up) that broke off.

Old fiberglass matte and oily wood ground away

Getting ready to glue the block back in place with
thickened epoxy.

Block glued back in, epoxy filets added, two layers
of light roving and one of very heavy roving
with epoxy resin.

Rough spots ground fair and a final coat of epoxy resin

Old screws removed by machine shop and new 
stainless screws for remounting the base

Getting a perfectly mated surface by pressing base plate
into thickened epoxy, with a sheet of wax paper between.

Metal base plate removed, ready for paint.
