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?
