I've commissioned Pineapple Sails of Alameda, CA to build me a new asymmetrical spinnaker. We're going with AIRX 700, an epoxy-impregnated nylon fabric which they describe as light enough to fly in less than 10 knots but strong enough to flog in 25. It will set and douse from a spinnaker sock.

Based on a bowsprit length of 2'1" past the stem, I estimate the new sail will come in around 850 square feet.

I can't wait to try it!
