Hi Bill,
Nice, these are awesome instructions! I do plan on eventually flying symmetric spinnakers too (if I take the boat to Hawaii I'd be crazy not to).
Can you elaborate on the problems flying an asymmetric on a boat not designed for one? I know that without a bowsprit, the asym is just not far enough away from the main to fly cleanly. By adding one, the luff should have enough room to rotate to weather as I turn downwind. It's deep broad reaching that I want - Ananda already goes like a bat out of hell on a beam reach, I'm not worried about more speed reaching.
