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.
