Bill,

Yes, that 39 still had the original “broach coach” barn door rudder in 1977.
The 1977 Transpac was one of the windiest Transpacs on record.  On the 
stormiest night we rounded up multiple times an hour.  IIRC 7 race boats were 
dismasted that night.  Learning from sailing through that with the short 
rudder, for the 1979 Transpac the owner upgraded to the newer rudder design and 
a bigger steering wheel.

The new rudder was a significant upgrade in control when pushing hard off the 
wind.  We also used a blooper to help balance the sail plan for DDW in trade 
wind conditions.
(That 39 was built in 1973 and was hull #49.  As the “Midnight Special” under 
Steve Crary’s ownership it held the Vic-Maui race record for <40’ for many 
years.  When I sailed on her (still the “Midnight Special”) the owner was Verne 
McCullough (1976 to +-1983).  Last I heard she was still in the PNW named 
“Discovery”.)

Our woodruff key failure analysis indicated the key was undersized and slowly 
slipped down out of the interface with the quadrant.  The failed key showed it 
sheared when just under ½ of its length was still in contact with the quadrant.

That is a scary tale. When I disconnected my rudder, I thought for sure that 
the key was redundant, as the quadrant clamped onto that shaft so hard when you 
tightened it that I couldn't imagine it's ever slipping.  I have to ask, was 
that the original barn door rudder? Because, I can't imagine that happening 
with one of the newer, balanced Spade rudders that came after. My 39 would sail 
itself without even touching it for miles. And then you only needed fingertips.
