hmmm. While I'll admit that I haven't looked closely at the SJ 21, I have a hard time imagining that the pole can't live on the boom. This works very well on most small boats, and can even work on larger boats with a light carbon pole. What it accomplishes is largely obviating the need for anyone to go forward of the mast to rig the pole.
