It is time for me to replace my centerboard pennant--now 6 years old. 

The yard likes to go with stainless steel wire, which is the same as the 
original pennant delivered with the boat when new in 1995. 


I am considering using an equivalent or stronger dyneema line but have a few 
questions for the list before I proceed. 


1. A portion of the pennant is always exposed to the sun--between the aft cabin 
top winch and the turning blocks which direct the line below thru the SS tubes. 
How does this portion of the line get protected from the UV? I think a covered 
line would provide protection but the cover may not fit thru the SS tubes which 
take the line to the board. Further, the cover on the line should probably not 
stay in the water below the surface since it is likely not dyneema. 


2. The current SS wire is bent in a loop and swaged and led to a winch with a 
3:1 purchase.  In the up position, the purchase and winch (and line clutch) 
hold the board up. When the board is fully extended, it is stopped by a fitting 
that 'catches' the swage and stops the board at a depth of ~ 7' 3".  At this 
depth, the leading edge of the board matches the leading edge of the 
centerboard trunk (and the board is supported against athwartship forces by the 
trunk).Thus the board is always held by the pennant, whether it is up or down. 
Without a swage fitting, how will the line hold the board up while it is 
extended? 


Hopefully some center-boarders on the list have switched to line and come up 
with solutions. 


Thanks,
