Need advise on replacing a blader type holding tank on 1980 Hunter 30. Is there room for a fiberglass tank? Thanks

Not without cutting something
I tried to fit a plastic holding tank in one of the three v-berth lockers in my 1980 H30. I could not find one that was both large enough and would fit through the openings without significant cutting &/or modification. I ended up using a 15 gal. bladder in the port locker. As long as you keep it clean there is little to no smell.

holding tank on H30
Ron with the H33 has the right idea. I found a 9 gal. tank through WM that fits into the port v-berth locker. I did not determine a need for larger capacity holding tank. The tank is attached with 2x4's the way Ron did his. I made aluminum bands fabricated from material available at home improvement stores. Three bends and a couple of holes for bolts and you have mounting bands. It is installed at the top of the locker on the inside against the bulkhead. The back of the tank is against the bulkhead. It does not sit square. You must improvise. Then, the plumbing is installed according to Ron's diagram. There's a few more turns, but the result is the same. I opted to use a combination of flex hose and PVC. The ball valves and thru hulls of my H30 are below the tank in the same locker and in easy reach. As a suggestion, add a clean out fitting just before the inlet to the tank to facilitate adding treatment chemicals and the occasional fresh water rinse out. It works for me.

Different solution....

Why not post your suggestion here, jerzey?
We're all curious to know what it is. Mike in Greenville NC--6 gallons isn't big enough for Mike in Sandusky....you're in coastal waters with immediate access to open sea beyond 3 miles...he's on the Great Lakes, which are "no discharge" waters. So while all you need is enough capacity to hold you overnight while in port, he needs enough capacity to last all weekend...or longer...at least 15-18 gallons...maybe more depending on the size of his family.

Peggy doesn't know
that we have an adage here in North Carolina that goes, "those that think they know it all only annoy those of us that do. In the first place, I said 9 gallons and not six. This is adequate, but admitedly not ideal. Idealy, I would prefer more capacity in my holding, fresh water and fuel tanks. However, if I really wanted more I'd buy a larger boat. Otherwise, I have jerry cans for fuel and water. We plan our cruises to use the pump out facilities at marinas along the way unless we do go offshore. In addition, I suggested a fitting to allow the introduction of treatment chemicals. I had in mind the type that lessens the environmental impact of dumping a holding tank. Second, check the chart and you will see that the Atlantic Ocean is outside the barrier islands (OBX). My boat is berthed fifty miles from the nearest outlet which is at Ocracoke Island. That's quite a ways to go just for a dump. Thankfully, the marina where my Hunter 30 is berthed provides free pumpout. This is added incentive not to dump your tank inland. Our inland waters and salt marshes are the nurseries for the ocean. Recreational and commercial vessel operators watch these waters and strive to protect them. Further, The waters of eastern North Carolina are inland coastal. Although they are not designated as "No Discharge Zones", the estuaries and sounds are protected under North Carolina General Statute 79. So, don't plan to dump your holding tank here. There is a $500 or higher fine. Fortunately, many marinas here are upgrading and adding dump stations thanks to federal money specified for that purpose. Finally, Mike of Sanduskys question is related to replacing a bladder with a fiberglass tank. Since I own a H30 Cherubini also, I offered a suggestion based upon the refit I made. The adaptation was made according to my preferences and the space available. Simply, as most sailors know, you do the best you can with what space you have.

6 gal...9 gal...still pretty small
And since many boat owners don't necessary live and keep their boats in the same place--even the same states, that you show Greenville as your home "port" leaves a LOT of NC, and even SC, coastal waters open as possible cruising waters for you...many of which do offer immediate access to open sea. Actually, you'd be an ideal candidate to replace your tank with a Lectra/San. The amperage DRAW looks a bit scary...but actual daily CONSUMPTION for two people averages less than 20 AH...well within the resources of any 30' boat with better than the barest minimum of battery power. And it doesn't need much, if any, more space than your tank. There are no tank products that "treat" waste...only those that eliminate, reduce or mask odor. Nor are there any that lessen the impact of a dumped tank on the surrounding waters...any that attempt to reduce odor by killing bacteria only put HIGHLY toxic chemicals into the water...neither those that do or don't kill bacteria do anything to reduce BOD...so there's nothing to be gained by adding any kind of separate fitting to add anything that can't be flushed down the toilet just as easily. Which is one of the things that make a Lectra/San an excellent alternative to holding tanks...it doesn't use chemicals to kill bacteria, but instead creates a type of "chlorine" by charging the ions in salt water with electrical current...killing bacteria during the treatment cycle, but reverting to salt water again when the stimulus (electrical current) is removed. And, in the process, reduces BOD by at least 35%. And btw...the coastal water of NC are not only protected by North Carolina General Statute 79, but also by the same federal laws that make it illegal to dump a tank in ALL U.S. water--coastal or inland. If the barrier islands are more than 3 miles offshore, you could legally dump a tank in the waters that are more than 3 miles from the mainland AND 3 miles from the nearest island...but otherwise, you'd have be 3 miles out to sea from the east side of the islands.

I'd like to post it...
But how...? It is MSWord 5-page document with multiple pictures imbedded. Any place at "hunterowners" that would allow such document to be posted? Jerzy s/y Free Spirit
