Thank you Arild. I know I can always take your comments literally to
the bank, and I will place Mermaid at the top of the list.

When looking at available air conditioning systems, keep in mind that
not all of them are created equal. One of the biggest names "Marine Air"
doesn't bother with soft start and they do not have the most efficient
compressors that modern technology can ofer.
A smaller company called Mermaid in Fort Meyers FL did a lot of
research to find the most efficient compressor with soft stat.
The difference in power comsumption, not to mention size of genset
needed to start the air conditioning is considerable. Mermaid now
sequences the start of the cooling water circulation pump and the main
compressor to reduce even further the start surge. Large diameter hose
and pipe for the cooling water also helps reduce the amountof current
drawn. This is something worth considering when trying to air condition
a boat with limited amounts of AC power available.
Quite often the large volume "name brand" products are relying on their
market presence to sell their product instead of actual technical
merit. They don't really care about refinements. They are driven
strictly by sales volume and the non discriminating buyer who accepts
"national name brands" simpoly because they are there, ends up paying
the price down the road in terms of operating costs and also in terms of
greater cost to delive the energy for such power hungry appliances.

Arild
