Tim,

Which thru hull did you use, the sink drain or the seawater sink intake?

BTW, we used to based out of Branford, Brewers B dock, out on the end.  Great 
cruising kick off location.  Loved the 6 foot tide and tidal currents heading 
eastward out of the Sound.  Nice little town too.

I have the SP unit on Mojito.  There is no pump and therefore nothing to inhale 
jellyfish.  When I received the unit, my main concern was the brass 
construction (not bronze).  It has it's own zinc, which I have not had to 
replace over two seasons, so no issues yet.  It works very well in LIS, and 
yes, even on the hard.

 What's the heat transfer coefficient for a jellyfish, anyway?

  I looked hard at the heat rejection issue because the water temperature on 
the bayou where I keep Touche' can exceed 85 F at times.  I'm thinking the 
refrigerant is 220-250 F in the heat transfer coil in the thruhull.  That's 
quite a bit of temperature differential for heat rejection.

  I like the idea of no cooling fan or cooling water pump for both energy and 
reliability.

    Pete,

    I'll look the next time I'm in Hampton.  Originally I had two Rolls wet 
cell batteries, 330 AH total capacity.  They barely fit into the well under the 
aft cabin bunk.  The were strapped in, but I couldn't get the battery box tops 
on and secured.  Topping off the center cells was a bear.  After the lightning 
strike, I replaced them with AGMs which were lighter and shorter which 
facilitated getting the bunk baseboard to fit level in its inset.

    BTW, one of my concerns with the reefer was the water cooling issue.  I see 
those jellyfish in the water and I wondered if the SP action would suck them 
in.  Glad to see my concerns were well founded.

    allen, Hi,
    I have the "Cold Machine" [Adler/Barbour] in my 30.  It's air cooled, and 
I've had no problems with it in the 10+ years I've owned Siren Song.  
    It was installed by PO.  
    It is located under the port settee, directly in front of the galley sink.  
It's vented on the right just above sole.  
    Because it's air-cooled, it probably adds to the cabin temps, but I don't 
think it's material.  
    I'll freeze a gallon jug of H20, put it in the box, and turn on the frig.  
This gets everything cold quickly without a lot of melting ice.  
     
    FWIW,  a cruising friend of mine has a water-cooled unit [Grunnert, I 
think].  While the unit does a really good job, we had lots of problems this 
past season with blockages mainly due to jellyfish ["the cockroach of the 
Chesapeake!].
     
    So, I'd go with air cooled unit.  
    As far as ampacity, I have 2 house batteries, and 1 start batt., but it's 
probably 50% of your capacity.   I usually leave it "off" unless I'm plugged 
in, or motoring.
    I'm curious what brand of battery you have, and did you have to modify the 
aft cabin space??  I'd like to increase my amps.
