I think I do a good job of inspecting the rigging very frequently- just bought new shrouds and bridle stays (from the foil to the hulls) and redid one trap side. Also replaced the pins. I think I will probably make a habit in the future of loosening it by at least one pin hole after sailing.
The I20 you are talking about- I doubt you pulled on anything- but was the rig tight? or was it from flopping around.
