Recently found that the vent on my wast tank was plugged. It seems that the tank has overflowed in it's life & acidity of the fluid has caused the BRASS vent to just close up. I got the vent unplugged with a straightened out coat hanger. Disconnected vent hose inside and was able to punch through the vent. Anyway, I noticed all the vents,(water & fuel) are brass & crome and seemed to be insulated from the hull.
I'm planning to at least replace the waste vent.
Has anyone addresed this issue?

One of the first things I did with my 32' was to look at the fuel vents, which were chrome over brass. I mean "were". They came apart in my hands. I replaced them with the flush style of vent in stainless, that I think is very nice looking. They require a bigger hole.

Thanks Doug, Knew someone would have an answer.
The stainless vents look good.

Roger:
I traced my slow fush problem to the same plugged vent for the holding tank. Marinette used a fuel tank vent. It has a flame arrestor screen to prevent a fuel explosion. The 5/8" vent hose ran horizontal from the tank to the vent. When the tank was near full the contents must have sloshed into the hose and plugged at the screen. I replaced the vent with a Marelon vent and replaced the hose with a longer one with a tall loop that I tucked up behind the panel. This prevents a recurrance.
Tip: To test if your vent is plugged, try opening the deck pump-out fitting. If the head flushes noticeably better, your vent is plugged.
This discovery saved me a lot of money. I was about to buy an entire vacuflush system.

Did the same thing on mine. When pumping out the extra tank I added, you can hear the air whoosh in. Good thing the vent isn't blocked or the plastic square tank could get collapsed. Something to think about....

While your talking shit...
I'm debating constructing my own holding tank. Read about Epoxy/Fiberglass and Epoxy/Polyester construction. Has anyone heard if one or the other might hold up better? Heard about some that get saturated with the stink...I DO NOT want to do this job twice.
I found Ronco Plactics after searching the archives and they seem to have the most pre-fabbed sizes. Still nothing that would give me much more that 10-12 gallons of holding power. I know that the fore peak will hold almost double that so I have a difficult decision.
I'm afraid to ask but is Ronco the same company that makes the Vegi-Matic?

I added a 30 gallon holding tank on my 29. Poly tank that fits on a shelf between the rudder posts. works great.
No stink etc.

So, that's where the remark ("Won't plane off for sh*t!") came from.

Jeff, That tank back there wouldn't be much more than a guy of your stature standing back on the poop deck while under way @ roughly 8lb per gal x 30 gal  the trim tabs should handle it   Norm, Big  s Live On

With my inflateable and motor on davits I would not want any more weight back there even though it would be a great fit and easy insulation.

I resemble that remark! (Note that he said "poop deck".)

ComputerJoe,
I built a holding tank once for a friend, out of WEST epoxy and marine plywood, covered inside and out with 8 oz fiberglass. It worked.
Don't use polyester resin, it absorbs water. Don't use exterior ply, it has voids in it.
Briefly:
=> Cut out wood pieces to proper shape, be sure to have reach-thru access in top piece.
=> Rout a radius equal to plywood thickness on underside of reach-thru hole
=> Saturate all and put glass over interior of pieces, being sure to follow radius of reachthru to cover the edge.
=> Glue the whole thing together using epoxy and filler, do a couple of pieces at a time and have enough clamps! I own a couple of dozen.
=> Reach in and put a fillet of epoxy and filler in every interior join. Cover each with strips of glass saturated with epoxy. Wet out the strips on a table and then put them in place, wear gloves!
=> Rout the radius on each outside edge, rounding corners as well.
=> Cover each outside surface with fiberglass, thoroughly wet out, and overlap at edges. Do one side at a time, and let harden. A dragon's tongue will easily clean up the edges of the lay if your timing is good.
=> Drill for the reach-thru cover mounting holes and use brass threaded inserts, set in epoxy.
=> Make the reach-thru cover out of starboard and mount the fittings in it. Make a gasket out of silicone sheet. Use self-sealing stembolts to attach reach-thru cover to top of tank.
This is all documented in Meade Gougeon's book. I know you have long winters up there, but I thought if I wrote it out it would increase your enthusiasm for finding a ready-made tank. Don't turn up your nose at the flexible ones.....
