[Public-List] Adjustable spinnaker/whisker pole

[Don Campbell]

Michael:
    The original Class Rules were that the Spin pole was equal to the J 
which was 10.5 feet. When the PHRF rules had a rule on whisker poles, it was 
that the pole could be 0.8 x the LP of the sail (not the original J). PHRF 
has since withdrawn all rules that pertain to whisker pole length and 
harnesses. Using that formula, the pole for a 150 genoa would be 10.5 x 
(150/100) x 0.8 which is 12.6 feet. If you ever want to use a 165 genoa 
(which is reasonable for a race fleet sail), then that length goes up to 
13.86 feet. I found that the way to make sure the pole did not go beyond the 
desired measurement was to make the harness for the spin pole such that the 
pole could not be extended beyond the limiting length. The next problem was 
the definition of a whisker pole, and that usually means the pole can only 
be attached at the mast and clew, (so the harness just hangs). It still 
worked well for the spin pole, because once contracted, it gives adequate 
wire for support to the upper mast . PHRF sailors can now hang the pole from 
the harness for any use.

Hello all,
Class rules are that the Spinnaker pole is to be no longer than 10"9".
In practice, what length poles are being used for extended whisker poles? 
Is 13 feet long enough to pole out a 150 Genoa for wing on wing downwind? 
Thanks for you input.
Michael
