I did a race called the Space Coast 45 with Eric Arbogast on his ARC 21. When we got to the launch spot, I asked him what he wanted me to do. I was shocked when he said just hang out, I want to set it up myself. So I just stepped back and watched as he rigged this "Two Person" boat by himself in very short order.
He fabricated a "Gin Pole" according to ARC specs. They sell them and have an example of one on their website:

We had a great race. The weather was perfect. We were running second most of the day but ended up 4th.
