[C38] ice box Alden Andre

Mon Jul 14 12:07:05 EDT 2008

I have an alder barber set up in the ice box but don't use it much. I
have found if I put 3 blocks of ice in the bottom then fill with ice up
to the grate holders that the ice will keep for two weeks. Of course I
live in the pacific North West and not Florida so the temps are a little
cooler. The ice will last two weeks without the use of the fridge. Since
I have cut out the lazerete I don't see much insulation around the ice
box but now I have access I will remedy that. Hope this helps for your
trip planning.

Unfortunately, on our 1980 model there is only about 1 inch of
insulation
around the ice box.  When I added refrigeration ( a large freezer box
fits
perfectly on the outboard shelf) I put low expansion foam around the
box.
Shortly thereafter, I noticed that the floor of the ice box was warm
after
running the engine which lead me to believe there is no insulation there
so
I blew more foam under it.  There isn't much room on the engine side for
insulation so I glued a metalized bubble wrap to it.  I would like to
replace it with some of the Glacier Bay evacuated foam later.

I would say that running the engine is more a factor on the
refrigeration or
ice needed than how many times you open it.

Question from my wife for all those that use the ice box.  Our upcoming
trip
this week will be our first long sail (10 days) with the boat and she is
in
the meal prep stage.   I was looking at the proximity of the ice box
stbd
side to the engine compartment and wondering how much if any insulation
there was.  Then the real question how long do our ice boxes keep things
frozen, assuming your only in them once or twice a day.   Thanks.

Steve,
    We have found that the secret with ice boxes is to have some block 
ice and some dry ice. You carefully wrap the dry ice and put it on top 
of the block ice. It will keep it an extra day or two. Be careful not to

touch the dry ice with bare hands because you can get a bad burn. You 
can get it at most ice houses. In an ice box, things do not stay frozen 
very long, even with the dry ice.  Joe Launie, Macavity, Commodore

Our 38 is kept in Florida. We converted our ice box to a refrigerator
but we also insulated the box inside and out.

We first cut an access port on the forward bulkhead of the sail locker
so we could glue 1" metalized foam board to the back and engine sides of
the ice box.  We hand packed insulation on the outboard side of the ice
box and used a stick to pack insulation under the ice box.  We ran a
conduit under the ice box so we could continue to run and service wires
and plumbing if needed.  We glued 2" foam to the bottom of the teak top
lids and coated the foam with epoxy to make them more durable.

We were still not satisfied with the thermal efficiency of our
insulation so I then cut 2" foam panels to line the sides of the inside
of the box.  We figured we have a larger box than we will ever use so by
insulating the inside we greatly improved the insulation and made the
cooled area smaller reducing demand on the refrigerator.  The inside
panels are fit for a snug press fit and are removable leaving no trace
when removed.

We put a 2" foam panel on the bottom lift out tray so the bottom of the
ice box is no longer directly refrigerated and we now put extra
provisions like water and soft drinks there where they will partially
cool before we bring them up to the upper level for use.

Our refrigerator is now so insulated we can run the refrigerator on
battery alone for several days and everything stays cold without killing
the batteries.
