Is there a rule of thumb for picking the proper whisker pole length?
It's for a 150% Genoa in this case.

========================================

It needs to be fairly close to the LP measurement to be really
effective, approximately 40 to 50% longer than the spinnaker pole.

Telescoping whisker poles are fairly popular which will give you some
range of adjustment. I find that getting the darn things out there
safely and clipped to the mast are a big challenge.
