Re: Holding Tank

I Think one of the most aggravating problums I have had with
GHOST "EL Condor Pasa" was where to put the head holding tank, I
sail on lake Huron and there is a zero discharge law strictly
enforced, I measured every space in the boat checked available tanks
for size and found nothing seemed to work, a little 3 or five gallon
tank didn't seem worth the trouble. So i bit the big one and
converted the dry locker under the V-Birth into a 28 Gallon built in
holding tank and it has worked very well and had no major trouble,I
epoxy coated the well sanded gel-coat and installed a one half inch
plastic(King Color Board) top with sending unit to monitor level of
I know i have given up storage space but everything in life is a
trade off and this one seemed worth the loss.
Has anyone else done anything like this? or what have you done for
holding tanks and what were the results?

Re: Holding Tank

I have a 13 gallon holding in the storage locker accross from the head. I am actually replacing the hose with a higher grade in an effort to imporove the odor it is emitting. I got this boat about two months ago with it pre installed. It appears that when it gets full the fiberglass around it expands due to the wieght offset. I will be building a shelf under it as well this weekend. I'd rather be sailing but this is important so wish me luck.

Has anyone ever installed a holding tank in their C26 MKII? Where did you put the tank? Where was the vent and pump-out?

Re: Holding Tank

I just recently install an 18 gallon holding tank under the cockpit just behind the step. I removed the toilet instruction lable, used a roto zip and cut a hole, than cut a hole in the bulkhead leading to the cavatity behind the table, pulled hose out under seat by the sink, and ran hose into the aft cabin and to the tank, installed vent on port side and pump out on deck in cockpit area.
