from the Coast Guard for having a direct discharge head...even if the
aft head goes into a holding tank, and is the only one used when we
are not out.

Easily solved: put a y-valve in the line so you can flush it directly
overboard...tie-wrap the seacock or the y-valve handle closed when
you're inside the "3 mile limit," and you'll be in 100% compliance with
marine sanitation laws, so the CG won't have any reason to hassle you.
