Sounds like this is a reaching strut or jockey pole, this is different to a
spinnaker or whisker pole and is normally used to push out the guy to keep it away from the stantions and give you more of an angle going back to the
winch. This pole is normally pretty short, a lot shorter than the whisker pole would be. What length is it when compared to the distance from your
mast to the forestay at around 5 ft from the
deck. If it is long enough you can easily change the end fitting.
