You have a Z spar rig but it is designed to handle a spinnaker. Suggest a simply a symetrrical spinnaker vs. a racing spinnaker. Of course use in light airs is suggested. I will leave it up to the fine folks here to advise further. Jackdaw, can you help also. Thanks for all who have responded. As for Kermit, the Crescent Moon reminds me of the Johnny House Moon. Yikes I have done it and now the Oh Croaking is going to happen from green frog.
