We've been through several iterations of freezers on our trawler,
starting with a water cooled holding plate system, progressing to a
pair of Engel dual voltage air cooled units, and most recently an
Igloo home style 110 volt air cooled unit that we got from Home Depot.
The Igloo home style freezer easily maintains zero degrees with fairly
reasonable current draw from the inverter. It has a large capacity
of about 7 cubic feet and only cost about $300 brand new, actually
free since I got it with Amex reward points. The big problem on a
sailboat would be placement since it is counter top high, 2 feet deep
and about 3 feet long. We installed ours on the flybridge with a
custom canvas cover that blends in fairly well with the rest of the
decor.

Have you ever considered the inefficiencies involved with
inverting 12VCD to 120VAC? You tend to throw away 5-10%
depending upon various variables.

If I had your money and huge motor vessel I would install
a propane freezer as they tend to be far more efficient

-and reliable-

than their electrical brethren which electricity is usually
derived from burning the more expensive gasoline or diesel
fuel in generators.
