People (as indicated above) do use their poles even if they don't fly a spinnaker
. However, as you gain more experience with the boat, there will come a day when the air is light, and you just want to give it a go with the spinnaker. Do this where there is lots of room to run down, blanket it behind the main, and take it down. You need the room till you've practiced more.
As you have given us no details relative to the boat, there's little more to say. If it's over 50', you'll probably want to rig the pole up the mast
, 'cause it'll be too long to manage easily by yourself. At 19 ft., ours is mounted up the mast
