My WB is at a slip all summer. I leave the centerboard down all summer with the exception of going into a beach. I still have the stainless steel cable and try and use it as little as possible. Just my two cents worth.
Peter: Our '95 original SS cable broke when floating the boat off the trailer and yes... it got stuck between the trailer's cross members. No choice but to haul it back out, take the mast down, trailer it to a lift, block it up and fix it again with a new stainless steel cable replacement supplied by Warren while visiting the Catalina factory in Florida this summer. It is thinner than the original and am not sure we entirely trust it. Consequently the up-haul is used as little as possible.
Good thing to have a spare cable on board, just in case, since getting the boat on the ramp or trailer with the center board in down position is no pleasure. We now have a factory (Warren) supplied spare Vectra line, (supposed to be stronger than steel) on board complete with new hardware should we have to replace the present thin SS cable.
In my opinion a little more dependable (read stronger) system could have been part of the original design.
I'll have to take the position in opposition to the others that have posted thus far. I leave the centerboard up.
Perhaps I'm in a unique situation because I grounded my boat long ago and damaged the hole through the centerboard. When I put it back together I opened the hole and epoxied in bronze bushings. With the bushings in place I have ZERO knocking of my centerboard. When I trailered my boat I would have to re-epoxy those bushings every two or three years because they would break loose.
However, leaving the board down, with the wakes of the idiots that don't know how to drive their powerboats through the marina, it doesn't take much time at all before the epoxy breaks loose. Then the board starts knocking like crazy.
With the board up, it doesn't get the forces from the wakes and waves that will break loose the bushings.
While a standard design centerboard doesn't have the same problem, the gelcoat and polyester resin in that hole in the center has to take some damage. I would expect that if you leave your centerboard down the holes will open up over time and increase the tolerances, and the knocking you will experience.
I have to chime in on Keith's side. While I havent had a swinger in years (Precision 21 - shoal keel swinger), the only time I had the c-board down was while sailing. At anchor or in a slip it was always up. Less wear on the hinge mechanism. Unless there's something diff/trick about the Catalina swings, if I owned one it'd be stored up.
As an aside, I'd also usually pull the board up when running for less drag. I can see the argument for reducing the wear on the raising system by just leaving it down all the time, but in my book that's just one more place where I pay a lot of attention to the condition and tend to run better-than-stock systems.
