Holding Tank Capacity 53MY

[Freeebird]

I'm assuming there will be some variations, but what is the factory holding tank capacity on a '75?

Yes, I'm asking for Robby because he doesn't have a laptop at the moment. Brokerage listing shows 2, 50 gallon tanks. That very well may be as these things can get changed, but I don't remember those boats having two tanks.

They did have two tanks. My 53 still has the two pump out fittings. That said things may have been changed. Mines were removed in the 90s when VF were installed and replaced by a single 100 gal under the forward cabin floor.

Interestingly I looked at the manual and no holding tanks are shown. They must have been optional in 1970 and added later on. I have a disconnected pump out fitting on Stbd all the way aft, one on stbd just past the PH door and one at the bow, currently used for the 100 gal tank mentioned ealier.

I wonder when hatteras installed tanks at the factory. I wonder what kind of head hatteras used in 1970. The single paragraph instructions for the “toilets” said to press the pedal while holding the switch on the cabinet to flush

My year 79 has two totaling 120 gallons.

I don't think there were laws dealing with direct overboard discharge in 1970. I know people "modify" these older boats, so I'm assuming maybe the broker knew what was in the boat. Then again, you know how some brokers are.


Seriously, I negotiated this deal and the broker seemed to be a straight shooter on every level. I do know the boat underwent a $300K refit a few years back, so maybe the tank(s)were replaced then.

My 1974 53MY had a 100 gallon tank fwd and a 50 tank in the stbd engine room outboard of the engine that you walk on. Both look to be factory built. My fwd tank was converted to fuel by a PO. And now I am removing the engine room tank for my stabilizer install. New 60 gallon tank going in the gen room outboard to Stbd., John

Like I told Robby, it just is what it is. I understand the concern from the standpoint of being a liveaboard, but that just means you pumpout more often, or install a bigger tank.

Or you add a lectrasan if legal in your area.

Pump out more often works if you have pump out at your dock. If you have to go somewhere or rely on a pump service on fixed day, it s a pita. Here in Coconut grove, the marina never replaced the main pump that was submerged in Irma 2 1/2 years ago. Instead they use a pump out boat twice a week. Well now once a week because of the virus.

I think the larger tank comment pretty much covered that.

1978 53MY, from the manual, 165 gal. total.

The center bow holding tank is 105 gal. And there is a starboard tank (under the dinette in the bilge) that holds 60 gal. After looking at the blueprints for the engine electrical system, the 60 gal tank is just in front of the generator muffler, under the dinette.

The master and bow heads use the 105 gal tank, and the guest head uses the 60 gal tank.

I am kind of amazed that the master head pumps all the way to the bow tank.

Electro scan is the current version. Know it well. Sell some too. I just refrain from servicing them after use.

Our boats only a year apart, I find it hard to believe that you have an additional 40 gallons of holding tanks. They were in the same location as mine so maybe my information is incorrect. Do you have it written on the specs?

 

[SKYCHENEY]

Mine are the same. 60 gallon stbd gen room and 105 fwd bilge area for a total of 165. From 1978 on that would be the standard. I'm not sure on the pre-1978 boats.

It is on the front specs page, 165 gal, and in the blueprints, 105 and 60.

 

[Pascal]

1970 was really a different era. Nothin mr in the blueprints, nothing in the manual about holding tanks. I guess it was dealer installed then

 

[Jammin']

From what I have read, holding tanks were standard after 1972 and some boats from 1972 had tanks already, but they weren't hooked up and didn't show on the prints.

 

[bigbill]

my 72 58 yf has 2 one in fwd bilge and 1 in stbd engine room, not sure of capacity

 

[chuckbullett@gmail.com]

Our 1978 53MY has a 55Gal tank forward and a 45 gallon amidship on starboard.

If you believe all the answers here, it sounds like Hatteras did not have much standards for holding tanks. I know they modified lots of things on these boats over the years and it appears that holding tanks were one of them.

 

[SKYCHENEY]

I think some of the answers are incorrect. I'll bet if you 53/58 owners actually figured the volume of your two tanks you will find that they are all 105 fwd and 60 stbd. I don't see Hatteras changing the molds for these tanks once they started making them.

To calibrate my Heart Tank tender, I actually metered water into my tanks through the pump-out fittings. I know mine are indeed as the owners manual states.
