I'll add my welcome aboard, as well. I have that boom too and always figured it was a spinnaker pole, but maybe not??? Seems too hefty to be a whisker pole, but I'm still learning. My boat came with a spinnaker but I was told by a rigger that it was not set up for a spin at the top of the mast. Not something i've chosen to worry about right now. Also, wanted to add that you might check out the ericson groups on facebook. There is a 27 group and an all inclusive group.
