Replace the tank. You are getting into the project to replace the
hoses, why not do the tank at the same time. Look at the type of tank
used for the group purchase last year. I think they are performing well.

Mike's right about not wanting to use the water tank...it's guaranteed
to permeate odor because it's made out of the wrong materials. My
understanding is it needs to be made from polyethylene.
Now I want to state my problem for your inputs:
I can't get rid the smell and I got a polyethylene tank. The
consensus of everyone who's sailed with us this summer is that it's
disgusting. I know now that I've got the wrong hose and will replace it
this winter when the smells manageable. But I also believe that there is
a second source emanating the dreadful aroma. For whatever reason the
tank has 3 or 4 plugged holes (nominally 1" white nylon pipe fittings
with teflon tape, or maybe pvc or a white something--these are in one of
the vertical sides and are often have liquid bearing against them). The
tank also has a screwed-in man hole with the white o-ring and a clear
acrylic cover or something like that. In looking at the new tanks that
I've seen all fittings are welded in these days. But I also noticed at
the boat show that they sell level indicators for holding tanks that
screw into the standard man hole. And the Kragor catalogs shows tanks
with man holes as standard. I'd like to order a new tank with no man
holes and only welded in fittings and use the best hose...is this right
track? Or do I just replace the hose and hope that enough?

I would never use a permanent tank for waste. What if the tank became
permeated with odor? How would you change it? As a rule I never have
waste in the tank while the boat is not in use. When the boat is put
away after the weekend, I pump the tank, fill it with a fresh clean
water rinse, and then pump the rinse water. Mine has no odor after 6
years of use. I also make sure to flush the lines with fresh water to
prevent waste from permeating the hoses.
A couple of lesson here....
Buy the best hoses you can. The double-wall rubber sanitation hose
(about $10 per foot) is the best. Use PVC elbows where you have to, but
keep connections to an absolute minimum. Do not use ALL PVC because of
failure due to freezing (I replace the fresh water lines to my pier
every year because they crack longitudinally even though they were
drained). Avoid having an "low spots" in the hose installation where
waste can lay.
The odor from the tank does NOT come from the waste! It comes from
anaerobic bacteria in the system. A well ventilated tank will create an
aerobic environment that will prevent the bacteria from growing
(another good reason to keep the tank emptied). Use two vents, one to
each side of the boat to promote free-flow of air through the tank.
Done and maintained properly a holding tank will provide years of
odor-free service.

RE message below sent a few minutes ago, please substitute effluent
for
affluent. Or, just change to read as follows:
Lastly, imagine a 35 gallon holding tank! I could chauffer the
affluent and
their effluent around
the Chesapeake Bay all season, stopping only for the occasional
Perrier
delivery (they do deliver, don't they?).
Sorry about the mix up. I would like to blame it on spell check
