Frequently Asked Questions...
Engine Temperatures - I saw a post about the Harbor Freight laser thermometer and I had just bought one so I thought I'd post my initial readings from my M18 just to have them out there for a baseline for comparison. I'd like to get the temperatures again after running the engine underway for an hour or so, but these numbers were after running in the slip for about 20 minutes at about 1200 RPM with the transmission in reverse. The ambient water temperature was 89.9 degrees and it was near 100 degrees outside air temperature. Temperatures are in Fahrenheit.

Rigging Tension -
Here is the generic advice for masthead rigs that my
rigger gave at a recent seminar on rigging and tuning. (Tensions in
lbs. for the C-30 rigging is given in parentheses.
Stays and Upper
Shrouds
18-20% of wire breaking strength (1/4" 1x19 B.S. = 8200# x 18%-20% > 1476# -
1640#)
Forward Lower Shrouds
1/2 the percentage of upper shroud tension ( 3/16" 1x19 B.S. = 4700# x 9%-10% >
423# - 470#)
Aft Lower Shrouds
1/2 forward lower shroud tension (212# - 235#)

Stuffing box repacking -
Is this a job that anyone has
tackled whilst still in the water or is
this something that should only be done when dry docked?

Very easy to do in the water. Obtain the new material (I like the Tefpack Synthetic Packing - available at WM)and some anti-sieze compound (available at any auto parts store) and proceed as follows:
| loosen the gland nut and slide it back on the shaft as far as it will go. | |
| using a half hook shaped pick, carefully remove all of the old packing. make one out of a thin wire coat hanger, cut it to 6 inches, bend it like an L, open the L a bit, sharpen the point and pick away. The incomming water will usually wash out the small pieces. Be sure to get all the old stuffing out. | |
| wrap the new stuffing around the shaft and cut with a razor blade where they meet. There should be no gap or excess. I overlap an 1/8" and cut thru both pieces on a straight line to be sure they are an exact fit. Cut three pieces this way. | |
| Insert the packing pieces into the stuffing box, one at a time and push in as far as possible using a push stick, a popsicle stick will do fine. The pieces must be inserted at 33 degree offsets, say 12, 4 and 8 on a clock face. | |
| apply anti-sieze to the shaftstuffing box threads and slide the gland nut forward and tighten lightly, just more than finger tight. Be sure to use two wrenches, one to hold the stuffing box, one to tighten the gland nut. | |
| Start the engine and put in gear at idle. (this can be at your dock, just be sure the boat is tied well) Tighten the gland nut until you have one drop per 30 seconds give or take. | |
| After motoring for an hour or two, recheck and retighten if necessary, and check again after another 5 hours or so of motoring. |

Barlow winches?
I just found a table on-line (http://www.kiwiyachting.co.nz/products/barient.htm)
that compares Barient and Barlow winches to Lewmars. It doesn't show a
Barient #23, but lists a Barlow 23 (Barient 21) as being equivalent to a
Lewmar 30. Apparently Barient/Barlow used a different model number
system than Lewmar, Harken and Andersen use today.

Suggested Spares and Tools
A few days ago I asked what tools and spares that folks
tended to keep aboard. I tried to edit the list of those responses so they
wouldn't be repetitively redundant over and over again. Sounded like with vise
grips, duct tape and a Dremel you could pretty much build your own boat. But
some folks also suggested these things as well:

this before?
Many C30 owners have made this partial or full upgrade
or switched from end boom sheeting to mid boom. Here is one experience from Ed
Rheimbold, who has done excellent work on his boat. Also check out the pictures
on the C30 ftp site - look for "Troika". (Click here)

How do I know which
Kubota engine I have?
Universal diesels are Kubota tractor engines. You just need to know the Kubota
model number that is stamped on the dipstick. The following are Universal

What
about the pipe stems?
This is a really old one - I didn't think anyone still had the pipe
stems! Since I'll be on the hill next week for topside paint, I thought it'd be
a good time to ask a few general preparation questions. First, I still have the
original thru hulls. The ones that are like basic water spigots. None of them
shut-off anymore. What is the recommended replacement? Also, what other items
should I be prepared to inspect/repair. It's basically coming out for painting
but I'd like to make sure I catch anything else that needs catching. Since I'll
be at a rather remote location, a good distance from a marine supply, I'd like
to have any foreseeable materials on hand. Any input would be appreciated.
YES! replace the whole works! I am surprised the gate valves have lasted this
long. And that the pipes have not worked loose and leaked before now. Not one of
Catalinas finest manufacturing details. The pipe stems were inserted in holes in
the hull and glassed into place. Worse, the factory put ordinary gate valves on
the top! Any attempt to tighten the valve bodies on the stems usually resulted
in twisting the pipe loose from the glass, and OOPs a big leak.
I highly recommend installing MARELON thru hulls in every location. Do them all
now. And then install MARELON seacocks at all locations thereon. FORESPAR makes
a line of such devices. Mine have been in place for 15 years with no sign of
wear or damage from all my in hull junk!
Probably a good time to check the shaft and prop for wear and to replace the
cutlass bearing. Is your bottom already protected by epoxy barrier coat?
Is there any slop in your rudder shaft?
Is any stained water leaking out of the rudder body?
Time to switch to an ablative paint!
Clean and lubricate all other thru hulls, speedo, depth, head discharge!
What
is Jiffy reefing?
If you go to
http://www.catalina30.com/PartsManual/PartsManual.htm
and look at "spars and rigging", on page 7 of that section there is a
picture of the setup that will be worth a 1000 words.
Not specific to a C-30, but the first site is a
good one (this boat is set-up for a double slab).
http://home.earthlink.net/~chrisbeatty/wsnC489.html
The second site shows the general parts of a main and the
reefing procedures.
http://www.pineapplesails.com/articles/reefing.htm
Remember: the short reef ties in the sail should only be used to gather up
the loose sail after the halyard is re-tightened up. You'll rip the
sail if you try and control the foot tension with
them. They really aren't even necessary.
If the sail is loose footed like the one on the first site above
they shouldn't wrap under the boom, they should just gather the sail and
be tied over the boom (with a square knot (aka reef
knot)).

Replacing Lifelines.
I have replaced lifelines and fittings on all three
of my boats within the past 4 years. It is very
easy to do with the Johnson hand swag fittings and
Johnson swag tool (they say DO NOT use the regular swag
tool). The Johnson swag tool is about $35, most of the Johnson
fittings are about $15 (or less, depending on
fitting), and the "good" pelican hooks are about $40.
Price the fittings and price the number of feet of
lifeline you need (from the Boat US/West/Sailnet they are about $1.20 per
foot) and that will be your cost. It will
take you about 15-20 minutes per fitting to make them
up. DO IT - you will save lots of money and
have the satisfaction of doing it yourself.

How do I replace the cutlass bearing? This subject has grown to the point it needs its own page to describe... click here
And a handy "make it yourself" tool to remove/replace cutlass bearing... click here and a reversible model click here...
AND... How
do I remove the shaft from the transmission coupling...
The major difficulty is access to the transmission
coupling and the difficulty in removing it from the
shaft! Too many years of just sitting there will have
bonded the shaft/coupler by slight corrosion.
Start by separating the two halves of the coupling (four bolts) and
removing any set screws or clamps on the shaft.
Also loosen the shaft seal device.
The basic technique is to then force the shaft out of the coupling
with liberal use of lubricants, penetrating and otherwise.
This can be done by using varying length
"sockets" between the shaft and the transmission and
by slowly squeezing the coupler halves back together.
I used 3 different length bolts to tighten the
coupling halves. I always used all four bolt holes so
as to equalize the "push" without distorting the
coupling halves. After a while it will go easier!
Once the shaft is out of the boat, you can get at the cutlass bearing.
You may be able to force it out with a ram of some kind. I had to cut
thru mine with a hacksaw - just thru the rubber and the very thin tube
- don't cut into the strut body! After
that, its all clean up, sand all the orifices, do a
test fit and then lube, reassemble and replace/tighten
all bolts, set screws etc.
You might want to consider replacing the old shaft seal with a newer
dripless style like PSS while you are at it. Some people also install
a "drive-saver".

it re-passivates the surface and cleans and
polishes at the same time. The
Wichinox even adds a phosphate to the iron and it can't rust until the
coating is worn off by some other chemicals that are more active like
sodium and chlorine (SALT in water
solution)

Those Leaking Windows...
From time to time there have been many questions about
how to deal with those leaking windows in our boats. Where does the water come
from, what damage has it done and how do we fix it? Most of the time it is a
very simple fix, then sometime, you must remove the entire window. Removing the
window is really not that difficult, just take your time and do not, muscle it
out.
Following are techniques for a Simple Fix and a Complete Fix.

What can I do to match the

Flex_mold has patterns to match the deck. It matches
perfectly. However, its almost impossible to get it to mesh with the existing
non-skid but when its done you don't even notice. The company is:

The pattern for our vintage of boat is GFCW 317 Catalina Basketweave. I bought
a piece of it 2' X 2' for $52 which, at first, I thought was highway robbery but
I tried to make a negative of the pattern first with silicone and then with
glass and resin ... just made a mess and it didn't work at all. This stuff
works great.

I just had my mast pulled to have it
rewired, new lights, etc. When the mast was stepped the boat yard was supposed
to tune the rigging. To my surprise, he just tightened everything loosely and
said that you have to adjust them under sail.
First of all make sure the yard put the rig up right.
Check all wire and devices for breakage or wear. Turnbuckles should turn freely.
Did you or the yard inspect all pins, bolts, swivels, wire and swages for signs
of rust or wear?
Using a halyard or a long metal tape (from the masthead) you should measure to
several points along each rail and make sure the mast is equally in the middle (athwartships)
(sideways) of the boat. Our oldest advise is to make the mast stand straight up.
A main halyard with a weight attached can be used as a plumb line to determine
the "rake" of the mast. How far it tips forward or aft. Actually, I have my mast
raked back 5 inches and this really helps pointing without adding noticeable
weather helm. Then you have to go sailing. About 10 knots is nice. Smooth water
is best.
Close hauled on equal and alternating tacks you should slowly
remove excess slack from all shrouds. Check your wind instruments at the same
time. Eyeball the mast track or the front edge of mast. You must keep it
straight at all times. Tighten the uppers first, a little bit (half turns) on
each side on each tack. Then adjust the lowers so there is no "S" in the mast.
Overall, the forward lowers should be tighter than the aft lowers. A slight prebend,
tightening the lowers against the backstay, will help flatten an old main. On
each tack a slight relaxing of the leeward shrouds is fine, means they are not
too tight! Sorry we do not have any Loos gauge numbers or precise pressures.
Install a backstay tension device to help reduce head stay sag on upwind legs. At least once a year, you should turn, adjust and lubricate the turnbuckles to prevent seizing and galling. Don't forget the furling drum. A anti-seizing compound or lanolin is best. It is water resistant and can be forced down the top of swages to prevent water entry. Don't use WD 40.
If you have temperature extremes and leave the rig up all year, remember that the coefficients for stainless and aluminum are quite different. The mast shrinks less than the wire! So you may have to loosen things as it gets colder and vice versa! Max Munger

Any safety or re-engineering of the backstay ever required? Are the same wire sizes and turnbuckles still used? Apparently several C30 in New England have had near backstay failures from galling or striping of the threads on the single backstay turnbuckle. Reportedly, because of the short season, corrosion was not a factor. The older C30s have split backstays with a single turnbuckle just above the split.
About 1990 the factory switched to (longer?) splits with two
turnbuckles, one on each of the splits. I assumed this was done to accommodate
the walk thru transoms. My reasoning was that since the split was raised higher
above the deck, that the lower turnbuckles could then be reached.
The old style turnbuckle bodies were stainless steel, which could gall if over
tighten or cross threaded. The failures are probably age-related. Standing
rigging should be replaced after 10 years use unless the boat is in fresh water
or hauled and de-rigged in winter. There never was any re-engineering of the
backstay other than raising the split so you could walk under it. The wire and
turnbuckles are the same size.

"According to my paper work the hull identification number is "CTYN0773M77L". What does that mean?" The hull numbering, as required by the USCG, contains 12 characters; 3 groups of four. The first four are manufacturer and size, i.e. CTY for Catalina Yachts and "N" for 30, "L' for 27, etc. The next four are the serial number of the boat (only the C22 exceeded the four spaces allowed with 16000 boats built-we dropped the "1" at the front). The last four are the year of manufacture and/or model year. This coding changed over the years.
If your boat has the old number system. The first "M" means modified. The next two digits are the year built. The final "L" is the month "July" in the modified system. The later system started with an "A" which is Jan, "B" is Feb, etc. The second number is the year built (4=1994) and the last two numbers are the model year (95=1995)
C30 # 049 was built in Woodland Hills in 1975. C30 #315 is a
1976. Your C30 #773 is a 1977 . As you can tell by the jumps in the numbers,
Frank was cranking out a lot of C30's back then. Your members can e-mail me at
catalina@catalina.net if they want to know what year, etc. their boat is.
