thanks everyone for the ideas. i had searched thru peggy's book and
could only come up with white vinegar. i also tried some stuff sold
by a nearby pet store as a cleaner used by vets/kennels to clean up
odors - it's an enzyme product like pure ayre. and i opened up all
hatches and put a fan where the tank had been and ran that for about 3
days. it's a lot better - but the odor must have gotten into the
glass where there's no gel coat. i'll try the other products next.
consensus seems to be to put in as much rigid pipe as i can fit. i
take that to be pvc - sch40. i'm offshore most of the time so my set
up is this - one hose from bowl to holding tank; one hose tank to
y-valve; one hose from valve to pump out on deck - the other to a
manual pump overboard. i think the worst hose was the one from the
pump overboard. i think i need to fill the tank with water after i
pump it out and pump it again to make sure that hose is clean.
while i'm at it - i'm going to implement an idea from the capt who did
the survey for me - he said to put a second vent on the other side of
the hull - there's always a pressure difference to cause air flow.
any comments are welcome. and thanks again.

i have removed the permeated (and smelly!) sanitation hoses along with
the holding tank and vent hose. i have a strong lingering odor where
the hoses were. i am in the process of replacing all hoses along with
the holding tank - but i would like everything to be odor free before
i install anything. i would appreciate any ideas.
thanks - bob t
