Hi Peggie,

Its an Irwin Citation 38 aft cockpit. The routing
from the head back to the holding tank is not too
bad. The routing from the thru-hull to the
holding tank is not too bad. The routing from the
head to the thru-hull is damn near impossible--a
reason why I'm seriously considering routing
everything through the holding tank.

Primary use of boat is as a liveaboard for two
people while cruising. OTOH there will certainly
be visitors aboard at times, and they will be
landlubbers.

Ummm...folks...if he has a 40' MY and regularly has a gaggle of
landlubbers aboard, a Lavac would be a ridiculous choice...and if the
route from the toilet to the tank and/or thru-hull is something only a
snake could love, hard pipe isn't a good option either.

He hasn't provided enough information yet to allow any of us to make any
recommendations that are right for HIS boat.
