In response to a question that was posed on the Catalina 320 list by a prospective buyer of a
Catalina 320 looking for problem areas to be aware of, I wrote the following
response. This response has been refined by input from others and has been
improved from the original email for publication.
Due to the length of the material, it is being broken out into two blog entries. See Part Two in a future entry.
Catalina 320 Review and Known Issues
By Doug Treff, September Song, Hull 350
In my opinion, the Catalina 320 is a fine vessel for the
purpose that it serves me - cruising the Chesapeake Bay. As with any boat,
there are pluses and minuses with the design.
Every boat design is a compromise of form and function. I believe that
Catalina hit a home run with the 320, and its continued popularity, even after
being replaced by a newer model, bears that theory out. The strong C320 owners
association adds value as well, since we all share ideas and solutions to
problems. Below is a list of things I love, things I don’t love, common repair
issues, and design flaws for the C320.
Things I Love:
- The Aft cabin - Having the Aft cabin really
makes a huge difference in the amount of space onboard for accommodating
guests. It also offers more privacy than other boats without this feature. At the 2015 boat show in Annapolis, I toured
the current models. The 315, which Catalina considers an equivalent new model
to the discontinued 320, does not have the same size aft cabin. You need to
move up to a 355 to get a similar aft cabin now.
- It's competitive compared to other models - I am
continually amazed how I can hang with larger boats when out sailing. Boats
that should have a speed advantage due to sail area and waterline length, yet I
can keep pace with them.
- The Cockpit is comfortable and roomy for
entertaining, and the large wheel makes it easy to sit outboard and see around
the cabin while steering the boat. Bonus - the walk-through transom.
- A full shower in the head - This is my first
boat with a shower and it was a huge selling point.
Things I Don't Love:
- Side-loading aft berth - Whoever sleeps closest
to the door to the aft cabin will be disturbed when the other person needs to
get up in the middle of the night for any reason. Unfortunately, in this size
vessel, there's no other way to design an aft berth this large.
- Cabin Storage Space - There is limited storage
space on the boat. Due to the location of the batteries and sewage tank, the
starboard settee is not very useful for storing things. I would never put food
in there and you really shouldn't pile a lot of stuff around the batteries.
- Sail handling locations - When single-handing, the
helmsman will need to leave the helm completely to tend the main sheet due to
its location on the cabin roof. I recommend that every C320 owner make it a priority to properly rig the reefing set-up and practice using it so they can do it efficiently when needed. I recently discovered that my traveler control lines are long enough to reach back to the helm area. When things get heated, I make a point of making sure the traveler lines are led all the way aft where I can reach them from the wheel. This makes it easy to dump the main in a gust and keep things under control. I generally don't like Hunters but one of the
things I've admired about them is the arch with the main sheet right at the
helm station. The same comments apply to the Jib sheets. The primary winches need
to be about 2 feet further aft for handling by the helmsman.
- She rounds up easily - Due to the very wide aft
cross-section, when the boat heels too far, the rudder loses effectiveness,
causing the boat to round up, often resulting in an unexpected tack. Especially
troublesome when considering the other problem regarding sail handling. If
single-handing, you cannot dump the sails quickly while also tending the wheel.
The solution is keeping heel angle under control through sail trim, and reef
early. See my note above about keeping the traveler lines handy.
Common C320 Repair
Issues:
There are very few inherent problems that span across all
C320 model years. During the production run, Catalina made changes to their
design based on customer feedback. The 320 is a good example of a reliable
production boat and many survey problems are due to poor or deferred maintenance.
Below is a list of known problems and issues that has been pulled from
monitoring the C320 list for a number of years. It will give you a good check
list.
- Early models of the C320 did not have solid
fiberglass in the deck around the chain plates to protect the core from water
leaks. Sometime later, they started doing solid Fiberglass in these areas.
Nobody has been able to definitively state when that change was made, so
exercise caution here and address chain plate leaks ASAP.
- Stemhead fitting – There is a known flaw in the
design of the original stemhead fitting which could lead to rig failure if a
crack develops. The stemhead fitting on all C320s should be examined closely
per the article here. It might be wise to share the following information with
your surveyor. http://www.catalina320.com/filemgmt_data/files/Stemhead%20Article.pdf
- Sewage tank vent design flaw – Catalina uses a
5/8” vent fitting on a ¾” hose. The vent is too small and the screen often
clogs. Easy to fix, but this can cause all kinds of holding tank problems due
to poor venting of tank. See the association site for a fix to this issue.
- Older 320's may need a fuel tank replacement. If
you search the 320 forum, you'll find discussions of fuel tank leaks over the
years. Consensus seems to be 15-25 years is about when the failures start in
Catalina aluminum tanks. Replacement tanks are available and they DO fit in and
out of the boat without cutting any fiberglass.
- Slow water leak from Aqua-Lift muffler box -
You'll need to have your mechanic check for this during the sea-trial. Not a
huge amount of water, but it can contribute to an exhaust odor in the cabin over
time.
- Recent reports of failed refrigerators have revealed that there is a possibility of the fridge compressor being damaged by rainwater leaking from the propane tub above. Be sure to closely inspect the compressor - located on a shelf in the aft port locker. If you find any signs of rust or water drips, be sure to look carefully at the propane tub and the connection points where wires and hoses pass through it. Also, make sure the water drain pipe of the propane tub is not clogged. When the propane tank is present, it takes only a small amount of water to fill up the propane tub and then it overflows.
Design flaws – other
issues:
- Port List – Not every boat, but many C320 owners
have noticed a slight list to port. This could be different from one boat to
the next depending on installed options like air conditioning, or extra
batteries.
- 1996 and older models do not have a molded toe rail aft
of the cabin. This is a safety issue and I have already nearly gone overboard
twice because my foot slipped right off the boat. This issue was rectified with the 1997 model year.
- Early models (1995 and older) had a shallow
bilge. The deeper bilge is more desirable if you can find one.
- Rudder depth - On the shoal-draft (wing keel) models, the rudder depth is the same as (some claim it is deeper than) than the keel. Nonetheless, if you have the shoal-draft (wing keel) model, be very protective of the rudder in grounding situations. Rather than powering through, it would be advisable to try and back off any grounding you encounter.
As you can see, no boat is without inherent design flaws and common problems. Don't let this list scare you off. The majority of the C320 fleet out there today is well-loved and cared for. Hopefully, you now will be better armed to uncover some of the common issues.
