shroud failure-Catalina Morgan 51

[Ken Heyman]

I ran across this today. I hope our c34 rigging doesn't have too much in common with the failed rigging on this 1991 Morgan 51. Lots of criticism of the "screwed together" configuration.----- Also a negative reference to "Taiwanese" rigging.


That toggle end is definitely 'screwed' and a those 'thread roots' are a REAL good source for the propagation of crevice corrosion. This type of T bolt is common on Taiwanese boats/rigging from the 80s and is VASTY inferior - and the typical failure as shown in the pic. T-bolts should be solid, forged ... not a screwed together configuration. This one probably has the T-cross section also screwed into the toggle shaft --- very typical of 1980s Taiwanese rigging 'stuff' (Grand Deer was most infamous for the manufacture of such 'crap').
This sort of failure, crevice corrosion, is common with 300 series stainless and should entice one to completely disassemble and visually inspect rigging screws and 'turnbuckles' on a regular basis.
