J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment PHRF and Spin Pole Length

Generally with PHRF, the width of the spinnaker (SMW) is a function of pole length (SPL). 180% of SPL without a penalty. You really want to project the spinnaker out away from the boat as much as possible.

I've never really tried flying a class chute with a short pole. I 'spose it would work, but I don't know how efficient it would be.
