I knew I could count on you for valuable input. Thanks.
So would it be correct to say that, all things being equal, all that pounding at sea is going to cause more fatigue damage to fiberglass than to steel? Is metal fatigue even a real worry? From what I recall from mechanical engineering 101 the forces involved really aren't large enough to cause a fatigue failure on a steel boat. If they're not then it seems safe to say that as long as it is kept corrosion-free it will pretty much be as strong as it was when it was first launched. Is this correct?
So anyway, how do boats get pronounced dead? Do they simply come up for survey and get declared to be more expensive to fix than to replace? Or do they just split in half and sink?
