Re: Stus-List 33 mk2 Mast step loads

[Russ & Melody via CnC-List]

Hi Dave,

Watch those units.
4000 PSI on a 6" x 8" mast step plane is out of this world for a 33 foot boat.
When I did the mast loading while designing the 
rig of my old 60' cruiser it was 100,000 lbs and 
he's telling you it's twice that??


I would go with Joe's suggestion of 1/2" aluminum 
plate and move on to other projects.

Thanks everyone for the info. I spoke with Danny 
from Klacko spars yesterday and he's certain 
that he would have installed my original mast in 
'87. He figures even when falling into a wave 
with full sails the forces wouldn't exceed 4000 
psi. Seems light to me but who am I to argue with him.
I thought I notice Mr. Knowles at the club on 
the weekend so I'll definitely run it past him - thanks for mentioning that.


I have the entire mast step "excavated" to the 
keel and am starting the rebuild. Can't wait for this one to be finished!


Thanks!

Hi Greg,

You can research the righting moment, at say 30 
- 33 degrees, for various boats in your size 
range for a second opinion. The 33-2 is similar 
in stability to my 35 mk-1(check diagram in the 
Technical Info on Stu's CNC site).


I put the load at about 10,000 lbs, so building 
for 12 - 15,000 lbs is not a unreasonable. If 
you're going with aluminum only then I would 
spec it at 20,000 for a 50% corrosion allowance 
and say, "I expect this to last another 20 years."


BTW, check with Rich Knowles on my credentials, if in doubt. :)

Hi Rich, we miss you on the Left Coast.

Re: Stus-List Stuffing Box on 1986 C&C 33 mk2

[David Kaseler via CnC-List]

Someone with more knowledge than I should help you with this but you should 
understand that traditional stuffing boxes are designed to leak. The water 
keeps the unit lubricated and cool. I now have what they call a dripless 
stuffing box which is a completely different design to accomplish the same 
thing. As I remember my traditional stuffing box dripped about like yours when 
the shaft was turning but not when it was not.

Re: Stus-List Chart plotter mount for boat with a tiller

[David Kaseler via CnC-List]

I need to put in my two cents. Many years ago we had a Newport 27 with a depth 
sounder mounted on a hinged arm. The mount was inside the cabin but could be 
swung out so the display was in the center of the companionway. Because the 
unit was mounted on a plate that swiveled it could be viewed from below or from 
the cockpit. This unit was custom made by the prior owner but I have seen 
similar units available commercially. In this case the wiring was just lead 
along the arm and was always secure no matter what the position of the depth 
finder. The only draw back was that you had to swing the unit out of the way to 
go up or down the ladder. If I were in your situation now I would use this 
solution. Actually, I have given it some thought for my small chart plotter/GPS 
but I'm so addicted to paper charts that I seldom use the electronic except as 
a backup.

Re: Stus-List Chart plotter mount for boat with a tiller

[Jeremy Ralph via CnC-List]

Thanks Matthew and Dennis for the input.

This is the mount I've ordered:
http://www.rammount.com/part/RAM-D-111U-C

I was talking to someone who was unhappy with their swing out RAM solution
for the following reasons:

1. The positioning interferes with getting in and out of the cabin.  Having
it on the companionway slider would interfere with cabin access too though,
but even with the companionway slider fully open I can still see the chart
plotter from the helm so it might not interfere as much.  With it on the
slider, though, I can't view the plotter in the cabin... but I don't expect
to need it in there and the plotter connects to my iPhone which I can use
in there.

2. Can't close the companionway in bad weather (or, also, in my case to
keep the kids from falling down there...)

Cheers,
  Jeremy

Stus-List Stuffing Box on 1986 C&C 33 mk2

[Brett Robertson via CnC-List]

Hello and thanks for taking the time to read and respond.  I’m a new owner of a 
1986 C&C 33 mk2.  My stuffing box is leaking/dripping.  I’d say a drip every 3 
seconds.  I’m going to try and see if I can tighten it, but I briefly tried and 
it was very difficult…maybe due to corrosion.   Plan is to try again after some 
PB Blaster or other compound to assist in loosening.  I don’t know when the 
stuffing was replaced previously.

Looking for some help in selecting the correct stuffing/packing size.  I 
believe you select the diameter of the packing material according to the shaft 
size???

Many thanks for the help, any suggestions would be appreciated.

Re: Stus-List 33 mk2 Mast step loads

[Dave via CnC-List]

Have been thinking about your post Greg.
Remember, the 33-2 mast step is not only compressed by the mast, it also bears 
the compression load of one of the four large keel bolts.   Don't only think of 
the rig  
Fellow lister Doug A quite wisely convinced me to install compression posts 
when I rebuilt my keel, and the pro repair by Bristol marine here in Toronto 
does the same.

Dave.

Stus-List Chart plotter mount for boat with a tiller

[Jeremy Ralph via CnC-List]

Hi All,

I've bought a new 9" chart plotter for install on my tiller steered C&C34.
  The boat has a small companionway dodger.

I hooked the plotter up and experimented with some possible locations.  I'm
leaning toward mounting it on a RAM mount on top of the companionway
slider.  What I'm not sure about is how to deal with the wiring...   Some
options:

1. Have wires go onto top (exterior) of slider with enough length to open
slider.  When slider is open wire slack would bunch on top of slider.

2. Have wires come up through bottom of RAM mount.  Wire slack would bunch
in cabin when the hatch is closed.  (Wires come out of cabin liner near
companion way)

Any recommendations from the group?

Thanks,
  Jeremy

The heat exchangers are made of a copper-nickel alloy which is also commonly 
used for all types of saltwater interfaces in the power generation and military 
industries.  No anodes are required.  Anodes are required in a raw water cooled 
engine because there is no way to prevent the saltwater from touching the cast 
iron engine blocks.  Similarly in the military and industrial heat exchangers 
the shells are made of carbon steel and as a result anodes are attached at 
those locations.
As for our freshwater cooled engines the cast iron is protected by the cocktail 
of chemical additives in the glycol coolant.  The coolant also has lubricants 
to help protect the waterpump shaft seals.
In the freshwater versions of our engines the block is exactly the same as the 
raw water counterparts.  The anode ports are simply plugged with a screw in 
pipe plug.  This provides an opportunity to install a block heater to keep 
condensation from accumulating during the off season.
I had stuck rings one year and I've kept a block heater ever since with no 
recurrence of the stuck rings.

Hi Greg,

You can research the righting moment, at say 30 - 33 degrees, for various
boats in your size range for a second opinion. The 33-2 is similar in
stability to my 35 mk-1(check diagram in the Technical Info on Stu's CNC
site).

I put the load at about 10,000 lbs, so building for 12 - 15,000 lbs is not
a unreasonable. If you're going with aluminum only then I would spec it at
20,000 for a 50% corrosion allowance and say, "I expect this to last
another 20 years."

BTW, check with Rich Knowles on my credentials, if in doubt. :)

Hi Rich, we miss you on the Left Coast.

Cheers, Russ

Thanks everyone for the info. I spoke with Danny from Klacko spars yesterday 
and he's certain that he would have installed my original mast in '87. He 
figures even when falling into a wave with full sails the forces wouldn't 
exceed 4000 psi. Seems light to me but who am I to argue with him.
I thought I notice Mr. Knowles at the club on the weekend so I'll definitely 
run it past him - thanks for mentioning that.

I have the entire mast step "excavated" to the keel and am starting the 
rebuild. Can't wait for this one to be finished!

Thanks!

Re: Stus-List Zinc in heat exchanger, Yanmar 3JH2e

[Josh Muckley via CnC-List]

The heat exchangers are made of a copper-nickel alloy which is also
commonly used for all types of saltwater interfaces in the power generation
and military industries.  No anodes are required.  Anodes are required in a
raw water cooled engine because there is no way to prevent the saltwater
from touching the cast iron engine blocks.  Similarly in the military and
industrial heat exchangers the shells are made of carbon steel and as a
result anodes are attached at those locations.

As for our freshwater cooled engines the cast iron is protected by the
cocktail of chemical additives in the glycol coolant.  The coolant also has
lubricants to help protect the waterpump shaft seals.

In the freshwater versions of our engines the block is exactly the same as
the raw water counterparts.  The anode ports are simply plugged with a
screw in pipe plug.  This provides an opportunity to install a block heater
to keep condensation from accumulating during the off season.

I had stuck rings one year and I've kept a block heater ever since with no
recurrence of the stuck rings.

Re: Stus-List Zinc in heat exchanger, Yanmar 3JH2e

I went through this when I first got my 37/40. Apparently the metallurgy of the 
exchanger precludes the need for zincs. In any case I've never found any on my 
3JH2E.
