We have a 34 Greenland
FP power cat. The forward head
discharge thru hull
is located about 3 inches above the water
line. I noticed that the thru hull
is located in the same place on the Highland FP model.
FP has plumbed the boat
so that the head
pumps to the holding tank
. The holding tank
can be pumped out from the deck
fitting or drained by gravity via the thru hull
This arrangement is fine if you are 3 miles or more offshore
to discharge. However not fine in a marina! So I am re-plumbing my boat
with an onboard treatment system (Purasan) and larger holding tank (going from a 14 gal to a 25 gal). I plan to use the holding tank in no discharge zones and use the Purasan everywhere else.
My question is- should I relocate the thru hull
fitting to below the water
line for the Purasan discharge?
