Stupid question probably, but I am on a mission to replace everything on this 1991 Nacra 5.5sl that I am worrying about it's age and longevity. I've replaced all mission-critical stuff like shrouds and stays and lines but now you have me thinking about this. How do you know when to replace the bearings or is it just an "ounce of prevention" item? Do you replace them regularly? I am sailing this exclusively in fresh water and so I assume my requirements for replacing would be different that yours?

Thanks
Greg
