Erector pole makes it easy
I singlehand rig and sail my 170 all the time and have little trouble even being 5' 6" and a whopping 130lbs wet. I like the idea of the erector pole but, being cautious, I raise the mast, put the pole in place, and quickly move to the front of the boat and hang onto the forestay until I have it secured. Ideally, someone can hold the mast and even put some forward pressure on it to assist your pulling the forestay till pinned. I don't like to depend on the pole to hold the mast for long JUST IN CASE something were to go wrong, you don't bend a mast, or knock yourself or any not too saavy passersby on the head. You can easily fashion a pole from wood that would probably work as good or better than the one from Hunter. I have used the winch once and thought it a waste of time.
