Main Message Board / Re: chain plate studs and bolts; coax cable
« on: Yesterday at 11:36:45 AM »

1. i want to re bed the chain plates and re bed the studs (bolts) and nuts. What are the sizes and whats a good place to buy them?

Loosen one turnbuckle, remove the cover plate and remove one of the two bolts, washers and nuts, trundle down to your local hardware store (if it's a good one it'll have stainless steel fasteners, most stores do) and buy a dozen each.

In reality, I've rebed all of my chainplates over the years and never felt the need to replace those.

Looks more like uneven sanding of prior bottom paint layers than anything you've described as worrisome to you.  Perhaps a side view shot to see if there is any oil canning.

the goal is to replace the fittings.  the insides are caked with deposits.   the breather threaded elbow, i want to switch to a barbed fitting, i picked up an oil separator for that.  >>>>>>>>>>>>>>>>

I rerouted my breather hose to the top of the air intake.  I just turned the fitting from its normal "down" position to horizontal facing aft.  Pictures of similar retrofits are in the 101 Topics, which you most likely have seen.  I do not feel that a barbed fitting is necessary because there is literally no pressure involved in this hose. I just used a hose clamp over the hose on the threaded fitting.  Ron's idea to clean it has merit.  You'll also find that soaking it in full strength Simple Green (nasty stuff!!!!) will do the same thing.

I also suggest you reconsider including the oil separator.  Why?  Because the idea is to get the tiny, tiny amount of oil in the line to the air intake, rather than trying to trap it and now having yet something else to clean and service.

As far as threads for the pump outlet elbows, check with  Look up the Oberdorfer pump and find out the details there.  IIRC, Oberdorfer may also have a website with details of the pump or find it via Depco's website links.

I wouldn't sweat the 90 degree elbows, becasuse they are right at the pump, which can overcome their friction loss.  I've had elbows on my 1986 pump since our boat was new, they work just fine.

i am trying to stay away from wire wound wherever i can, if possible.  i've never been able to get it to cut cleanly and it always seems to rust and breakdown.  (or at least every wire wound hose i pulled out of the boat was a rusted mess).

The trick is cutting the wire cleanly when you cut the hose.

Have you considered that the "rusted mess" you saw was actually good news?  It was a "telltale" telling you to replace the hoses.

I've used wire reinforced hose on my two hose replacements over the years.  Never had difficulty with the 7/8" hose, and there's not much of it.  Order some online if you can't find it locally.

There's a link in the 101 Topics on exhaust hose replacement.

....also i do suspect the boat is not in cradle properly ,there is no blocking under keel.

Have you considered getting some shims and putting some blocking under the keel?

Could it be that the bow pulpit may be further forward than the anchor roller?

 Do you know how much clearance you have under your dodger?

The 101 Topics has this Dodger Height thread.  Mine's a low one, I'm 5-9, and it's around my armpit level, see the pictures.

Dodger Height 101 with Pictures and Links,7161.0.html

You can use page 4 of the brochure of your boat to see how high (or low) the boom is.

Do realize that when you raise it you'll be looking through plastic all day long; I just like looking over my dodger.  Mine is rare, though.

Good luck.

PS -  There's another 101 topic, Dodger Canvas you might look at, don't know if it's applicable.

23 years ago we just glued four small round pieces of felt below the top section of steps where they land on the bottom section.  Since they're in compression all the time, they ain't goin' anywhere!   :D  No idea what glue I used, but it was either the sticky back or maybe liquid nails. No need for anything special.

We never had any noise issues with the bottom section, it's so danged heavy.  I do always put a folded up piece of newspaper under the bottom section before I slide it down.  If that paper, a small edge of which we can see, ever gets wet, you betcha I'm taking a careful look.  I use it as a "telltale."  I also check the engine when we're running on a regular basis.  A standard piece of newspaper is almost a perfect fit, leaves less than a few inches at either end.

Water cooled compressors:  from extensive reading on Cruisers Forum and Kollmann, this idea has been reported to be less useful than many may think.  The additional complexity is reported to not be worth it, even in hot climates which usually have higher water temperatures, too.

I suggest that before anyone goes this route to do a lot of research.

Mick, there have been two or three places most compressor units have been installed in the Catalina 34 over the years:

1.  Lazarette
2.  Under starboard settee, forward of water tank
3.  Under forward section of starboard settee, just forward of the mast

This is for Mark I boats.  Mark II boats have their water heaters in a different spot than the Mark I boats, thus reducing the options, eliminating #2.

[Others have reported installations under the stove (!) and in the nav station hanging locker.  Rare, but reported.]

In the past 22 years I have never heard reports of insufficient cooling in the lazarette location, it is a huge space.

What we have heard, repeatedly, is that the other two locations REQUIRE additional ventilation.  This was true as early as the late 80s in tech notes for those skippers who had their dealers install the units down below instead of aft.

The compressor doesn't get hot, it's the condenser (the "radiator" with the fan on it), which is designed to remove the heat, and which can't work properly in a confined space.

The lazarette location is actually the best one on our boats.  It doesn't need anything else.

My boat is almost 34 years old and we've owned her since 1998.  Other than replacing the electronic module in 2016, it is the original unit and has been working just fine in the lazarette.  I have sailed in the California Delta in over 95F daytime heat for many summers.

The VERY LAST THING you ever want to do is let any water into the lazarette.

For those of us who have our boats in Maryland but live outside the state, I would appreciate hearing reports here from anyone who encounters difficulties from law enforcement regarding Maryland's quarantine requirements for those coming from out-of-state. My hope is that Maryland will consider us to fall into the "regular commuter" exception, but I am not aware that this exclusion has been tested.

Often multiple sources of info may be helpful:

See #256 and later posts.

Good luck.

Sweet.  I miss that swell.  Great feeling as you work with your legs and stay stabilized.  Once, coming downwind from the Ocean through the Golden Gate, I had a magical hour with batches of dolphins off our port quarter, sitting on the port perchseat.  Heavenly.

Thanks for the photos.

ba, go to the tech wiki and download the brochure of your boat, usually on page 4 of the brochure.  That page includes a drawing of the profile of your boat.  I use that and give a copy to the sling hoist crew.  It's easy for them to line up with the portlights and stanchions.

Go here:

It's the main tech wiki page, first paragraph, click on "several models."
