Subject: TWL: TWD - Sea Chest / H20 Manifold
From: Martin I Veiner (veiner@XXX.XXX)

I'm interested in finding out if there are any definitive articles that
would let me design a chest/manifold that would have several taps and
feed two Ford Lehman 120 diesels, an Onan generator, and several other
low demand or low capacity devices. What size should it be?
It seems like a properly designed system would save on thru-hulls, save
on valving, save on hose material, and save on raw water filters. etc.
But I assume you have to find the needs for all of the equipment running
at the same time, in GPH, as well as having a built in safety factor of
perhaps twice that GPH, so that you avoid air locks or some other type of
system failure. The consequences of system failure for the motors is
disaster, as you could wipe out not one, but three motors due to a
blockage, failure, etc. Don't you want redundancy when the cost of
failure is so high?
Hope there are some engineers reading this post that can provide
objective technical advice on size, shape, take-offs, etc. other than the
anecdotal reports that these systems were seen on other boats and seemed
to work on those boats.
