David,
Vendor changes are usually not associated with conspiracy theories...in engines alone, the 320 has been equipped with Perkins, Westerbeke and Yanmars...on cuba libre 2--#112, I thought the Perkins was a fantastic engine---it's all about margins on boatbuilding...vendors fall over each other to get their equipment spec'ed on boats by builders like Catalina, Hunter, Beneteau...
As a builder, you get some huge economies of scale by using as many of the same types of products across your product line...
Every few years, everyone changes preferred vendor, it's all about cost accounting...

First of all, to Bob, I will indeed be sure to pass along anything I
learn from Charleston Spar, Catalina, etc.
I also thought some of you might appreciate the irony of the story of
why I have an in-mast system. When I purchased (ordered) my 320 at the
Boston Boat Show in Feb. 2005, my intention was to order a regular mast
with the Dutchman system. However, at the time, Catalina was offering a
"boat show special" which included a couple of freebies, including free
mainsail furling, if you bought at the show. My broker and his boss
tag-teamed on me to convince me that I would be foolish not to take
advantage of the offer. Regrettably, I went along with their advice.
Finally, to Dennis, I appreciate your input. My plan is to give my
broker a day or two to see what he can do for me. But then, if I am not
satisfied with his progress, I will certainly go directly to Charleston
Spar myself, and then Catalina too if need be.
I also had previously given a lot of thought to your point about all of
the other Charleston Spar in-mast systems that have been in use on lots
of other 320's. I admit that I have never seen this issue referenced on
this site before; and that is exactly the reason for my original post
about this problem - to see if I could draw out any others who may also
have experienced it. We'll see. Maybe I am unique. But if I were a
cynical person, I sure might wonder about the switch to Selden with the
Mark II.
Thanks for your interest.

Dave, Robert,
Regarding the narrowing of the mast groove on your in mast furling
systems,
why don't you contact Charleston Spar directly at 704 597 1502 and talk
directly to them regarding the problem. If it is a serious problem,
they
probably have a fix for it, and perhaps a fix even if it is not a safety
issue. While my own mast is the conventional one with full batten sail,
Catalina has been using the in mast furling system for many years now
(it
was available in 1999, and not sure how much earlier it was used). The
same
basic design appears to be used on lots of models other than the C320.
With
the large number of subscribers on the C320 list over many years, if
there
was a serious safety issue (as in mast failure), it would have come to
light
well before now. Therefore, I believe you can feel confident that the
mast
is not going to fail in normal use (assuming it is rigged correctly).
Since
the masts are aluminum extrusions, it is probable that the same dies and
metal composition have been used for all boats using the C320 cross
section.
It is not likely to be a quality control issue, but a design issue.
Where
the spreaders join the mast is point of high stress. Aluminum is a
ductile
metal, and if overstressing is not too extreme, it will tend to deform
(flow) locally to releave that stress ....that's what I believe has
happened
here. Still not very comforting and it shouldn't happen.
Jack, as to Catalina switching to another vendor for masts, it probably
has
to do with who had the best bid for the job. Charleston Spars are used
on
lots of boats, not just Catalinas. Your mast gate problem seems minor
compared to the above concerns, and if you get the gate plate adjusted
properly and raise the sail by heading into the wind, with just a little
pressure (sail) to the side away from the gate opening, that problem
will go
away. Not a reason to switch from one mast manufacturer to another.
Hope this helps.
