Default SSB counterpoise for a catamaran

Peter,
Reading that 100 sq ft were recommended gave me pause; apparently not that
much is always necessary, but my bilge is broken up by numerous bulkheads or
ribs, which makes this difficult.
Thanks.

I did it recently using roofing copper. I bought a 2 ft wide piece about

6
ft long and stuck it down in what was normally an inaccessible part of the
bilge using 5200 for adhesive. I used the 2" wide strip also to connect
from the receiver to the tuner and join to the copper sheet along the way.

I'm about to install the SSB ground system in my catamaran. Since I

don't
have a lead keel, and my water tank is well above the w/l, seems I might

be
needing to lay down a lot of copper strips in the bilge.
The operators manual suggested that a 3" strip separated 3" from an

adjacent
3" strip would be equivalent to a 9" strip. Is this the maximum

separation
to achieve this phenomonem? If the strips could be 2 feet apart, and

still
be effective as a 2+ foot wide strip, that would save a lot of time and
materials. Probably too good to be true though. But if it did wow, maybe

I
could lay strips in both hulls, connected together at each end, and have

a
monster ground plane.
Since this probably wouldn't work, what is the most efficient way to

make
the ground system in a catamaran?
