Hi!I am new to sailing. I bought a Macgregor 26S in July 03. That hooked me and I bought a 1989 Catalina 30 last November. The boat was well taken care of by the previous owners but with 1 year under my belt and with a number of relaxing and sometimes invigorating sails over the past year I am wondering if I have gotten myself into more than I can handle. More specifically, how do you know when things such as the standing rigging need servicing. Also, what about the driveshaft packing gland, the cutlass bearing, the thru-hulls, when and how to check on/change the driveshaft zinc without hiring a diver, etc.?? I can handle the basic engine maintenance but I have read that the standing rigging is good for 5-10 years and then should be replaced. Is that true? How do you know when the packing gland and/or cutlass bearing need to be serviced without having the local marine mechanic look at it, who oh by the way is the one who will benifit from recommending servicing.Don't get me wrong, I am at least more handy than most at working on mechanical systems (I'm an engineer) and maybe i'm just overwhelmed but can any of you folks with more years under your belt lend any insight as to how to handle some of the issues I have raised?Thanks in advance!Don
