Bill, I have an asymmetric spinnaker on my M-17 which goes from my bow pulpit to the masthead. I have a block at the masthead for the halyard and a block mounted on the pulpit for the tack line that runs back to the cockpit combing. The sail was made by Elliot/Pattison so if you mention my name they probably have the measurements on file. If you want to send me your e-mail to j_ellsworth@earthlink.net I can send you some pictures of how my rigging is set up. I have only used it a few times to date, but I also had the same set-up on my WWP-19 and it worked really well.

Quite bit of light air, especially on Monday. Got me thinking about options to use in place of my genoa for reaching. I looked throught the list archives and saw suggestions for symettrical, asymettrical, drifters, reachers. Are drifters and reachers really just another term for an asymettrical spinnaker? I am thinking of something with a wire luff to allow it to fly forward of the forestay. Maybe a 12-18" pennant from the stem head. Has anyone used the top of the bow pulpit? I don't think it would be an off the shelf item. Can anyone offer suggestions or experience with this type of sail on their M17? What would be the suggested square footage?
