Hey guys,

My CNG regulator assembly which attaches to the tank in the aft stateroom seems to be broken. When I connect a full tank, tighten the nut, and open the tank valve, gas leaks wildly around the nut. Here is a picture of my assembly: https://dl.dropboxusercontent.com/u/1772335/2013-10-08%2019.11.21.jpg

I think I need to replace the brass regulator in the picture. I'm guessing that it's clogged or something similar. That big brass piece is a "multi-seat" regulator from "Modern Engineering Co.", type P-I-DD. The grey piece is a Fisher Controls regulator type 912.

My first question is, why are there TWO regulators between the tank and the stove? The hose closer to the viewer in the picture is a vent, and the lower hose goes to the stove. Is the brass regulator just for the gauge? If I wanted to replace this entire assembly, can I just use a single regulator?

Here's a replacement assembly from Safgas: http://www.safgas.com/store/Boat-Stove-Parts/CNG-Boat-Gas-Regulator.html
Quite pricey, but similar configuration. Again, how does this work?

Thanks for any help!

We're a 5-person crew on a Catalina 34 sailing to Farallones then Drakes Bay starting this Thursday night, Oct20 to Saturday, Oct22. Any boats wanna join us as a buddy boat?

I'm rebedding my chain plates for the shrouds. After I remove everything and do all the work to get it ready to be re-inserted in the deck with caulk, I realize that the aluminum bushing around the stainless steel rod under the settee (which distributes some of the load to the hull) will not come off the rod. It's corroded very tightly together. WD-40 and hammering don't work. This causes problems for re-installation as I cannot get the chain plates rebedded with the rod in place since the angled aluminum bushing won't seat properly to the surface above it. Any ideas? (see attached photo in case my helpless explanation confused you).

I just replaced the trapezoidal Bomar forward hatch on my '87 C34 with a Bomar replacement from Pompanette. See this thread (I think I got the same one): http://c34.org/bbs/index.php?PHPSESSID=bbe89f2fb81fb6d52481f090caaff786&topic=1675.0

I (thought) I did everything right--remove the old carefully, repair/fill any holes, drill new, clean, seal (used 3M 4200), and secure. The new hatch is now in there and seems solid, but leaks readily in each corner on a hose test. I noticed, as did the above post, that the replacement hatch is just a tiny bit smaller than the old, and leaves larger gaps between the deck fiberglass and the hatch flange in the four corners.

Do I just need another go around with the 4200 sealant, especially in the corners? Will this stand up to heavy spray?

Since there are no drain holes in the forward part of the companionway hatch cover, every time I slide the hatch open when it's raining, a bunch of water pours into the cabin. I see that there are drains in the teak brace in the aft part of the cover. Has anyone tried to solve this by drilling two small holes in the fiberglass on both sides in the front of the cover? Anything I should know before I do it?

Thanks!
