Date: 21 July 2016. Moby-Cool a/c
This is a long article. You might wish to pour
yourself a beverage before sitting back to read. Thanks for your
patience while I tweaked it. More coming, and soon. I got behind and
even at five knots the times flows quickly. J.
A few days
ago I told you about my
Moby-Cool a/c cover Tweak.
This article will show you how it all came together. Here in Florida
between the heat and the humidity it can be miserable. I am at a
dock right now with access to a power cord. It is cool (read:
comfortable) inside my Seaweed because of the air-conditioner. Thank
goodness I have an interesting view.
Aboard Seaweed I am always looking for storage solutions. With the
Moby-Cool I can use my a/c anytime. That is a huge benefit. Now it
looks nice too.
thing I had jury-rigged to hold the a/c in place was dreadful. The
air-conditioner in the doorway meant one exit was always blocked. It
was unsafe and ugly too.
was not what I want for my home. Edwin and
Moby-Cool made it all nice again for me.
I have had
my head handed me on a platter for not showing you the finished
product in the last article.
Here is my girl just a couple weeks ago. And yes the air-conditioner
is on the topside. Invisible, eh?
The Moby-Cool is just aft of the pilothouse solar panels on the
overhead of the galley.
It is between the solar panels forward of the wind generator. (A
girl has to have power.)
My cyber friend Noel said "I could use this on top of my
airstream when I want to run it on the
small generator" and he is correct. This is an elegant
solution for those of us who cannot afford to spend $500-plus for a
roof-top RV unit.
I like it.
This is Edwin in front of the mangrove trees.
Screwing together the side pieces was easy because the holes all
matched. Please note the silver insulating foam on the inside. That
should keep my cool air inside Seaweed. It looks great.
Working under the trees helped
Barely with the heat of summertime. I am grateful for friends who can
help. Edwin has been a friend for many years. He knew how heavily
the air-conditioner situation weighed on my spirit.
I absolutely hated having my
air conditioner positioned in the doorway. With the a/c up top

on my happiness quotient.
Truth to tell, I was a bit
afraid of this project. Drilling holes in the overhead gives ripe
opportunity for leaks. And too, I do not have a lot of hand strength.
Edwin was a big part of the successful completion of the cover
Edwin double checked all the measurements.
Next he added the foam insulation tape to the top of the a/c unit.
The tape came with the Moby-Cool cover kit.
I had in my stash of stuff two pieces of 1" square hardwood. That
wood was used along the inside rim of the cover. The wood fit on the
lengthwise edges along the bottom of the cover. I wanted a backing
plate of sorts (not just the fiberglass cover) and the mahogany
served that purpose. Holes were predrilled so when installation time
came it was an easy matter to line things up.
Four holes along each side at the bottom edge firmly hold the cover

permanent installation. I wanted this item to stay put even in a
hurricane. I have not tested that as of yet. The Moby-Cool cover has

Side Note: I
tend to prefer to thru-bolt items where others might use screws. On
Seaweed often there is nothing on the other side of the gelcoat/fiberglass to fasten
securely to. That is why I go all the way through the bulkhead using nuts and
washers on the other side.
I always use stainless hardware. After drilling
the holes I stuff them with a sealant.

turn on the a/c for an hour or so to cool off the boat.

close enough. I've seen 475 at a peak. Currently it's reading

reason is Christmas. I anticipate hanging lights from the overhead
using that outlet. Christmas is my favorite holiday. Bing Crosby sings to
me. Frank-be-still-my-heart Sinatra, Rosemary Clooney and Dino
brighten my days. Life is good. It is most excellent to be on a boat
at Christmas time.
Edwin did a Wonderful job in making the a/c
pretty for me. I am beyond thrilled. Thank you Edwin.

As you can see it neatly fits between the solar panels. The
Moby-Cool cover allows me to have an inexpensive small
air-conditioner topside without the boat looking shabby.
From the aft quarter, the air-conditioner:
Seaweed is not a fancy yacht. I am thrilled with my home. The
addition of this air-conditioner has made my life quite comfortable.
I love that the Moby-Cool cover allowed me to mount the a/c unit out
of the way yet easily accessible.

Southwinds Magazine. I phoned 407-435-9733 and left a message.
The next day the owner/designer called. His name is Scott.
Thanks again for your patience. Congratulations for making it to the

key component to my comfort. I am happy leading this life of

give a call on Channel 16. I am always listening.
August 2016. A new friend, Tex, asked how
specifically I attach the air conditioner to Seaweed. I missed
that part in the article. Oops! Thanks for catching that Tex.
A/C TO COVER →
TEAK BACKING PLATE
I took a piece of teak one
inch by 1/2" thick the width of the cover. That hardwood was
used as a BACKING PLATE. Four
SCREWS go through Moby-Cool cover,
then teak and finally into the air-conditioner.
I was also concerned that
the unit might slide back in rough seas. Thus I finally found a
use of that 1" aluminum angle iron (is it called iron when it's
aluminum?!?) The ALUMINUM BRACE is
thru-bolted into my cabin. That a/c is going no where.
- 1" ALUMINUM BRACE
When the air conditioner
does finally quit on me, I'll simply remove those four screws
and lift up the unit while pulling it aft. Then I will buy another
$100 air conditioner and call it Good Enough.
I'd love to hear what your cooling solutions are for
And, are how do you power your solution?
