What's critical to check....

[FrankLanger]

I'm sure we all think our boats are in pretty good shape, and we check them periodically, especially in spriing/fall, and have our "to do" lists. However, I'm wondering what items on a boat you would suggest are "critical" to check and perhaps even repair/replace before there is any sign of a problem developing, to minimize getting stranded or other problems.

The ones that come to mind for me "off the top of my head" are:

1) Replace the water pump impellor every couple of years--cheap, easy and could prevent engine overheating

2) Replace zinc anodes at regular intervals, even if they aren't used up (most people suggest that you should replace when they are 50% or so used up)

3) Check shrouds for any fish hooks, cracking at the swage, and replace periodically (there is lots of discussion whether this should be every 7 years, 10 years or 15 years, depending on where you sail, etc.)

4) Check running rigging/replace when there is sign of chafing, etc.

I'm sure there's lots more, but what do you folks think is "critical", especially the "hidden" areas (like an impellor) that one might overlook, and regret later.

Chainplates, rudder stock bearings, gudgeons and pintles are all static fixtures that should be periodically examined for degradation. Particularly in the way in which they are secured and the underlying structure they are secured to. Anywhere that hardware penetrates the deck or hull should be checked periodically for signs of delamination or weakening.
