Re: catalina27-talk: Shroud connections to the hull

Bob, I think we are all practical engineers of sorts.  I think I have to say what you propose would be pretty hard to do.  Rigging fails at given places, usually due to failure from weathering, deterioration from chemical action, or mechanical weakness or fatigue.  These are observable except possibly for fatigue.  .  There, I think it is a question of age and wearing.  I think that can probably be shown by broken strands.  Certainly, checking regularly and as they say, when you think something should be changed, you had better change it.

They are designed to shed the upstructure if the weather is too tough, so that the hull will survive and be a hospitable home for the sailors.   But back to the question of replacing or not replacing the rigging.   Perhaps the best thing would be to test the rigging, appropriately.   Bridges are tested by putting extra weight on them and measuring the deflection of the bridge.   Could one put extra tension on the rigging and so determine the safety of the rigging?   Bob
