Hi gang:
With all the combined knowledge on this list, someone undoubtedly knows or
can point me to a source of information of how to design a sea chest.
Sometimes known as a water box, this allows one or two thru hulls to feed
multiple users of sea water, such as genset, air conditioners, washdown
pumps, watermakers, etc. My intention is to minimize the number of thru
hulls on my boat.
My current thinking is a 1-3 gallon box, as low as possible in the boat, two
1" thru hull feeds, three A/C units, one watermaker, one 12kw genset, one
27hp wing engine, (main engine is not involved) and one washdown pump. I
know I have to add up all the gph of all of these and see if they can be fed
from the available thru hulls, and I haven't done that yet.
Also, just as a silly idea, has anyone tried connecting the cooling water
coils of multiple A/C units in series? that is, the output of one goes to
the input of the next for (in my case) a total of three. It is rare that all
three would be operating at once, but they could be. The temperature rise of
the cooling water is only about 5 degrees through each unit. The advantage
of this would be one pump, one water source, and 1/3 the water volume used
if all 3 are operating.
Any ideas?
Russ
