[Public-list] Bronze turnbuckles - Inspection

[Mike Lehman]

This is great info. It is what I was trying to establish, that is - a list 
of boats who have had mast failures, the conditions surrounding the incident 
and the probable cause of the failure. I don't want to alarm anyone, but I 
think the spreader failure is possibly a very likely cause on the boats that 
have the round spreaders. Many years ago, after I witnessed the 527 
dismasting, I took my mast down and inspected the spreaders. What I found 
was the the aluminum spreaders fit very loosely in the SS socket and as a 
result of rocking in the socket, they had nearly worn through the aluminum 
tubing on the bottom where it rubbed th socket. I bought new spreaders and 
put a sleve inside the socket to make them fit tight. That was 22 years and 
they are still fine, but I inspect them carefully each year. I suggest that 
others with these spreaders look at them closely.

Kris:
     There are three lost of rigs that I know of in the Canadian fleet. I 
believe
Candy Cane  #583 lost her rig in a knock down in the Fujinon 300 with Peter 
Ashby
at the helm in the early 1990s. It was a particularly nasty storm that came
across the lake after dark about the Niagara River mouth and devastated many 
in
the fleet. John Birch can tell you more as he was in it and survived to 
finish
the race with his AL30, Wind Rose,  #544. The Fujinon was the original 300 
mile
race around Lake Ontario, now known as the Lake Ontario 300. Wanderlove, KC 
578
lost some of her rig on a south wind while tied to a wharf at Burlington 
B&SC
when two rigs tangled and locked up at their finger docks, (so always make 
sure
masts don't line up across the finger), and Jazz # 648 lost her rig in the 
last
race of the season last fall due to either a  spreader failure or too much
compression on the mast at the spreader and no compression fitting within 
the
mast. You can check that one further with John Kitchener.
     The two total failures were both in race boats,  under quite abnormal 
stress
in the first case and certainly stress in the second. I sometimes question 
how
tight the rigging needs to be before we get the stress too great and either 
force
the stick through the deck or collapse the carrying beam,  or lose the rig.
