Rick, thanks for all the info. This forum has been great. Lots of good info. from sailers who apparently know and love sailing. I'll get the measurement info to you soon to see what you can put together. I'm still haven't decided on the course of action (spinnaker vs hooter), FX-1 Tony seemes to have put together a pretty slick spinnaker snuffer system. I am becoming a bit concerned about the possibility of mast breakage (a topic that has come up several times) and would like to know your insights. Thanks
