[Rhodes22-list] Update on IMF outhaul/furling running rigging changes made over the winter

[Chris Geankoplis]

Hey Reuben,
Thanks for sharing the project. We finally pulled Xenos today. The high was
28 with a 15 knot wind. Too cold here in Kansas. We will try to do the mods
before spring sailing. Hope to see you in a month or so.
