Rigging for spinnaker
Generally speaking, your spinnaker pole should be the same length as the J measure of your boat. If you are racing it is important as your rating will be penalized if greater as it is a factor of the spinnaker girth. Maximum allowed used to be Girth = 1.8JI would suggest buying a track with an adjustable ring rather than a mast fistting for the spinnaker pole attachment. It will give you better control.If your masthead already as a spinnaker bail it is a simple matter to get hoisted up and rig a sheave with a halyard. If not, you will need to find one and install it you you can rig the sheave and halyard, which have to be above your forestay in order to be able to gybe the spinnaker properly.Good Luck
