lharmon We changed our holding tank about three years ago. We gave up some storage but have never regretted it. My bet on your odors are old hoses. But you may have a clogged vent line. Especially if anyone ever tried to pump into a full tank.

We figured the location for the new tank and then bought the largest that we could fit. We had to tab in supports so we started with some closed cell pipe wrap and tabbed it to the hull to prevent any hardspots from forming. We then attached a frame to the tabbed in shelves and set the tank in the frame.

I had to cut a few pieces parts of the boat out of the way and splice them back in. But it was not too hard. I did the whole project on our mooring using cordless tools. Ripping out the old tank and dryfitting the new one and tabbing took about three hours the first day. Setting the tank and putting the boat back together took about two more hours.

It took more time to plan than to do. I wish we had replaced all our hoses then. They are on the list for this spring. Soak the ends of your new hoses in a pan of hot water and it will be much easier to install them. Double high grade hose clamps are imperative as well.

Hope everything comes out OK.

rennisaint Another tank to consider is a flexible holding tank, easy to remove for cleaning etc., and expandable in size.

sailingdog CP-

cardiacpaul "BTW, wrap a cotton towel that's been soaked in near-boiling water around the hoses on your head.... "

Hey dog, I tried that and damn near burnt my ears off. thanks for nuttin'.

sailingdog A larger tank won't help with odors generally. Better ventilation of the existing tank is probably easier and more effective. BTW, wrap a cotton towel that's been soaked in near-boiling water around the hoses on your head.... then after it cools to the touch...take the towel off and sniff it...if it smells like sh!t, then your hoses need replacing, since they're permeated and they're probably the cause of the smell.

chucklesR Check out some of the composting heads, AirHead comes to mind - simplest way to replace a holding tank is to not have a holding tank - or the smells associated with it.

larger holding tank

Just as we suspected. New hoses, a larger tank, and fiberglass a platform. These are on the "to do" list. I would love to have a 30 gal holding tank.
We want a windlass in the bow so that may help with weight distribution.
Thank you every one for your input. This is a great group!

Holding tank

Good point about the weight distribution. Fortunately, our fuel and water tanks were on the opposite side and balanced well.

PBzeer Two things to keep in mind are weight distribution and length of hose run.

Freesail99 The odors may be coming from old sanitation hose rather then the tank. If you have room to put a bigger tank, measure the area and go to

See how close you can come to the size tanks they offer.
