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
18-20% of wire breaking strength (1/4" 1x19 B.S. = 8200# x 18%-20% > 1476# -
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:

Any hints on replacing the diesel exhaust hose?????
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. Bryant Pratt, Great Salt Lake, Utah
Barient winches on my C30. I know they were purchased by Lewmar some time
ago! Where can I get parts?
Florida Rigging @ 1-800-718-1649 is probably your best bet for Barient service
and spare parts.
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: (See Suggested Spares and Tools) Steve Paxton email@example.com
considering installation of the full C30 Garhauer Upgrade kit. Has anyone done
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)

I show the C30 at 6.80 gross tonnage and 6.12 net tonnage. David Graas - Catalina Yachts Technical Support. Also Max Munger's 1981 C30 certificate shows gross at 8 tons and net at 7 tons!
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 Marine/ Kubota tractor diesel designations:
M25XP D-950 the engine number off my dipstick is 5377-36412

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!
is Jiffy reefing?
If you go to https://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).
The second site shows the general parts of a main and the reefing procedures.
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)).

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.

Plasteak, Inc. in Akron, Ohio, can make any boat parts if you send them the old part as a pattern. Plasteak will never rot, etc. We had dock mates in Ohio that used them for the slide hatch pieces and we could not tell the difference between Plasteak and real teak on his C25.

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...
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".

This oft asked question has its own page now... (Strut repair)
If you use "Wichinox" WM2001 page 967 SKU 367641 $11.99 on the SS 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)

What does Catalina use to "finish" the interior teak? The varnish is Target Coatings-Oxford, semi gloss. If your boat is oiled it is Watco teak oil. Gerry Douglas

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
Following are techniques for a Simple Fix and a Complete Fix. (click here for the complete story)
What can I do to match the
non-skid pattern on the deck for some repairs.
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:
Fort Worth, TX
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

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
firstname.lastname@example.org if they want to know what year, etc. their boat is.
